glew: undefined reference to `_imp____glewFramebufferTexture2D'

[Mixpicles]

Hallo,

i want to use Framebufferobjects,
I have glew32.lib
i call glewInit(); all fine
Only when calling
glFramebufferTexture2D( GL_FRAMEBUFFER_EXT,
GL_COLOR_ATTACHMENT0_EXT,
GL_TEXTURE_2D,
fbo_render->texture(),
0);

I get the error mentioned above
I would be very grateful for any hints leading to the solution of this problem
Regards
