From QB64 Wiki
As with everything else, this list will be updated to correspond to new progress of QB64 so make sure that you are using the latest version of QB64 (version 0.923 released 3/12/10). Please note that it may take a short time to update this list.
Q: What is QB64?
A: QB64 is a BASIC compatible Editor and C++ compiler that creates working Executable files from Qbasic BAS files that can be run on 32 or 64 bit PC's using WINDOWS(XP, Vista and newer), LINUX or MAC(OSX only). The goal is to be 100% compatible with QuickBasic 4.5 plus add hundreds of new abilities such as program icons and custom sized windows and a great Editor with a new Help Menu.
The new keywords add some new features such as playing music or sound files and instant access to 32 bit graphics file images. Also TCP/IP internet communication is available to download files, email messages over the web or play internet games. DLL Libraries can add more programming options and QB64 can access all of the new USB gaming controllers and printers.
QB is an abbreviation for QBasic or QuickBASIC which is an easy to learn language that grew very popular in the 90's. It uses simple syntax but holds great potential as there are methods to achieve nearly anything. Qbasic is NOT DEAD thanks to QB64!
Q: Does it have modern features? Do they HAVE to be used?
A: QB64 has PLENTY of modern features, but they do not have to be used. You may just want to run some of your old favorites.
You could code using the original QuickBASIC syntax all the way through and it should work as you expect it to or even better. QB64 is often faster and has none of the memory limitations that plagued Qbasic in the past! Give it try! See for yourself.
Galleon is constantly working on pure compatibility. You don't have to set it up differently to use the modern features as they are made to work alongside original QB code seamlessly (unlike FreeBASIC and any other modern BASIC out there). The modern statements are designed to go along with the BASIC philosophy and expand Qbasic into the future!
1) Full graphic functions for images up to 32 bit color. Alpha transparancies supported. 2) Instant loading of image files including BMP, PNG, JPEG, GIF and more... 3) Supports stereo sound files like WAV, OGG, MP3, speaker and volume control and more... 4) Animation is easy to do using _DISPLAY instead of page flipping. NO SCREEN FLICKER! 5) Clipboard reading and writing support. 6) Networking over TCP/IP Message Format and Email. 7) True type font and Unicode support for many Languages. 8) Integrated mouse and game controller input including scroll wheel support. 9) Support for C++, SDL, Windows API and other custom Dynamic Link Libraries.
Q: How do I install QB64 on Windows, Linux, Mac OSX or run programs in Android?
A: Since this is a relatively new project, it hasn't been tested as thoroughly as to have defined specifications. However, if you have a relatively new computer you will probably be fine. QB64 supports the following Operating Systems in one download:
- 1) Click the following link and Windows box to download QB64: QB64 Windows Downloads
- 2) Unzip to any folder path you wish. The ZIP file will create a QB64 folder for the program files.
- Executable programs are portable between like systems by copying the executable file as well as the QB64 DLL files.
- QB64 version .940 and above now contain a full version of the Ming Compiler! This may create an entry point error in Windows 2K.
- 1) Click the following link and Windows box to download QB64: QB64 Windows Downloads
- 2) Unzip to any folder path you wish. The ZIP file will create a QB64 folder for the program files. Check for MSVCRT.DLL errors!
- 3) If there is an error, unzip the contents of the ZIP FIX file into the QB64 folder after Qb64 has updated to the latest version.
- 1) Click on the following link and Linux box to download QB64: QB64 Linux Downloads
- 2) libsdl packages (dev and non-dev)(libsdl, libsdl-image, libsdl-mixer, libsdl-net, libsdl-ttf ) and GCC compiler must be installed.
- 3) After extracting qb64v0??-lnx64.tar.gz run the installation batch/script called setup.sh in the main qb64 folder to setup QB64.
- 1) You MUST install Apple's Xcode package for C++ compilation from their website: Xcode.html download
- (you won't be using the Xcode interface, QB64 just needs to have access to the C++ compiler it installs)
- 2) If you have a 32-bit MacOSX system, you should copy: qb64\common\libfreetype_alternatives\tiger_32bit\libfreetype.6.3.dylib over qb64\common\libfreetype.6.dylib if you are having difficulties. IE: Rename libfreetype.6.3.dylib to libfreetype.6.dylib
- 3) Click on the following link and MAC OSX box to download QB64 for MacOSX: QB64 MAC OSX Downloads
- Extract the MACOSX.zip file and run setup.command, found within the QB64 folder to install the QB64 compiler.
- Executable programs are portable between like OSX systems by copying the executable file as well as the common folder.
