Public bug reported:
I was trying to compile a OpenGL program, but it fails to compile. I
suppose the package this bug is in is really libglvnd-dev, but I could
not find that in Launchpad.
Anyway, the linking error is:
/usr/bin/x86_64-linux-gnu-ld: cannot find -lGL
collect2: error: ld returned 1 exit status
This seems to be because the symlink libGL.so is missing. If I go to
/usr/lib/x86_64-linux-gnu and type:
sudo ln -s libGL.so.1 libGL.so
then compiling works.
Here is a (nonsensical) test program:
#include <GL/gl.h>
int main(int argc, char *argv[])
{
glEnable(GL_DEPTH_TEST);
return 0;
}
which I compile with:
gcc testgl.c -lGL
