Title: Compile Time Error
Post by: puneet_m on August 06, 2007, 09:23:22 PM
When I try to compile codeBlock I get the following error:

undefined reference to CreateBitmap@20. I tried including the necessary header file Windows.h, but the error does not go.

Any ideas as to what is the error?

Thanks,
Puneet

You don't link with gdi32.

Thanks for the reply. I linked with the gdit32, but now I am getting a different error:

undefined reference to '_imp__ZNK8wxStringllBeforeFirstEc'.

The error is because of the following line:
wxString option = token.BeforeFirst(':').

Thanks

You need to link with the wxWidgets library too.

I have linked with wxWidget library too. The library name is wxmsw28u_gcc_custom.dll.

Can you still see what the problem might be?

You should link against wxmsw28u.lib or libwxmsw28u.a (1st is for visual C++ 2nd is for mingw)

But all those things are set in the project files of codeblocks

What should I specify in Project->Build Options->Selected Compiler?

As of now I have specified GCC compiler...

In one of the manual the following statement is written --

You will be prompted to define the global variable $(#wx). Enter the location where you unpacked wxWidgets.

Hit the blue gear and lean back. Compilation may take 3-5 minutes, depending on the speed of your computer.

But I was not prompted to set the global variable. So can anyone highlight as to how to set the global variable.And how to execute the second statement

Thanks,
Puneet

Settings > Global variables.. and change the global variable.

Error says
C:\Program Files\CodeBlocks\bin\..\lib\gcc\mingw32\3.4.4\..\..\..\..\mingw32\bin\ld.exe: cannot find -lwxxrc

I have compiled wxWidget using mingW, and it got compiled successfully. But it does not have any library like wxxrc.

Thanks,
Puneet

wxxrc may be needed if you don't use a monolithic library.

If you use wxmsw28u_gcc_custom.dll, you should remove wxxrc from the linker libraries.