- To help launch executables without a console, a file called programname_start.command is created along with the program.
Q: How do I upgrade the 32 bit Windows version of QB64 to 64 bit functionality?
A: The process has been simplified a lot recently.
First, download a fresh QB64 version. (I'd recommend the latest dirty build.) Then download a x64 version of the min-gw compiler. Delete the 32-bit compiler from internal/c/compiler and replace with the 64-bit version. Run the setup_win.bat file (you may need to move it to the root QB64 folder for it to work).
Q: Why won't QB64 work on my computer?
QB64 currently supports Windows versions from XP to the latest version. Most Linux and MAC OSX versions are also supported.
Does your Windows system have another version of the MinGW compiler? Does it have Fortran or GFortran? You can check your environmental values using the following batch file which will create the settings.inf text file in the batch folder:
- The settings.inf file should hold environmental values similar to those listed below:
ALLUSERSPROFILE=C:\Documents and Settings\All Users.WINDOWS APPDATA=C:\Documents and Settings\User1\Application Data CLIENTNAME=Console CommonProgramFiles=C:\Program Files\Common Files COMPUTERNAME=PC1 ComSpec=C:\WINDOWS\system32\cmd.exe FP_NO_HOST_CHECK=NO HOMEDRIVE=C: HOMEPATH=\Documents and Settings\User1 LIBRARY_PATH=\F\G77\Llib LOGONSERVER=\\PC1 NUMBER_OF_PROCESSORS=1 OS=Windows_NT Path=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;\F\G77\bin PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH PROCESSOR_ARCHITECTURE=x86 PROCESSOR_IDENTIFIER=x86 Family 15 Model 1 Stepping 2, GenuineIntel PROCESSOR_LEVEL=15 PROCESSOR_REVISION=0102 ProgramFiles=C:\Program Files PROMPT=$P$G SESSIONNAME=Console SystemDrive=C: SystemRoot=C:\WINDOWS TEMP=C:\DOCUME~1\User1\LOCALS~1\Temp TMP=C:\DOCUME~1\User1\LOCALS~1\Temp
- Environmental values in red above indicate where another C compiler has altered or added to the Windows settings.
- Try to run the following TestQB64.bat batch file from the QB64 folder only:
@echo off REM set environmental values for QB64. Remove offending program paths from the values. set Path=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem set LIBRARY_PATH= REM start QB64 IDE. A BAS file can be dropped into this batch file to edit in IDE. REM this batch file must be run from the QB64 folder! Set QB64=%~dp0 CD "%QB64%" start qb64.exe %1
- 64 bit systems should use the PATH=C:\WINDOWS\SysWOW64 folder in place of the C:\WINDOWS\system32 parameter.
- If the batch file works, you can use it to edit and compile QB64 programs. You may want to uninstall the conflicting program.
Q: Are there any known incompatibilities?
A: There are some things that QB64 will not and NEVER was intended to do! The original concept was and is to provide a platform that allows older and NEW QBasic procedures and programs to run on the newer 32 and 64 bit personal computers. As you may have observed, this compatibility alone limits the access programs now have to DOS.
DOS is not fully supported, as this will require full DOS support to be emulated, however it will continually be updated to support more source code and more features, memory addresses, ports, etc. so that it always approaches 100%. If you don't use too many ABSOLUTE, INTERRUPT, PEEK, POKE and OUT statements you probably won't notice any difference between QB 4.5 and QB64 (and if you do, report it as a bug in the forums, remember to check if the problem has been reported before please!), you can expect the most common addresses for interrupts, etc. to be functioning. Galleon has also received a comprehensive list of memory and port addresses so that even some less common addresses may work as well. If you are unsure, try them!
Watch the CPU usage! QB64 is a lot faster than QBasic was and it does not have many of the size limitations that confined QBasic programming abilities. Having said that, care must be taken to assure that programs do not HOG resources! To do that, use speed limits when possible to keep the resources used to a minimum. Monitor Task Manager! It can tell you how much resources are being used in different parts of a program. The following keywords can lower the impact of your programs on those resources by releasing them to other programs:
- _LIMIT: Limits the loops per second in ANY loop and thus lowers the overall CPU usage.
- _DELAY: Pauses a procedure and releases unused resources for other programs.
- SLEEP: Stops or delays program procedures and shares resources.
QB64 can be fast when you need it to be, but take the time to consider the impact of your program on other programs as people SELDOM have only ONE program running and the OS has tasks it MUST do too! The following programs have KNOWN issues with high CPU usage:
Q: Why won't my QB64 compiled programs run in folders other than the QB64 folder?
