Unable to link Glmark2 with libGL on fresh Debian Jessie

[aowenson]

So I have tried compiling Glmark2 for the first time on Debian Jessie which was freshly installed a week ago. All the libraries required by ./configure are installed and can be found by ./configure. However when waf performs the linking step after compilation it cannot find libGL ("cannot find -lGL). I can't work out from waf's help how to tell waf where to look for libraries during linking, and the only place I can think to ask for help is here.

The configure step completes fine:

user@host:/Code/glmark2$ ./waf configure --prefix=/local --with-flavors=x11-gl

When I build, tasks 1 to 65 complete successfully (although the font colour for 65 is orange/brown not green if that signifies anything). Task 66 fails:

Further proof that libGL is installed:

ldconfig -p | grep libGL.so
libGL.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libGL.so.1
libGL.so.1 (libc6,x86-64) => /usr/lib/libGL.so.1

This was not an issue with how waf was setup for Glmark2. Instead it was an issue with how Debian installed libGL. For future visitors, the fix is to carefully check that the targets of symlinks for libGL actually exist. My issue was that a symlink pointed to libGL.so.1.2.0 which did not exist; the fix is to create a symlink from libGL.so.1.2.0 to a libGL.so* that does exist.
