[Mingw-users] [Q] Linker error when linking against static library which wraps OpenGL

[John F. <ha...@vo...>]

Here's the facts:

[1] Same code builds and runs under Linux

[2] run make to build libcgogl.a (my static lib which wraps
opengl), it all seems smooth.

[3] run make for client:
    g++ -o cli
 cli.o -L../library/lib/ -lglut32 -lopengl32 -lglu32 -lcgogl

    get errors like:

    ../library/lib//libcgogl.a(rect2d.o.b): In function
`GLdoubleRect2D::draw(double
    , double, double, double, bool)':
    file://D/library/rect2d.cpp:90: undefined reference to
`_imp__glRectd@32'
    file://D/library/rect2d.cpp:95: undefined reference to
`_imp__glVertex2d@16'
    ......

The _imp__gl<blah> stuff seems to be in libopengl32 and my
libcgogl.  Is there some ar option I missed?

If I try to build a good GLUT app that is an EXE using GLUT
and OGL directly... all is well... builds and runs.

What obvious thing have I missed?

Thanks.