A: QB64 requires certain DLL files to be in the program folder or in the Windows system path.
Copy each of the DLL files included with QB64 to the System32 or SysWOW64 folder. You may need administrator rights to do this!
Q: How do I find the current QB64 program path in Windows or Linux?
- Windows path:
PRINT PATH$ END FUNCTION PATH$ ' Get Current Directory 'Get path to executable in Windows DECLARE LIBRARY 'Directory Information using KERNEL32 provided by Dav FUNCTION GetModuleFileNameA (BYVAL Module AS LONG, FileName AS STRING, BYVAL nSize AS LONG) END DECLARE FileName$ = SPACE$(400) ' Sometimes 256 characters for a full path name is not enough Result = GetModuleFileNameA(0, FileName$, LEN(FileName$)) '0 designates the current program IF Result THEN 'Result returns the length or bytes of the string information PATH$ = LEFT$(FileName$, Result) start = 1 DO posit = INSTR(start, PATH$, "\") IF posit THEN last = posit start = posit + 1 LOOP UNTIL posit = 0 PATH$ = LEFT$(PATH$, last) ELSE PATH$ = "" END IF FileName$ = "" END FUNCTION
- Linux path:
PRINT path$ END FUNCTION path$ 'Get path to executable and directory of said executable on Linux 'Public Domain code DECLARE LIBRARY FUNCTION readlink& (path$, buffer$, BYVAL bufsize&) END DECLARE bufsize& = 500 'Initial size of the string to store the result in DO buffer$ = SPACE$(bufsize&) 'Create the buffer to put result in ret& = readlink&("/proc/self/exe", buffer$, bufsize&) '/proc/self/exe is always a symlink to our executable file IF ret& < bufsize& THEN EXIT DO 'ret& is how many bytes were actually put in the buffer. If they are equal, we need to make the buffer bigger and try again bufsize& = bufsize& + 500 LOOP exe$ = LEFT$(buffer$, ret&) 'exe$ is now the full path of the executable. 'This code just chops off the filename to give us the directory: FOR i& = LEN(exe$) TO 1 STEP -1 IF MID$(exe$, i&, 1) = "/" THEN EXIT FOR NEXT i& directory$ = LEFT$(exe$, i&) path$ = directory$ END FUNCTION
Q: How do I update the information in QB64 HELP?
A: Use the Update current page in the IDE Help menu selection to update a page. Use the Update all pages choice to update them all, but this may take longer. In general you may want to update monthly or a week after a new version release.
Q: Can I use the same libraries with QB64 that I used with QB 4.5?
A: If the libraries are pure QB 4.5 code then yes, otherwise no. QLB files are not supported but you can easily copy your favorite SUBs or FUNCTIONs to a text BI file and $INCLUDE them at the end of ANY program. Include them AFTER all SUB and FUNCTION code in the BAS file!
As of Dec 3, 2010 QB64 acquired DECLARE LIBRARY to allow users to reference C, Windows, SDL and other DLL libraries. If you find some functions that you like please share them with us at the forum! The following pages list working functions our members have found and tested:
Q: I can't get my QB 4.5 sourcecode to work in QB64! Why?
A: Perhaps that is because QB64 isn't 100% compatible yet, it is a work in progress. It is around 95-98% compatible right now, and that is a large number! As QB64 approaches the 1.0 version it approaches 100%. Look at the Unimplemented Qbasic Commands Forum for statements that are currently not available.
Compiler errors are another subject. Always try to test the program in Qbasic BEFORE trying to run or compile it in QB64! You may find syntax or other code errors that the QB64 IDE may not find yet as a bonus! Always check the code before blaming QB64!
Q: What files are required to run my QB64 GL compiled program in my Operating System?
A: QB64 GL uses DLL information internally so no external GL DLL files are required to be with your program EXE file. The GL version also only loads the required libraries for your code.
Q: How are foreign languages and keyboards supported in QB64?
A: As of version 0.922 (October 20, 2010) QB64 supports foreign language keyboard characters.
- Setting up a typing language in the QB64 IDE:
- Step 1: In the OPTIONS menu select DISPLAY, then check the CUSTOM FONT check-box.
- Step 2: In the OPTIONS menu select LANGUAGE, then select a Code Page (CP850 for example) and click OK.
