RE: [Mingw-users] Another user who can't link the opengl libraries...

[Wu Y. <ad...@ne...>]

Because the OpenGL library uses the stdcall convention. For more information
about stdcall and your current circumstance, have a look at

http://www.geocities.com/yongweiwu/stdcall.htm
  or
http://mywebpage.netscape.com/yongweiwu/stdcall.htm

The "-h" option of pexports might help. Have a try.

Best regards,

Ok, thanks to Magnus Bondesson (below), I got the latest dll, and for good
measure I created my own library (.a) file using impdef and dlltool.  I did
the same for glu32.dll and opengl32.dll.  This eliminated all the former
errors, but now I have a shorter list of new ones:

M:\>gcc -o gl.exe gl.o -mwindows -lglut32 -lglu32 -lopengl32
gl.o(.text+0x16a):gl.c: undefined reference to `glutSwapBuffers@0'
gl.o(.text+0x264):gl.c: undefined reference to `glutPostRedisplay@0'
gl.o(.text+0x325):gl.c: undefined reference to `gluPerspective@32'
gl.o(.text+0x32a):gl.c: undefined reference to `glutPostRedisplay@0'
gl.o(.text+0x4d5):gl.c: undefined reference to `glutInitDisplayMode@4'
gl.o(.text+0x4ec):gl.c: undefined reference to `glutInitWindowSize@8'
gl.o(.text+0x4fc):gl.c: undefined reference to `glutCreateWindow@4'
gl.o(.text+0x50c):gl.c: undefined reference to `glutDisplayFunc@4'
gl.o(.text+0x51c):gl.c: undefined reference to `glutReshapeFunc@4'
gl.o(.text+0x52c):gl.c: undefined reference to `glutIdleFunc@4'
gl.o(.text+0x53c):gl.c: undefined reference to `glutKeyboardFunc@4'
gl.o(.text+0x549):gl.c: undefined reference to `glutMainLoop@0'

I don't understand where the @ suffixes have come from?  They are not in the
def or header files.  Can anyone help?
