missing /usr/lib/libGL.so, pkg-config gl.pc file causes programs to fail to build

[Pietro Gagliardi (andlabs/pietro10)]

I test the software I write against GTK+ master, and for that I build cairo and pango master as part of the build process with jhbuild. After getting a new laptop with AMD graphics, mesa kept freezing so I switched to fglrx. The two libraries now fail to build.

cairo fails to link because it can't find -lGL, because it is stored in /usr/lib/fglrx, which is not included in the library search path for whatever reason. So far, solutions to the problem I've found online say to manually create a symbolic link to /usr/lib/fglrx/libGL.so in /usr/lib. There must be some better way, especially since this leads to the next problem.

In pango's case, it fails late in the build process because pkg-config can't find an OpenGL pkg-config file, which is required by the cairo one produced by the previous cairo build. I'm not sure what to do in this case.

I have installed fglrx-updates-dev as well, to no avail.

No idea if fglrx non-updates is affected either.

Ubuntu GNOME 14.10
fglrx-updates 2:14.201-0ubuntu2 installed via Additional Drivers
Lenovo G50-45
AMD A6-6310 APU with AMD Radeon R4 Graphics

Thanks.

Status changed to 'Confirmed' because the bug affects multiple users.

I can not install either fglrc or update.Am using ubuntu gnome 1410 64 bit. It worked fine on 1404.

bigdavesr: what issue are you having specifically? Are you saying installing fglrx itself fails for you?

[Dave Stroud (bigdavesr)]

Yes when I try to install from add. drivers it just stops an d reset to default. On using apt or synaptic it says broken pqackages un met dependacies.

That's a different issue from the one in this bug report but I'll try to diagnose it: what packages conflict?

And it isn't saying which packages are held or conflict...?

[Dave Stroud (bigdavesr)]

No its not. If it did I might be able to figure it out. It did the same on 1410.,but did work in 14.04.
