Currently, when compiling dev-qt/qtcore-5.0.2 with gcc-4.8.0, an error occurs in qtimerinfo_unix.cpp. This patch solves the problem : http://qt.gitorious.org/qt/qtbase/commit/d9ff510f02bba63dabe7a081a68296056a89ae4c?format=patch Reproducible: Always
If you are using gcc-4.8, I'm sure you'll also have no problems in using epatch_user or qt 5.1.9999, where this issue is fixed already.