See the Unicode page to setup a language in a program you create. There are also links to the various Code Pages that are supported. Also there are four new keywords to work with keypresses and map them to ASCII key character codes:
If you have any problems, post in the discussion board. In the meantime you can use any of these recommended ASCII methods:
Perhaps you can use the ASCII character codes. Go to the ASCII character chart and look for the character(s) you need. If you find them, remember the code number and use either CHR$(code%) or the Alt-number pad key method to type them into literal strings(real strings with quotes) only. The following QB64 program displays the characters available on your PC:
SCREEN _NEWIMAGE(800, 600, 256) font$ = "C:\WINDOWS\Fonts\cour.ttf" 'TTF file in Windows style$ = "monospace" 'font style f& = _LOADFONT(font$, 22, style$) _FONT f& COLOR 11 FOR c% = 1 TO 6: PRINT c%; CHR$(c%);: NEXT FOR c% = 14 TO 27: PRINT c%; CHR$(c%);: NEXT FOR c% = 32 TO 255: PRINT c%; CHR$(c%);: NEX DO: SLEEP: LOOP UNTIL INKEY$ <> ""
The ALT Key Method: Hold the Alt key down and enter the code number using the Number Pad only. When you release the Alt key, the character should be in the IDE string you are making. Characters can be added (concatenated) using the + between the literal string and CHR$(code) or by using a semicolon as shown below:
PRINT CHR$(165) + "ormally I don't use these keys. Do You " + CHR$(168) 'concatenation PRINT CHR$(165); "ormally I don't use these keys. Do you"; CHR$(168) 'semicolons PRINT "Ñormally I don't use these keys. Do you¿" 'Alt-number pad method
Ñormally I don't use these keys. Do you¿
- NOTE: You MUST use concatenation when defining a string variable using the CHR$ function character returns!
To cut down on typing CHR$(???) all day, define often used characters as string variables such as Q$ = CHR$(34) as shown below:
DIM Q AS STRING * 1 'define as one byte string(get rid of $ type suffix too) Q = CHR$(34) 'Q will now represent the elusive quotation mark in a string PRINT "This string uses "; Q; "quotation marks"; Q; " that might cause a syntax error!"
This string uses "quotation marks" that might cause a syntax error!
- Warning! Do NOT use Notepad for special characters as it won't display them! It is best to enter them in the IDE.
You can use ANY of the ASCII characters to add borders, arrows, and many other characters not available on the keyboard. Hopefully this information will cure your problem!
Q: MUST I copy or drag ALL of my program files to the QB64 folder?
A: NO! But you will not be able to compile or run it using the editor either. The editor requires that the files associated with your program be available when the program starts AFTER the EXE has been created! You can compile your program without using the editor however. It will require you to do a few extra things:
1) Use a batch file or a command line as follows: QB64 -c yourfile.BAS 2) Move the compiled EXE file back to the folder with the program files. 3) Copy ALL of the QB64 DLL files from the QB64 folder to your new program's folder. 4) Try the EXE file to see how it works.
QB64 Program Package ZIP file.
Q: Is there a way to use the compiler without running my program or using the IDE?
A: Yes! No other program files besides the BAS file are required! Use the following command to compile a program without running it:
QB64 -c yourfile.BAS
One advantage to compiling without running a program is that the QB64 editor will require that ALL of the necessary program files be placed inside of the QB64 folder or errors will occur when it is run! Also the EXE file will not be made or will disappear as it is no longer a valid application! To run the newly created EXE file, MOVE IT BACK to the location where your other program files reside.
The batch file below can compile any BAS file from any location using drag and drop. The EXE will be created in the QB64 folder:
@ECHO OFF Set QB64=%~dp0 Echo. QB64 path: %QB64% REM The QB64 path must designate the drive letter when compiling from another drive letter! C: CD\ CD "%QB64%" cmd /c start /low QB64.exe -c %1
You can associate the batch file to the Right Click Popup Menu's Open With dialogue choices when you right click ANY BAS file:
- 1) Right click any BAS file and move to Open With and click Choose Program in the pop-up menu.
- 2) Your batch file will not be in the program choices so select Browse.
- 3) Navigate to the batch file in the QB64 folder and click on it.
- 4) Make sure that the Always use this program box is NOT checked! Then save your choice.
Q: How do I LINK modules or INCLUDE SUB procedures in QB64?
A: QB64 allows you to $INCLUDE code or BAS modules into one module when it is compiled. Text .BI files containing SUB or FUNCTION code or entire BAS modules can be included in one module that will be compiled.
