Re: OpenGL linking problems

Oh, I guess you have a makefile generated by cmake? In which case you need

Ok, now there is some useful output. I see an -lGL, what else should I be looking for?

Oh my! That's very confused about if it's building a w32api or an X11 application.


At the very least, you should not be linking with /usr/lib/w32api/libopengl32.a.

comctl32, vfw32, gdi32, wsock32, ws2_32 also seem unlikely to be right.

../../../bin/libvtkftgl.a(FTGLPixmapFontRenderOpenGL.cpp.o):FTGLPixmapFontRenderOpenGL.cpp:(.text+0xe):

../../../bin/libvtkftgl.a(FTGLPixmapFontRenderOpenGL.cpp.o):FTGLPixmapFontRenderOpenGL.cpp:(.text+0x7d):

../../../bin/libvtkftgl.a(FTGLPixmapFontRenderOpenGL.cpp.o):FTGLPixmapFontRenderOpenGL.cpp:(.text+0x92):

collect2: ld returned 1 exit status

These symbols are provided by libGL, but you'll notice that libvtftgl.a comes after that on the command line you are using.
