Hello, I have been trying to compile a SDL/OpenGL program. The program works under linux, and I am able to get single-file OpenGL/SDL programs to compile and run with cygwin. When linking multiple files however, I get this strange errors: gcc -g view3ds.o gl_video.o sdl_event.o sdl_video.o object.o -o view3ds -lgl ut32 -lopengl32 -lGLU32 -lopengl32 `sdl-config --cflags --libs` -lm view3ds.o(.text+0x94): In function `resizeWindow': /home/Bob/prog/sdl2/view3ds.c:37: undefined reference to `_gluPerspective' view3ds.o(.text+0x3ca): In function `DrawScene': /home/Bob/prog/sdl2/view3ds.c:93: undefined reference to `_gluErrorString' view3ds.o(.text+0x3d2):/home/Bob/prog/sdl2/view3ds.c:94: undefined reference to `___getreent' view3ds.o(.text+0x7a2): In function `main': /home/Bob/prog/sdl2/view3ds.c:160: undefined reference to `___getreent' view3ds.o(.text+0x7dc):/home/Bob/prog/sdl2/view3ds.c:167: undefined reference to `___getreent' view3ds.o(.text+0x809):/home/Bob/prog/sdl2/view3ds.c:174: undefined reference to `___getreent' view3ds.o(.text+0x841):/home/Bob/prog/sdl2/view3ds.c:183: undefined reference to `___getreent'
I am using gcc 3.3.1 I find it strange that functions such as gluPerspective will compile/link fine in a single file program, but fail to work in project with multiple source files. Anyone have any suggestions? Thanks, Bob __________________________________ Do you Yahoo!?
