| − | '''A:''' Code::Blocks is not a [http://en.wikipedia.org/wiki/Compiler compiler], nor a [http://en.wikipedia.org/wiki/Linker_%28computing%29 linker]. Release packages of Code::Blocks may include a compiler suite (MinGW/GCC), if not provided by the target platform already. However, this is provided "as-is" and not developed/maintained by the Code::Blocks development team.

| − | ==== Q: My project should be compiled with a custom makefile. Is it possible with Code::Blocks? ====
| |
| − | | |
| − | '''A:''' Yes, you can. You need to change one settings with Code::Blocks 8.02:
| |
| − | | |
| − | a) In your project's Properties, Check "This is a custom makefile".
| |
| − | | |
| − | And that's it! :)
| |
| − | | |
| − | ==== Q: I have downloaded MS VC++ Toolkit 2003 for a compiler. How do I tell Code::Blocks that it is my compiler? ====
| |
| − | | |
| − | '''A:''' Click on "Project/Build options" and select the compiler you want for your project/target.
| |
| − | | |
| − | ==== Q: When compiling a wxWidgets project, I get several "variable 'vtable for xxxx' can't be auto-imported". What's wrong? ==== | |
| − | | |
| − | '''A:''' You need to add WXUSINGDLL in "Project->Build options->Compiler #defines" and rebuild your project (or create a new project and use the "Using wxWidgets DLL" project option which adds "-DWXUSINGDLL" to Project->Build options->Other options).
| |
| − | Other errors with the same resolution are:
| |
| − | 'unresolved external symbol "char const * const wxEmptyString" (?wxEmptyString@@3PBDB)' or similar. | |
| − | If you were using 1.0-finalbeta and were trying to build a statically linked wxWidgets project, the cause of the problem was some faulty templates. But that's fixed now.
| |
| − | | |
| − | ==== Q: I can't compile a multithreaded app with VC Toolkit! Where are the libraries? ====
| |
| − | | |
| − | '''A:''' Sorry, no fix for your problem...
| |
| − | | |
| − | Your problem doesn't come from CodeBlocks. It exists, because the free VC toolkit (VCTK) doesn't provide all the libraries and tools which are coming with Visual C++ (VC) which isn't free, unfortunately.
| |
| − | | |
| − | Try buying a full-fledged VC++, or even better, download [http://www.mingw.org/ MinGW]
| |
| − | | |
| − | The libraries that can be obtained free of charge are:
| |
| − | | |
| − | Paths:
| |
| − | (VCT3) Visual C++ Toolkit 2003 - C:\Program Files\Microsoft Visual C++ Toolkit 2003\lib
| |
| − | (PSDK) Platform SDK - C:\Program Files\Microsoft Platform SDK\Lib
| |
| − | (NSDK) .NET 1.1 SDK - C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\lib
| |
| − | | |
| − | C runtime libs:
| |
| − | LIBC.LIB Single-threaded, static link (VCT3, NSDK)
| |
| − | LIBCMT.LIB Multithreaded, static link (VCT3, NSDK)
| |
| − | MSVCRT.LIB Multithreaded, dynamic link (import library for MSVCR71.DLL) (NSDK)
| |
| − | LIBCD.LIB Single-threaded, static link (debug) (VCT3, NSDK)
| |
| − | LIBCMTD.LIB Multithreaded, static link (debug) (NSDK)
| |
| − | MSVCRTD.LIB Multithreaded, dynamic link (import library for MSVCR71D.DLL) (debug) (NSDK)
| |
| − | | |
| − | C++ libs:
| |
| − | LIBCP.LIB Single-threaded, static link (VCT3, PSDK)
| |
| − | LIBCPMT.LIB Multithreaded, static link (VCT3)
| |
| − | MSVCPRT.LIB Multithreaded, dynamic link (import library for MSVCP71.dll) (none)
| |
| − | LIBCPD.LIB Single-threaded, static link (debug) (VCT3)
| |
| − | LIBCPMTD.LIB Multithreaded, static link (debug) (none)
| |
| − | MSVCPRTD.LIB Multithreaded, dynamic link (import library for MSVCP71D.DLL) (debug) (none)
| |
| − | | |
| − | Try setting the library linker directories to:
| |
| − | C:\Program Files\Microsoft Visual C++ Toolkit 2003\lib
| |
| − | C:\Program Files\Microsoft Platform SDK\Lib
| |
| − | C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\lib
| |
| − | in that order.
| |
| − | | |
| − | The ones listed as (none) above are actually present in the IA64 and AMD64 subdirectories of the PSDK lib directory. Not sure if these would work on 32-bit windows, however, they may if they are
| |
| − | meant to work in 32-bit compatibility mode on the 64-bit processors. Worth a try. Otherwise, you
| |
| − | can link statically to the C++ library instead of using MSVCP71.dll. If you really want to link against MSVCP71.dll you can try to create MSVCP71.LIB from the dll using lib.exe and sed. Search google for "exports.sed" for detailed steps.

