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 ;)

Since version 1.0-beta5, no it is not. Code::Blocks works with GNU "make" [http://www.mingw.org/download.shtml (here)] or without it (default). To choose the build method, go to "Project/Build options", switch to the "Other" tab and select the build method you prefer.

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 and DigitalMars Free Compiler.

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.

''As of version 1.0-beta6, if a default MinGW installation is not detected, a Dev-C++ installation is checked for and is used if detected.''
 
−
 
 
−
You need to take two steps. First, set the compiler master path to the dev-cpp folder. It's under "Settings/Configure plugins/Compiler" in the "Programs" tab...
 
−
Second, you have to add two additional compiler (include) dirs. Go to "Settings/Configure plugins/Compiler" and in the "Compiler dirs" tab add "dev-cpp\include\c++" and "dev-cpp\include\c++\mingw32" (substituting "dev-cpp" with the actual dev-cpp installation folder).

−
== I just installed Code::Blocks Beta4 and I can't compile anything with BCC. ==
 
−
 
 
−
BCC is not supported 100% yet, unfortunately... The next release (namely 1.0-beta6) should address all BCC issues.
 
−
 
 
−
== My project should be compiled with a custom makefile. Is it possible with Code::Blocks? ==
 
−
 
 
−
Yes, as of version 1.0-beta4 it is supported. Go to project options and you 'll notice a "Custom Makefile" checkbox. If you check this, Code::Blocks will not create another Makefile for compiling but instead always use this Makefile. You have to understand, though, that it is your sole responsibility to keep this Makefile up to date.
 
−
Also make sure that "GNU make" is the selected build method for the specific compiler.
 
−
 
 
−
== I have downloaded MS VC++ Toolkit 2003 for a compiler. How do I tell Code::Blocks that it is my compiler? ==
 
−
 
 
−
Click on "Project/Build options" and select the compiler you want for your project/target.
 
−
 
 
−
== When compiling a wxWidgets project, I get several "variable 'vtable for xxxx' can't be auto-imported". What's wrong? ==
 
−
 
 
−
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.
 
−
 
 
−
== I can't compile a multithreaded app with VC Toolkit! Where are the libraries? ==
 
−
 
 
−
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.

== Where are the libraries for the OpenGL / SDL / etc. projects? ==
 
−
 
 
−
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" :)

== Is it possible to use Visual C++ 6.0 with Code::Blocks? ==

cylon> msvc++6 is not a C++ compiler. It was made before the C++ standard, so it compiles some language that isn't C++. Upgrade.
