Hi people
I was just trying to compile a project in C::B and I got "... undefined referece to ..." messages to all opengl functions used by a static library being linked with the aplication.
(WinXP using C::B version 1.0rc2 with gcc)
The link libraries in the application are (in order they are entered) :
mingw32, winmm, opengl32, glu32, SDLmain, SDL, SDL_image, lib3d.a (the last is my lib)
the compiler directories:
C:\Arquivos de programas\CodeBlocks\include
C:\c\include
and linker directories
C:\Arquivos de programas\CodeBlocks\lib
C:\c\lib
..
SDL headers are in c:\c\include\SDL. The SDL .a files and my lib3d.a in c:\c\lib
The headers of my lib are in a up directorie
Here is the begin of the build log :

continue with more undefind reference messages...

The OpenGL template and SDL template works fine.
Also, if a copy the aplication source files to my library project and compile it as a console application instead of a static library (adding the librarys to the linker of course), it links without problem with OpenGL and a get an executable.
I read the seemed topics but didn't figure out wat is wrong in my project.
Please, can anyone help me ?
Thanks by now and sorry for my bad english
PS: I don't know if it matters by here is the build log of the library

Change the order of the link libraries. Order matters...
Because lib3d.a requires libopengl32.a, libopengl32.a must appear after lib3d.a in the linker command line.

thanks mandrav, it works now.
I did know that order do influence, but I thought that depended librarys comes before dependent ones, but it seems to be the inverse. :?
Thanks again. :D