After the EXE is compiled, you do not have to even use the added code anymore! The EXE will contain ALL of the program code as ONE stand-alone program! This also allows you to add SUB code to ANY program that you desire. Use the following syntax and rules:
- 1) $INCLUDE TYPE definitions or DATA field code at the beginning of the module that will be compiled. Text code can be used, but must be renamed to .BI (cannot be a .TXT extension!) or kept as a .BAS module. SUB or FUNCTION code MUST be included at the end of the module code!
- 2) $INCLUDE SUB or FUNCTION code AFTER any SUB or FUNCTION code in the module that will be compiled to combine them. Otherwise QB64 will create an error stating that the INCLUDE statement cannot be placed there.
- 3) LINKING of program modules is accomplished by creating a NEW module and using an $INCLUDE statement for each module that is to be combined.
After you have created the include files, you can add them to ANY other program that requires them! Thus you will end up with smaller BAS files and SUB procedures that can be used over and over like libraries. The files are only used during a compilation.
Q: CHAIN doesn't work the way I'm used to...
A: CHAIN has been implemented in QB64 versions 0.851 up. Be sure to download the latest version of the compiler when available.
The statement also can use COMMON or COMMON SHARED to pass program information. However QB64 uses files to pass the information. If your program moves to a location other than the EXE file's location, the file may be inaccessable! To avoid this problem, make sure that your program can refer to that location using a path.
There are minor differences from QBasic in that it doesn't open a program in the same window and does not retain the previous screen mode or format. This problem will be addressed in future releases!
Q: Some screens look small. Can I enlarge them or make them fullscreen?
You can also create custom sized screens with page flipping and up to 32 bit colors using _NEWIMAGE.
Page flipping is available in most screens and the new _DISPLAY feature allows the images to be displayed when YOU desire.
Picture or image files such as BMP, PNG, JPEG and GIF are EASY to load using _LOADIMAGE.
Once images are loaded, all you have to do is use the image handle with any of the new statements and functions.
_PUTIMAGE GETs and PUTs images fast in ONE call. It can even stretch or compress the image sizes!
A: Yes, they are emulated to use the soundcard instead of the old boring monotone PC-speaker that is rapidly disappearing.
- 1) Multiple sound tracks
- 2) Volume and speaker control
- 3) Background music
Q: Can I use multiple monitors or Pole Monitors?
A: Yes, program windows can be moved to them automatically using _SCREENMOVE with horizontal pixel values that are negative for a secondary monitor on the left and greater than the screen resolution for secondary monitors on the right.
Note: If _FULLSCREEN is used the program will appear in the primary monitor only. Other running program windows may be pushed onto a secondary monitor on the right so a secondary monitor on the left is preferable in those circumstances.
Q: Why isn't the IDE always working as I would expect?
A: The IDE is currently being worked on, but it has a lower priority than the compiler (for obvious reasons), syntax checking isn't always working as you would expect, etc., Galleon knows about these issues and makes effort to resolve them in due time. The compiler is priority number one though and the IDE will be improved as warranted.
Report missed Syntax Errors here!
Q: If QB64 creates Basic programs why is there no Immediate Window?
A: Because there is no QB64 interpreter. All C code has to be compiled before it can be run, but you can run more than one instance.
QB64 uses the Immediate window area to suggest syntax for keyword entries and give the compiler status when compiling. To run code snippets or do program calculations using QB64 just open up another instance of the IDE. Each new instance of QB64 will create a new numbered instance of Untitled(n).exe when compiled. If you want to save the test code for later use, Save it as a BAS file name before closing that instance of QB64. Ihe IDE will always ask if you want to save new or edited code.
Qbasic and Quickbasic allowed BAS programs to be run in an interpreter to test the code. The Run Menu will allows the following:
Start F5 Compiles into EXE file and runs program(with code whiteout). ─────────────────────────── Start (Detached) Ctrl+F5 Compiles into EXE and runs program separately (no code whiteout). Make EXE Only F11 Compiles into EXE without program files if there are no errors. ─────────────────────────── Make Android Project GL Compiled program as Android project(enabled in Options)
Only the associated DLL files need to be included with the program EXE after it is compiled.
(The compiler can find Windows DLL files in the System folder and C++ DLL files in the QB64 folder.)
No additional program files need to be in the QB64 folder to Make EXE Only!The compiled EXE file can then be moved to a different folder holding the program files necessary when it is run.
Q: How can I slow my program down and/or use less CPU resources?
Not by using FOR loops! It would take a lot of loops just to slow QB64 down! Try _LIMIT to slow your program down and run at the same frame rate every loop. The integer value you enter determines the loop rate whether it is a DO...LOOP or a FOR...NEXT loop.
