Hey list,
I just recently got a new gcc 5.1 package in arch stable, so I thought
I'd rebuild all of kde with it to see if I still get the kbuildsycoca5
crash (if arch's qt5 packages are still built with gcc 4.9). At any
rate, I'm not able to build even kdesupport anymore. Once kdesrc-build
gets to phonon it complains with an error in qglobal.h that I need to
build with -fPIC now. I've added that to my cxxflags in
.kdesrc-buildrc and it is passing it into the build command, but it
still complains. I know build.kde.org recently hit a similar issue,
how do we get stuff to build now that qt throws this #error even when
we follow it's suggestion?
phonon build error log here:

Do we need to "fix" the arch qt packages to build with -fPIC or something?
