I'm wondering whether pkg-config might not be outputing correct flags
for freeglut.
For example this programme:
#include <GL/glut.h>
int main(void)
{
return 0;
}
- fails to build with:
cc `pkg-config --cflags --libs freeglut` foo.c
because:
In file included from foo.c:1:
In file included from /usr/local/include/GL/glut.h:17:
/usr/local/include/GL/freeglut_std.h:143:13: fatal error: 'GL/gl.h' file
not found
# include <GL/gl.h>
^~~~~~~~~
1 error generated.
But it builds ok if we add /usr/X11R6/include to the include path:
cc `pkg-config --cflags --libs freeglut` -I/usr/X11R6/include foo.c
For me, "pkg-config --cflags --libs freeglut" outputs:
-I/usr/local/include -L/usr/local/lib -lglut
So should pkg-config also output "-I/usr/X11R6/include" in this case?
I'm running OpenBSD 6.8 GENERIC.MP#98 amd64
Thanks for any clarification,
- Jules