| − | ==== Q: Microsoft calls MSVCRT.DLL a "Known DLL." How do I know if I can/should use it ? ====
| |
| − | | |
| − | Microsoft does not clearly describe what [http://msdn2.microsoft.com/en-us/library/abx4dbyh.aspx 'Known DLL'] means. A [http://www.zlib.net/DLL_FAQ.txt zLib FAQ entry] makes it much more clear. The short answer is that MSVCRT.DLL is a protected system component and to preserve system integrity it cannot be updated by any end user product installers but may be updated from time to time by system updates. If it works use it. If it doesn't you'll need use a non protected library such as MSVCR70 or MSVCR80 which not only can be updated but private versions can be installed. A small and simple C program is likely to work just fine with MSVCRT.DLL. A large and complex C++ program is more likely to need the additional functionality of MSVCR.
| |
| − | | |
| − | The MSVCRT.LIB that ships with 32 bit compiler Visual C++ Toolkit 2003 dynamically links to MSVCR71.DLL which is not present in a freshly installed Windows XP system. MSVCR only appears after some software package that needs it such as [http://www.adobe.com/ Adobe Acrobat Reader] is installed. This means that programs that depend on MSVCR must redistribute it or risk not working on a substantial percentage of systems for reasons not obvious to either the affected end users or the program supplier.
| |
| − | | |
| − | For projects that can safely use MSVCRT and where it is impractical to redistribute MSVCR, a Win32 MSVCRT.LIB that links to MSVCRT.DLL is available in any [http://www.microsoft.com/whdc/devtools/ddk/default.mspx Device Driver Kit]. It is best to preserve the MSVCRT.LIB provided by the compiler and alter the name of the MSVCRT.LIB extracted from a DDK. List your newly named MSVCRTxx in the lib. If you use MSVCRT.LIB from the Windows 2003 DDK you may encounter the link '''error LNK2001: unresolved external symbol ___security_cookie'''. This can be solved by switching to the MSVCRT.LIB in the Windows XP DDK or by linking '''bufferoverflowU.lib''' found in the Windows SDK. A Win64 MSVCRT.LIB that links to MSVCRT.DLL is available in the Windows SDK or Platform [http://www.microsoft.com/downloads/details.aspx?FamilyId=E15438AC-60BE-41BD-AA14-7F1E0F19CA0D&displaylang=en PSDK].
| |
| − | | |
| − | To prevent problems it is recommended to include both /MD and /NODEFAULTLIB:MSVCRT switches so that problems come up at link time instead of random crashes at run time. Be sure to load your programs into [http://www.dependencywalker.com/ Dependancy Walker] to ensure that functions aren't being linked into both MSVCRxx.DLL and MSVCRT.DLL. It is essential that malloc, calloc, realloc, free, and related memory allocation functions all import from the same DLL.

