General
Q: Is it possible to integrate the win32-help as in dev-cpp, to get help on the items under the caret?
A: Integration of the win32 API helpfile should be a no-brainer. Someone could just write a really simple plugin and, upon invocation (through a shortcut possibly), look at the word under the cursor and invoke windows help... If you think you 're up to the task, I can help you with all the info you need. If not, I could write it myself but no promises on a release date ;)
Q: What licence is Code::Blocks released under?
A: GNU General Public License 2 (GPL)
Compiling
Q: What compiler can I use with Code::Blocks?
A: Code::Blocks philosophy is to be able to use any compiler on earth! Well, almost.
As a matter of fact it largely depends on the used compiler plugin. The one provided with the default Code::Blocks installation, supports GNU GCC (MinGW/Cygwin), MS Visual C++ Free Toolkit 2003, Borland's C++ Compiler 5.5, DigitalMars Free Compiler., OpenWatcom and Small Device C Compiler (SDCC).
Q: I imported a MSVCToolkit project/workspace, but Code::Blocks insists on trying to use GCC. What's wrong?
A: A little documentation problem ^^;. The "default compiler" is usually GCC, so when you imported it with "the default compiler", you told it to use GCC. To fix this situation, go to "Project", "Build Options" and select VC++ Toolkit as your compiler.
Another possibility is to put the Microsoft compiler as the default one. To do this, choose Settings - Compiler, choose the Microsoft compiler in the Selected Compiler section (top of dialog box) and press the Set as default button.
From now onwards, for all new projects the Microsoft compiler will be taken by default.
Q: My project should be compiled with a custom makefile. Is it possible with Code::Blocks?
A: Yes, you can. You need to change two different settings:
a) In "Compiler Settings", under the tab "Other", there's a setting called "Build Method". Choose "Work with makefiles".
b) In your project's Properties, you can choose to use a makefile. Check "This is a custom makefile" (WARNING! if you forget to check, the makefile will be OVERWRITTEN!)
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 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: How can I use a DLL without DEF or LIB files ?
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 tclsh script to extract import .lib from (any?) DLL (MinGW)
TODO: Someone might add some informations about problems
Request: Is MinGW or Code::Blocks able to support automatic generation of import libraries ?

Q: Where are the libraries for the OpenGL, Ogre3D, SDL, QT, wxWidgets etc. projects?
A: They're not bundled. The templates were provided for your convenience, but you need to download the libraries on your own. In common terms, "batteries not included" :)
Q: Is it possible to use Visual C++ 6.0 with Code::Blocks?
A: MSVC++ 6 is not a C++ compiler. It was made before the C++ standard, so it compiles some language that isn't C++. Upgrade.
Q: I got this error when compiling: Symbol "isascii" was not found in "codeblocks.dll"
A: Make sure you didn't mix up the MSVC headers or libs with the MinGW ones.
