I am not sure if I should open a new bug or join a similar bug#36690 The issue with a qmake which detects properties of cpu incorrectly. In my case it thinks that my processor AMD NeoII supports ssse3 which it does not.

By investigating comments on QTBUG-18688 I found that there is inconsistence in configure options and CFLAGS (or CXXFLAGS?) causes this, i.e. if CFLAGS has -mno-sse3 than ./configure should be called with -no-sse3. Probably some automatic detection of this could be added to qt4-build.eclass since qt-guys won't fix this (at least QTBUG-18688 closed as invalid)
(In reply to comment #4) > Probably some automatic detection of this could be added to qt4-build.eclass > since qt-guys won't fix this (at least QTBUG-18688 closed as invalid) Yes, that could be done. But why don't you use -march=native in your CXXFLAGS?
BTW, sse3 is called "pni" in /proc/cpuinfo, so you *do* have sse3 support.
(In reply to comment #6) > BTW, sse3 is called "pni" in /proc/cpuinfo, so you *do* have sse3 support. Thanks, I did not know that. I don't remember quite clear about -march=native. I think my CFLAGS is based on the info from the old gcc where no native option was available.