| − | | |
| − | '''A:''' I tried to find a solution, and the following script solved the problem for me. I used a cygwin environment for ''tclsh'' and ''sed'', but the MinGW tools for ''objdump'' and ''dlltool''. See here [http://wiki.tcl.tk/2435 tclsh script to extract import .lib from (any?) DLL (MinGW)]

| − | | |
| − | ==== Q: I would like to compile a project using some non-standard libraries. How can I indicate to CodeBlocks that these libraries and include files exist? ==== | |
| − | '''A:''' You can specify them for your global environment or just for your project.
| |
| − | | |
| − | For global environment :<br />
| |
| − | - Menu <i>Settings/Compiler and debugger</i><br />
| |
| − | - In the <i>Global compiler settings</i>, select the directories tab<br /> | |
| − | - Add the required paths for compiler and linker.<br />

| − | - Right click on the project then select <i>Build options</i><br />
| |
| − | - Select the directories tab<br />
| |
| − | - Add the required paths for compiler and linker.<br />
| |
| − | - Add your specific libraries in the linker tab.<br />
| |
| − | - Pay attention to project settings and target settings.
| |
| − | ==== Q: How do I use both Debug and Release builds of wx libraries? ====
| |
| − | '''A:''' I would use the default method of doing it and the default folder naming.

| − | WX_SUFFIX="ud" // Unicode debug
| |
| − | | |
| − | I use WX_CFG when I am using a special configuration
| |
| − | WX_CFG="rc3"
| |
| − | | |
| − | Remember, the CodeBlocks globel variable WX needs to point to the wxWidgets folder.

| − | Example minGW build command for "Unicode debug" 2.8.0 RC3
| |
| − | | |
| − | mingw32-make -f makefile.gcc VENDOR=rc3 CFG=rc3 USE_XRC=1 SHARED=1 MONOLITHIC=1 BUILD=debug UNICODE=1
| |
| − | | |
| − | "VENDOR=" just puts rc3 in the DLL name; "CFG=" sets which folder the DLL is placed in. In this case in lib\gcc_dllrc3
| |
| − | | |
| − | Before using CFG in the mingw32-make build you need to do one prior wxWidget build without using it; else the build errors out. (See note below.)
| |
| − | | |
| − | "__WXDEBUG__" must be defined (in the codeblocks project setting) if you wish to link against the debug version of wxWidgets DLL. Else you will get a runtime error, when you try to run your project output.

| − | Note:
| |
| − | *I have never gotten the following command to work
| |
| − | mingw32-make -f makefile.gcc VENDOR=rc3 CFG=rc3 USE_XRC=1 SHARED=1 MONOLITHIC=1 BUILD=debug UNICODE=1
| |
| − | | |
| − | *unless I have first run this command on the same wxWidgets folders
| |
| − | mingw32-make -f makefile.gcc USE_XRC=1 SHARED=1 MONOLITHIC=1 BUILD=debug UNICODE=1
| |
| − | | |
| − | *I am guessing that the build without the CFG creates a file or directory needed by the build with the CFG.

| − | ==== Q: How do I troubleshoot an compiler problem? ====
| |
| − | '''A:''' I would start by turning on full Compiler logging. | |
| − | | |
| − | This is done by selecting the "Full command line" option Under menu "Settings" -> "Compiler and Debugger" -> "Other Setting" tab, "Compiler logging".
| |
| − | | |
| − | This option will make Code::Blocks output the exact commands it uses to compile your code.
| |
| − | | |
| − | Things to remember:
| |
| − | | |
| − | * You should review all the commands and their options; | |
| − | * If you don't know what an option or a command does please read the documentation for the compiler/linker you're using;
| |
| − | * Look for missing commands;
| |
| − | * For every source file (.cpp; .c; .d; etc) in your project, must have at least one command. This command must produce an object file (file extension ".o" if using gcc/g++ and ".obj" if using Visual Studio);
| |
| − | * Every object file should be linked in the final executable, if not there are undefined symbols errors;
| |

| − | ==== Q: How do I add version information to windows executables and dll's? ====
| |
| − | '''A:''' You need to create a reosurce file with the extension .rc and write the version info there. Then add that file to the Code::Blocks project you are working on.
| |

