If I go into $WORKDIR manually and add -mavx -mavx2 in /var/tmp/portage/dev-qt/qtmultimedia-5.6.2/work/qtmultimedia-opensource-src-5.6.2/src/multimedia/Makefile Then it builds just fine. Why *isn't* a full rebuild of QT from -core up - apparently not honouring CFLAGS

Can you attach the build log for qtcore please?

It may also be useful to mention - I have most of QT4 installed - it seems to exhibit the same behaviour with CFLAGS in qtmultimedia - but not qtcore. (However here qtmultimedia:4 builds fine) (This was a rebuild of dev-qt/*:4 from yesterday whilst I was trying to isolate the issue.) # ls -ltr *qtmultimedia-4.8.7* -rw-rw---- 1 portage portage 3584 Oct 15 13:09 dev-qt:qtmultimedia-4.8.7:20161015-120920.log -rw-rw---- 1 portage portage 447094 Oct 15 13:09 dev-qt:qtmultimedia-4.8.7:20161015-120747.log # grep march dev-qt:qtmultimedia-4.8.7:20161015-120747.log | tail -n 1 x86_64-pc-linux-gnu-g++ -c -O2 -pipe -march=core2 -msse4 -mcx16 -msahf -msse4.1 -msse4.2 -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -D_REENTRANT -fPIC -DQT_SHARED -DQT_BUILD_MULTIMEDIA_LIB -DQT_NO_USING_NAMESPACE -DQT_NO_CAST_TO_ASCII -DQT_ASCII_CAST_WARNINGS -DQT_MOC_COMPAT -DQT_USE_QSTRINGBUILDER -DHAS_ALSA -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_HAVE_SSE3 -DQT_HAVE_SSSE3 -DQT_HAVE_SSE4_1 -DQT_HAVE_SSE4_2 -DQT_HAVE_AVX -D_LARGEFILE64_SOURCE -D_LARGEFILE_SOURCE -I/var/tmp/portage/dev-qt/qtmultimedia-4.8.7/work/qt-everywhere-opensource-src-4.8.7/mkspecs/linux-g++ -I/var/tmp/portage/dev-qt/qtmultimedia-4.8.7/work/qt-everywhere-opensource-src-4.8.7/src/multimedia -I../../include/QtCore -I../../include/QtGui -I../../include -I../../include/QtMultimedia -I.rcc/release-shared -I/var/tmp/portage/dev-qt/qtmultimedia-4.8.7/work/qt-everywhere-opensource-src-4.8.7/src/multimedia/video -I.moc/release-shared -I. -o .obj/release-shared/qaudioformat.o /var/tmp/portage/dev-qt/qtmultimedia-4.8.7/work/qt-everywhere-opensource-src-4.8.7/src/multimedia/audio/qaudioformat.cpp # ls -ltr *qtcore-4.8.7* -rw-rw---- 1 portage portage 106039 Oct 15 12:59 dev-qt:qtcore-4.8.7-r2:20161015-115952.log -rw-rw---- 1 portage portage 1463519 Oct 15 12:59 dev-qt:qtcore-4.8.7-r2:20161015-115651.log # grep march dev-qt:qtcore-4.8.7-r2:20161015-115651.log | tail -n 1 x86_64-pc-linux-gnu-g++ -c -O2 -pipe -ggdb -march=native -Wall -W -D_REENTRANT -DPROEVALUATOR_CUMULATIVE -DPROEVALUATOR_INIT_PROPS -DQT_NO_CAST_TO_ASCII -DQT_NO_CAST_FROM_ASCII -DQT_NO_DEBUG -DQT_XML_LIB -DQT_CORE_LIB -DQT_HAVE_MMX -DQT_HAVE_3DNOW -DQT_HAVE_SSE -DQT_HAVE_MMXEXT -DQT_HAVE_SSE2 -DQT_HAVE_SSE3 -DQT_HAVE_SSSE3 -DQT_HAVE_SSE4_1 -DQT_HAVE_SSE4_2 -DQT_HAVE_AVX -D_LARGEFILE64_SOURCE -D_LARGEFILE_SOURCE -DQT_SHARED -I/var/tmp/portage/dev-qt/qtcore-4.8.7-r2/work/qt-everywhere-opensource-src-4.8.7/mkspecs/linux-g++ -I/var/tmp/portage/dev-qt/qtcore-4.8.7-r2/work/qt-everywhere-opensource-src-4.8.7/tools/linguist/lupdate -I../../../include/QtCore -I../../../include/QtXml -I../../../include -I/var/tmp/portage/dev-qt/qtcore-4.8.7-r2/work/qt-everywhere-opensource-src-4.8.7/tools/linguist/shared -I/var/tmp/portage/dev-qt/qtcore-4.8.7-r2/work/qt-everywhere-opensource-src-4.8.7/src/declarative/qml/parser -I/var/tmp/portage/dev-qt/qtcore-4.8.7-r2/work/qt-everywhere-opensource-src-4.8.7/src/declarative/qml -I../../../include/QtDeclarative -I.moc/release-shared -I. -o .obj/release-shared/ui.o /var/tmp/portage/dev-qt/qtcore-4.8.7-r2/work/qt-everywhere-opensource-src-4.8.7/tools/linguist/lupdate/ui.cpp
I am a massive dick... (don't ask me how much of littering qtmm and a test dummy e-build with 'echo ${CFLAGS}' it took before I figured this out...) # grep -R qtmultimedia /etc/portage/ /etc/portage/package.env/origstuff.env:dev-qt/qtmultimedia nodebug # cat /etc/portage/env/nodebug CFLAGS="-O2 -pipe -march=core2 -msse4 -mcx16 -msahf -msse4.1 -msse4.2" CXXFLAGS="${CFLAGS}" Gah - leftovers from not wanting to bloat my rootfs with QT's debug symbols. Closing, please accept my sincere apologies for the time-waste.
No worries. Glad you quickly identified the root cause :)
