Created attachment 471010 [details] emerge log After upgrading from sys-devel/gcc-4.9.4 to sys-devel/gcc-5.4.0-r3, I did : revdep-rebuild --library 'libstdc++.so.6' -- --exclude gcc but, kalarm (and kde-apps/kdepim-common-libs but didn't investigate about it) doesn't compile anymore. Tried with FEATURES="-distcc" then MAKEOPTS="-j1".

Apparently you didn't rebuild dev-libs/xapian as part of the big revdep-rebuild, or it failed to build.
Yes I did # genlop -i xapian * dev-libs/xapian Total builds: 9 Global build time: 17 minutes and 40 seconds. Average merge time: 1 minute and 57 seconds. Info about currently installed ebuild: * dev-libs/xapian-1.2.24 Install date: Thu Apr 27 13:13:08 2017 USE=" -doc -static-libs --cpu_flags_x86_sse -+cpu_flags_x86_sse2 -+brass -+chert -+inmemory" CFLAGS="-march=nocona -O2 -pipe CXXFLAGS="-march=nocona -O2 -pipe LDFLAGS="-Wl,-O1 -Wl,--as-needed" And revdep-rebuild doesn't give ANYTHING to compile.
Of course(In reply to Christophe PEREZ from comment #3) > And revdep-rebuild doesn't give ANYTHING to compile. Of course not, I assumed you are aware of the revdep-rebuild command required for the GCC-5 upgrade as described in the news item. Your build.log tells the opposite. Check `equery b /usr/lib64/libbaloopim.so.4` and rebuild that.

Check `equery b > /usr/lib64/libbaloopim.so.4` and rebuild that. baloo, and I compiled 100 times. But no problem, forget it.

Also, just in case kdepim-common-libs was not rebuilt, do that manually as well.
...and disable ccache.