| − | ==== Q: How do I get Code Completion to work? ====
| |
| − | '''A:''' Did you check how code completion is configured ?
| |
| − | See "Settings/Editor", click on "Code-completion and symbols browser" in the left column and check the Code completion and C/C++ parser tabs.
| |
| − | | |
| − | From the 2006/11/30 nightly build, you can also add, in the project properties, directories to be searched when locating a file to parse .Right click on the project, click on Properties and select the C/C++ parser options.
| |
| − | | |
| − | They 're mostly useful when you don't add compiler search dirs in build options but use backticked expressions (e.g. `freetype-config --cflags`). In this case, the parser is not aware of where the source files are located. So, by manually adding the directory in the parser's search dirs you 're actually helping the parser find the files.
| |
| − | | |
| − | Of course, backticked expressions are not the only reason these parser search dirs are useful. As another example, I have a set of projects in a workspace. To minimize maintenance overhead, I 'm using build scripts to configure these projects. Now, although build scripts are an awesome feature, the C/C++ parser faces the same problem: it doesn't know where to search for files. The parser search directories come to the rescue again.

| − | ==== Q: How do I make Code::Blocks portable? ====
| |
| − | '''Just the main configuration'''
| |
| − | *run / configure C::B as usual | |
| − | | |
| − | ''Note:''
| |
| − | Code::Blocks will create a default.conf file that usually is placed into:
| |
| − | "C:\Documents and Settings\[your_user_name]\Application Data\codeblocks" (or %APPDATA%) on Windows or your usual home folder ("~/") under Linux. | |
| − | | |
| − | *place this default.conf file into the directory where the codeblocks binary is
| |
| − | *remove the default.conf file from %APPDATA% / home folder respectively
| |
| − | *just run C::B from within the C::B path and/or via script / link...
| |
| − | | |
| − | ''Note:'' Don't forget to remove all bad hacks you might have done previously that modify %USERPROFILE% and/or %APPDATA% on Windows. | |
| − | | |
| − | ''Note:'' If C::B does not find default.conf (its config) within the %APPDATA% / home folder it looks within the C::B directory (the one where the C::B executable is) next. If there is no config file, too it will be created in the %APPDATA% / home folder. So just make sure you are doing the right thing and C::B is portable just fine.
| |
| − | | |
| − | BTW: This does probably ''not'' apply for any other config file(s) where not C::B is the maintainer but e.g. plugins. The main config file just works like that.
| |
| − | | |
| − | | |
| − | '''Complete mobile with compiler and plugins'''
| |
| − | | |
| − | An alternative way to make Code::Blocks ''completely'' portable can be achieved by following these steps:
| |
| − | *Set up a SVN compiled version (Linux)/a nightly (Windows) in the portable directory of your choice
| |
| − | *WINDOWS ONLY: Move your compiler (likely Mingw) into the directory where the nightly Code::Blocks you just set up resides so that you get codeblocks\mingw
| |
| − | *Linux systems will have a compiler anyway so that step is not necessary for Linux
| |
| − | *Next you will need a script to change your home data variable and launch Code::Blocks
| |
| − | *Create a new file in your new Code::Blocks directory (launcher.sh for Linux, launcher.bat for Windows) and open it with an editor
| |
| − | *Paste the following script in there and save it:
| |
| − | '''LINUX SCRIPT'''
| |
| − | #!/bin/bash
| |
| − | HOME="`pwd`/settings"
| |
| − | mkdir -p "$HOME"
| |
| − | ./codeblocks $*
| |
| − | | |
| − | '''WINDOWS SCRIPT'''
| |
| − | set APPDATA=%~dp0settings
| |
| − | mkdir %APPDATA%
| |
| − | START /D"%~dp0" codeblocks.exe %*
| |
| − | | |
| − | *LINUX ONLY: Make the file you just created executable: chmod +x laucnher.sh
| |
| − | *You can now launch this by either typing ./launcher.sh (Linux) or by doubleclicking it in Windows
| |