_LIMIT also keeps the CPU memory usage lower when used correctly. Use Task Manager or another CPU manager to monitor the percentage of use if it is over 50% and it doesn't need to be. Some QB64 programs can take up over 90% of the memory needed!
Q: Can I resize the QB64 Editor(IDE)?
A: Yes, use the Alt + Enter key combination to switch from windowed to full screen mode. This can also be used to resize a QB64 program screen!
There is also a way to set the window size in the Options Menu. Select Display and change the size from 80 columns and 25 rows to a larger size. The size cannot be less than 80 by 25! The size denotes the TEXT column and rows only! DO NOT MAKE IT TOO LARGE!
If there is ever a problem with an OPTION that you set, just Delete the .\internal\temp\options.bin file. Then restart QB64. You can find the program listed in the taskbar. Right click and select Close from the pop-up menu.
Q: The autoformatting doesn't work correctly in the IDE...
A: The autoformatting only has minor bugs which doesn't alter the actual execution of the code in any way, for now if you save your code in the current formatting it will format correctly in later versions of QB64. If the code you have is 'corrupted' by autoformatting, then please report it on the forums, because that would be a serious issue, if you can you should also provide code example of how it was corrupted.
Q: Does it work on Windows 98 or any OS older than Windows 2000?
A: No, not yet, it is a low-priority issue, since QB64 is made to run on new systems (WinXP -> Vista etc.), Galleon has said that he wants to make it work on Windows 98 too, so if you are patient it will eventually work there as well. It should work on NT, XP, 2000, Vista and Windows 7 using 32 or 64 bit systems. The .exe files produced by QB64 do work in Windows 98 as long as the QB64 DLL libraries are supported on that system.
Q: Can Line Numbers be removed from older program code?
Q: Does QB64 support CURRENCY values from PDS or VB programs?
A: Not directly, but _FLOAT currency values up to 4 decimal places can be multiplied by 10000(10 ^ 4) and converted to MKC$ string values using _MK$ with an _INTEGER64 value. _CV with an _INTEGER64 value divided by 10000 converts it back to _FLOAT values.
Q: What files are required to run QB64 SDL programs in Windows?
A: The QB64 compiler and EVERY EXE file created by the compiler are dependant on various DLL Library files to function properly. These files are found inside of the QB64 folder. This also explains why QB64 will create ALL EXE files in the QB64 folder no matter where the original BAS file is located on the computer. Your new program will require these files too, but you can move the DLL files to your shared SYSTEM32 folder to eliminate duplicates! Note: As of version 0.94(9/8/2011), QB64 now includes the full GCC compiler.
jpeg.dll libfreetype-6.dll libgcc_s_sjlj-1.dll *(.95) libogg-0.dll libpng12-0.dll libstdc++-6.dll *(.95) libtiff-3.dll libvorbis-0.dll libvorbisfile-3.dll SDL.dll SDL_image.dll SDL_mixer.dll SDL_net.dll SDL_ttf.dll smpeg.dll zlib1.dll * denotes DLL updated in (version)
cyberbit.ttf (12.7 MB v 0.92, October 2010)
C:\WINDOWS\SYSTEM32 or C:\WINDOWS\SysWOW64
This will allow all of your programs to run in any location without copies of the DLL files inside of every program folder. Administrator rights may be necessary to move them there! The DATA folder files are integrated into the compiler itself in versions .91 and above.
If you plan to make your program available for download, the DLL files listed above must be included with the program.
QB64 Program Package ZIP file.
The ZIP file can be used to unzip the DLL libraries into any program's folder location. It can also be used to create program download packages. Just create a folder with all of the relevant program files needed by your program and unzip the required QB64 files into it. Then you can ZIP the folder or all of the folder contents into your own zip program packages. We hope to have a package installer in the future.

Q: What are the Specifications by SDL Version?
AUTOMATIC VERSION UPDATES IMPORTANT: QB64 V0.91 users onwards do not need to download ANY Updates! Simply click on the QB64 FILE menu's UPDATE command (if QB64 hasn't already detected the new version) to download newer versions. You can allow or block automatic updates in the Options Menu. Enjoy, Galleon NOTE: Some auto-updates may take longer! Please allow them to finish completely. The Help menu About will tell which version of QB64 is currently running. The included Readme.txt file is also updated with the current version improvements. All QB64 versions after Version .94 will contain the full MinGW C++ compiler. Note: QB64 is currently being converted to Open GL graphics. When fully implemented, DLL files will no longer be required.

