Hello. Is someone working on this issue? It is blocking one of my packages from building in fedora 18 "rawhide" while it builds fine in fedora 16 and fedora 17. Thus, my package cannot get into fedora or epel until this bug get fixed.

Apps should never link against libglapi. Never ever ever. It's an implementation detail of libGL, it is not API.

That said, the linker complaining when it's implicitly brought into the link and not usable seems like a real bug. I'll take a look.

It's not linking directly, this is the link command:

/usr/bin/c++ -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -O3 -DNDEBUG -Wl,-z,relro -L/builddir/build/BUILD/VirtualGL-2.3.1/staticlib -static-libgcc CMakeFiles/glreadtest.dir/glreadtest.cpp.o -o ../bin/glreadtest -rdynamic -lGL -lGLU -lX11

getting this error while trying to emerge "x11-libs/qt-gui-5.0.0_beta1:qt" the problem seem to have been fixed in Mageia and RedHat picked up the patch too.

the patch apply cleanly to media-libs/mesa-9_pre20120831-r1 and permit to pass src_configure, still failing later but that's another bug.

for the record:

> still failing later but that's another bug

yes and no, that problem was determined by circular dependencies in x11-libs/qt-{gui,widgets,opengl} and have been solved varying use flags and with emerge --nodeps; not worth a bug report, maybe for qt5 beta 2

mesa-8.1-0.19.fc18 has been pushed to the Fedora 18 stable repository. If problems still persist, please make note of it in this bug report.

That patch is not very good.

I've fixed it in my automake-gallium branch (http://cgit.freedesktop.org/~mattst88/mesa/log/?h=automake-gallium) which will be rebased often, so I can't give a commit hash, but the title is

> build: Link libglapi with pthreads

I guess I'll have to do something slightly different for 9.0.

Patches committed to master. Will wait a few days and cherry-pick to 9.0.

Fixed in 9.0