| − | '''New portable Code::Blocks portable loader in Windows''' | |
| − | Biplab, an active developer of CB, has released the portable CB loader v0.1.1 in his Blog
| |
| − | | |
| − | Steps to use it:
| |
| − | | |
| − | you can download the CbLauncher v0.1.1 from [http://biplab.in/2009/04/creating-portable-codeblocks-part-2/ Creating Portable Code::Blocks] to run Code::Blocks portably.
| |
| − | | |
| − | Steps to use Cblauncher:
| |
| − | | |
| − | #Download a nightly build with revision > 5334.
| |
| − | # Extract them to a folder.
| |
| − | #Extract CbLauncher.exe to same folder where codeblocks.exe file is present. After extraction, CbLauncher.exe and codeblocks.exe should be in same folder.
| |
| − | #Now double click on on CbLauncher.exe file to run Code::Blocks in a portable manner. | |
| − | | |
| − | Also, see [/index.php/topic,10360.0.html Portable Code::Blocks] for more details

| − | == Issues and Workaround ==
| |
| − | | |
| − | === Q: Sometime, in the text editor, space bar triggers Code Completion, how do I fix that ? ===
| |
| − | | |
| − | '''A:''' Informations found on the forum.
| |
| − | | |
| − | It's possible to fix this issue editing the keyboard entry in /etc/X1/xorg.conf file. However, some recent distribs use HAL, therefore xorg.conf is empty (since Ubuntu 8.10 for instance). It's also possible to use a setxkbmap tool.<br/><br/>
| |
| − | | |
| − | '''''Hal Solution (Ubuntu 8.10 and above):'''''<br/> | |
| − | | |
| − | For Ubuntu (and other gnome desktops), another simple solution for the current user is to change a preference.
| |
| − | # Menu System => Preferences => Keyboard
| |
| − | # Select Tab Layout
| |
| − | # Edit "Layout Options..."
| |
| − | # Expand last option "Using space key to input non-breakable space character"
| |
| − | # Select the last choice "Usual Space at any level"
| |
| − | This is not system wide.<br/><br/>
| |
| − | | |
| − | A system wide solution would be to add an fdi file there (for instance)
| |
| − | /etc/hal/fdi/policy/99-x11-key_space_fix.fdi
| |
| − | put the right thing in it (I did not succeed), unplug your keyboard, plug it again.<br/><br/>
| |
| − | | |
| − | '''''Xorg Solution (prior Hal based distrib):'''''<br/> | |
| − | | |
| − | as root, edit /etc/X11/xorg.conf and find something like :
| |
| − | | |
| − | Section "InputDevice"
| |
| − | Identifier "Generic Keyboard"
| |
| − | Driver "kbd"
| |
| − | ...
| |
| − | Option "XkbVariant" "oss"
| |
| − | EndSection
| |
| − | | |
| − | Try one of the following workarounds :
| |
| − | | |
| − | 1/ you comment the line
| |
| − | Option "XkbVariant" "oss"
| |
| − | like this
| |
| − | # Option "XkbVariant" "oss"
| |
| − | | |
| − | 2/ you replace
| |
| − | "XkbVariant" "oss"
| |
| − | with
| |
| − | "XkbVariant" "latin9"
| |
| − | | |
| − | This works for Ubuntu '''prior 8.10''' (before hal)<br/>
| |
| − | | |
| − | It seems that KUbuntu requires the following line:
| |
| − | Option "XkbOptions" "nbsp:none"
| |
| − | <br/><br/>
| |
| − | '''''setxkbmap Solution:'''''<br/>
| |
| − | | |
| − | run this command before running Code:Blocks (works fines for KUbuntu)
| |
| − | setxkbmap -option nbsp:none
| |
| − | if it's not enough you can try :
| |
| − | setxkbmap -option nbsp:none -model pc 105 -layout fr -variant latin 9
| |