Bugs/Incompatibilities: -Severe memory leak related to GET/PUT fixed [0.926] January 30, 2011 NOTE: This version reduces the size of QB64 compiled EXE files by as much as 44%! The minimum compiled EXE size has been reduced from 875 KB to 495 KB. Newly implemented QBASIC commands: KEY ON, KEY LIST, ON KEY(n)..., KEY(n) ON/OFF/STOP, KEY index,string$, etc PALETTE USING New commands added to QB64: _SCREENMOVE newwindowxposition,newwindowyposition _SCREENMOVE _MIDDLE 'center window on desktop mywindowxposition = _SCREENX 'set window's desktop position mywindowyposition = _SCREENY _MOUSEMOVE xoffset,yoffset 'moves the mouse cursor myosinfo$ = _OS$ (See http://www.qb64.net/forum/index.php?topic=2495.0) Critical bugs fixed in: PRINT USING - EOF - handling of NOT operator - passing multiple arrays to functions KILL - READ - Other minor problems addressed There is a new menu item in the 'Options' menu called 'About' which will tell you which version of QB64 you have. After this update it will say 0.926 V0.92 Updates October 17, 2010 [0.923] DECLARE LIBRARY command added to allow for calling functions in external libraries (http://www.qb64.net/forum/index.php?topic=1712.0) [0.923] Various minor bugs/incompatibilities fixed [0.922] QB64 IDE can now use codepages, select them in the options->language... section. Note: A .TTF font MUST be in use to see the results. [0.922] New command: _MAPUNICODE unicodevalue TO asciivalue 'Maps UNICODE codes to ASCII values for purposes such as simulating codepages [0.922] New command: unicodevalue=_MAPUNICODE(asciivalue) 'Returns the UNICODE code that the ascii value is currently mapped to [0.922] Linux version updated [0.922] Significant bugs/incompatibilities corrected, including: -corrections to the passing of UDT members by reference -fixed memory leak in _FREEIMAGE (as _FREEIMAGE is called internally by QB64 for SCREEN management, it also affected some programs not calling _FREEIMAGE) -corrected mismatch in dimension count of multidimensional arrays passed to functions -corrections to the implementation of the FIELD statement (for other bugs/incompatibilities addressed, refer to the forum) [0.921] Various bug fixes and patches applied to V0.92 V0.92 Specific October 4, 2010 -Significant improvements to the QB64 input system have occurred primarily for multilingual and multiplatform reasons: i) The new _KEYHIT and _KEYDOWN functions can be used to monitor key press/release events/states. These also return UNICODE (UTF32) codes when UNICODE characters are entered. http://www.qb64.net/forum/index.php?topic=1368.msg12703#msg12703 ii) IME support added to facilitate entering Japanese, Chinese and Korean characters. Note: The font CYBERBIT.TTF is free for non-commercial use and is now included in QB64. It is only required to facilitate input via IME and not loaded unless the user switches to an IME input system mode. QB64 also locates several fall-back fonts under circumstances when 'cyberbit' is not present, therefore it is unnecessary to distribute this font with your programs. iii) QB64 now maps the UNICODE input of characters which appear in the CP437 extended range(128-255) to their correct character. This means characters with umlauts and other international characters now appear correctly when using INKEY$ iv) QB64 emulates scancodes based on what a stock-standard 101-key keyboard might return. Scancodes are language/platform specific, so this change means programs which do use INP will work as expected on all platforms. -Support for the FIELD statement added. -Some bugs/incompatibilities addressed but others will be corrected over coming weeks via automatic updates. (See the bugs/incompatibilities forum for further information) V0.91 Updates August 22, 2010 -The DATA folder (and its contents) are no longer required. You may delete them when/if you wish. -Various bugs & incompatibilites addressed http://www.qb64.net/forum/index.php?board=3.0 (of note: FREEFILE, FIX, INT, INPUT, INCLUDE) -Improved syntax checking -Removed blank pixel lines occurring between box drawing characters when using .TTF fonts 7/8/2010: -FILES command implemented V0.91 Specific -Primarily implements the QB64 auto-updater. http://www.qb64.net/forum/index.php?topic=1110.msg8195#msg8195 QB64 now checks for and applies updates to QB64 automatically or according to the update options you specify in the IDE. V0.9 Specific July 11, 2010 (Linux users must now run the batch/script file 'setup.sh' to build/setup/install QB64) -Primarily updates Linux pure 64-bit support -C++ components have been overhauled to be 64-bit compatible (affects all versions of QB64) -Further bugs/incompatibilities fixed (see forum for details) -Samples have been checked for Linux compatibility (eg. case sensitive filenames)
Q: Does a User licence come with QB64?
