Trying to set CFLGAS/CXXFLAGS for this package does not work. Either in make.conf or in package.env. I installed my system using lto for all packages and I compile packages that fail because of lto using CXXFLGAS with no lto. Reproducible: Always Steps to Reproduce: 1. Set package.env or make.conf for this package to something like "CXXFLAGS=-O3" 2. emerge dev-qt/qtjsbackend:5 3. Build procedure will ignore CXXFLAGS and LDFLAGS set. 4. Recompile qtcore:5 with some new flags like "CXXFLAGS=-O3" 5. Remove the flags set for dev-qt/qtjsbackend:5 and set it to "CXXFLAGS=-Os" 6. Recompile dev-qt/qtjsbackend:5 and it will build with -O3
1) Please post your `emerge --info' output in a comment. 2) Please post your `emerge -vpq dev-qt/qtjsbackend' output in a comment. 3) Please attach the entire build log to this bug report.

portage/package.env/qt5: =dev-qt/qtjsbackend-5.0.1 safe-cflags.conf portage/env/safe-cflags.conf: CFLAGS="-O3 -pipe -march=native -fomit-frame-pointer" CXXFLAGS="${CFLAGS} -fpermissive" LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--hash-style=gnu"
Can you provide these configuration files as well? Portage should pass it right if you configured it right, I don't see how -fLTO would magically pop up there; it can happen, but very unlikely...
Ignore what I said, I didn't read all your comments so I missed the last one. You should use -fno-lto in your portage/env/safe-cflags.conf instead.
Let me make it clear that this is the only package I have that fails with the safe-cflags.conf that I have. Several other packages that fail due to LTO will compile just fine when I set their env in safe-cflags; for example dev-qt/qtwebkit:4.
Oh, I see, this is from the Qt overlay.
I have the same problem, but encountered in qtwebkit-5.1.0 - posting here, because it's most likely a common problem in qt5-build.eclass. In my case, I have -ggdb in make.conf and then use package.env to disable debug symbols for packages where it would require excessive amounts of memory to compile: $ cat /etc/portage/env/nodebug CFLAGS="${CFLAGS} -g0" CXXFLAGS="${CXXFLAGS} -g0" qt5-build.eclass even has this warning - however with this bug the user can no longer follow the advice if [[ ${PN} == "qtwebkit" ]]; then eshopts_push -s extglob if is-flagq '-g?(gdb)?([1-9])'; then echo ewarn "You have enabled debug info (probably have -g or -ggdb in your CFLAGS/CXXFLAGS)." ewarn "You may experience really long compilation times and/or increased memory usage." ewarn "If compilation fails, please try removing -g/-ggdb before reporting a bug." ewarn "For more info check out https://bugs.gentoo.org/307861" echo fi eshopts_pop fi It look like user-defined flags from /etc/make.conf *are* used for qtwebkit, but not from the time qtwebkit is compiled. Instead, they are hardcoded at the time qtcore is emerged: $ qlist qtcore | xargs grep amdfam10 /usr/lib64/qt5/mkspecs/qmodule.pri:QMAKE_CFLAGS = -O2 -pipe -O2 -march=amdfam10 -ggdb -pipe /usr/lib64/qt5/mkspecs/qmodule.pri:QMAKE_CXXFLAGS = -O2 -pipe -O2 -march=amdfam10 -ggdb -pipe This is really confusing behavior - hopefully it will be fixed before Qt 5 is merged to the tree.
qtjsbackend is going to die soon (it's not used anymore since 5.2)
