windows - OpenGL + GLEW + MinGW application linking issue

Question

I'm getting some undefined references when building my project. Here's the build log:

**** Build of configuration Debug for project test ****

Here's my link command:

g++ -mwindows -l glew32 -l glew32s -l glu32 -l opengl32 -o test.exe srcwindow.o srcest.o srcmain.o

Is this correct? I'm using the 64-bit binaries of glew (I think the 32s don't mean anything). Were they only meant to be used with visual studio?

Here's the includes in my code:

#include "Windows.h"
#include "GL/glew.h"
#include "GL/wglew.h"
#include "GL/gl.h"
#include "GL/glu.h"
#include "test.h"

I am using Eclipse Indigo CDT, MinGW, Win32, OpenGL, and glew.

Answer 1

I solved "glew undefined reference" problems.

My development environment is eclipse CDT with MinGW on Windows 7 (x64).

The solution is the following 3 steps:

1. Add source code: #define GLEW_STATIC
2. Add linker flag: -lglew32s -lopengl32 -lfreeglut
3. Add compiling flag: gcc -DGLEW_STATIC

If needed, you have to add -lglu32 -glut32 etc.