A: Yes, as of version 0.85 a licence comes with QB64 released as freeware. Read the licence.txt that comes with the download package for more information. QB64 will always be free to use with the current library files and the licenses DO NOT LIMIT the use of those libraries! You are also allowed to sell software that you create with the following stipulations:
QB64 SDL SOFTWARE LICENSE QB64 is currently released as freeware meaning that this download may be copied/distributed free of charge. All rights to the programs you create using QB64 (in both their executable and source form) belong to you. You are under no obligation to release the source code to the programs you create. You can sell the programs you create for profit. You are under no obligation to acknowledge that the programs you create were written in QB64 or reference the QB64 website in any way. The dynamically linked libraries (the DLL files you must include with your programs) are distributed under LGPL. Requirements for this can be found at the following URL: http://www.libsdl.org/license-lgpl.php QB64 and QB64 programs dynamically link to SDL (Simple DirectMedia Layer) libraries. SDL libraries are made available under the GNU Lesser General Public License (LGPL). Details of the SDL license requirements can be found at the above URL. Libraries are used in their 'standard'/unmodified versions and source code for these libraries can be found at: http://www.libsdl.org The QB64 compiler generates C++ code which is compiled into executable form by the MINGW GCC compiler. QB64 uses a version of the MINGW & GCC compilers found at the following URL: http://www.drangon.org/mingw/ The official version of MINGW GCC compiler can be found at the following URL: http://www.mingw.org/
- The choice of license makes a big difference: using the Lesser GPL permits use of the library in proprietary programs; using the ordinary GPL for a library makes it available only for free programs.
IMPORTANT LICENSING NOTE FOR QB64 GL PROGRAMMERS All executables which perform any kind of sound operation are subject to the LGPL license (due to incorporation of mpglibdll and OpenAL). Other components are licensed under various permissive licences. When sound components are included (thus the LGPL is in effect), the easiest way to meet terms of the LGPL is to make your program's source code (.BAS) available. If you are not using sound components, you do not need to release the program's source. If you are using fonts, you are bound by the terms of FreeType's license. Somewhere in your software package should include a notice that your program includes the FreeType library (see licence_freetype_ftl.txt for details) In all cases, you should distribute the LICENSE folder with your program. It should be noted that providing source code is not the only way to meet the conditions of the LGPL (eg dynamic linking) but it is by far the easiest from a technical point of view at this current time.

Q: How can I find what caused a Compiler error?
A: Compiler errors are often actually coding errors that both you and the IDE don't notice! Often it is a syntax error such as forgetting a quotation mark in a PRINT. Look for syntax errors too as the IDE still needs some improvements. The best way to get a clue to the problem is to run the following batch file IMMEDIATELY AFTER a compilation failure: CODE UPDATED 1/4/2011
@echo off ECHO. ECHO Diagnosing Latest Compilation Error ECHO. ECHO Please wait... ECHO. cd .\internal\c .\bin\g -w -Wall -I.\i -I..\..\ -L.\l qbx.cpp libqbx.o -mwindows .\i686-w64-mingw32\lib\libimm32.a -lwinspool -lmingw32 -ln -lmix -limg -lttf -lmn -lSDL -o ..\..\test64.exe cd ..\.. ECHO. ECHO. PAUSE
@echo off ECHO. ECHO Diagnosing Latest Compilation Error ECHO. ECHO Please wait... ECHO. cd .\internal\c .\bin\g -w -Wall -I.\i -I..\..\ -L.\l qbx.cpp libqbx.o -mwindows .\i686-w64-mingw32\lib\libimm32.a -lwinspool -lmingw32 -ln -lmix -limg -lttf -lmn -lSDL -s -o ..\..\ >..\..\0utput64.txt 2>&1 cd ..\.. ECHO. ECHO 0utput64.txt created! ECHO. PAUSE
Look for the word error in the resulting information. The errors often have to do with syntax or code errors not found by the IDE.
Q: How do I use the QB64 code Repository?
A: You can find a video tutorial here: Repository Video Tutorial
- I cannot stress enough that the QB64 repository is not an official QB64 release! Even though our contributors are individually appointed, I'm not responsible for the contributions of these other authors which could potentially be malicious.
Q: where I can view the C++ code before it gets compiled
Look in the QB64 internal\temp folder for Main.txt to get the C code used to compile the latest program.
Q: Where can I find information about a QB64 statement or function?
