(See also bug 541612.) The 32-bit build (multilib) on AMD64 fails with the below error message during emerge. I've rebuild all installed dev-qt/*:4 packages to make sure there's nothing wrong with them, but it doesn't help: /usr/bin/x86_64-pc-linux-gnu-g++ -fPIC -pipe -mtune=native -march=native -O2 -fomit-frame-pointer -floop-interchange -floop-strip-mine -floop-block -DQT_NO_CAST_FROM_ASCII -DQT_NO_CAST_TO_ASCII -Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu -Wl,--sort-common -shared -Wl,-soname,libqjson.so.0 -o ../lib/libqjson.so.0.8.1 CMakeFiles/qjson.dir/parser.cpp.o CMakeFiles/qjson.dir/qobjecthelper.cpp.o CMakeFiles/qjson.dir/json_scanner.cpp.o CMakeFiles/qjson.dir/json_parser.cc.o CMakeFiles/qjson.dir/parserrunnable.cpp.o CMakeFiles/qjson.dir/serializer.cpp.o CMakeFiles/qjson.dir/serializerrunnable.cpp.o CMakeFiles/qjson.dir/moc_parserrunnable.cxx.o CMakeFiles/qjson.dir/moc_serializerrunnable.cxx.o /usr/lib32/qt4/libQtCore.so -Wl,-rpath,/usr/lib32/qt4: /usr/lib32/qt4/libQtCore.so: error adding symbols: File in wrong format collect2: error: ld returned 1 exit status

$ emerge -pqv '=dev-libs/qjson-0.8.1-r1::gentoo' [ebuild U ] dev-libs/qjson-0.8.1-r1 [0.8.1] USE="-debug -doc {-test}" ABI_X86="32%* (64%*) (-x32)"
Created attachment 397654 [details] build.log
It's building ABI x86_32 without -m32, I'm not sure why.
I just noticed that this isn't included in the emerge --info output. I have this in my make.conf: CFLAGS_x86="${CFLAGS_x86} -march=native" For some reason this removes the -m32 flag even though "${CFLAGS_x86}" is still included in there. This and libdbusmenu-qt seem to be the only ebuilds that have that problem. Every other multilib ebuild on the system compiles fine and the -m32 flag is present :-/
You are not supposed to touch CFLAGS_x86, ever. That's some magic stuff that's used in profiles & multilib.eclass.
Oh, damn. Today I learned: don't touch CFLAGS_* :-O Sorry for the noise.
