i simply removed -flto since it don't work attached the RPM SPEC file %{optflags} translates to .rpmrc [builduser@testserver:~]$ cat .rpmrc optflags: x86_64 -m64 -O2 -g0 -march=sandybridge -mtune=sandybridge -fopenmp -mfpmath=sse -pipe -fno-strict-aliasing -fomit-frame-pointer -finline-functions -finline-limit=60 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=6 -D_FORTIFY_SOURCE=2 -Wstack-protector -Wformat -Werror=format-security Am 01.10.2015 um 19:26 schrieb Sergei Golubchik:

"-O3 -g" appears in the cmake output, that likely breaks ld.gold / -flto and so the question: who the explain the build *not* add that useless param for production builds like most oterh software don't
without one could also remove the strip-calls in rpm-spec-files!
Sorry, I have more questions that answers...
* How do you build?

But you cannot be building this this line, right? You invoke cmake, somehow, and make, somehow. How? And may be you set CXXFLAGS and I don't know what else.
Where do you see -O3 -g?
the " -fPIC -O3 -g -static-libgcc" stuff comes *after* my global CFLAGS and so overrides them
Okay, that's better. "static-libgcc" is only used in two files in the source tree: ./BUILD/compile-bintar and ./cmake/build_configurations/mysql_release.cmake
So, either you're using BUILD/compile-bintar script (which I find unlikely) or you're invoking cmake with -DBUILD_CONFIG=mysql_release (which I find likely - and that's exactly why I was asking "how do you build" !)
This is not configurable, you cannot switch a part of mysql_release.cmake off. Either you use -DBUILD_CONFIG=mysql_release or you don't. If you don't like it - you can simply add all options from it manually to your CFLAGS and then you won't need -DBUILD_CONFIG
But you said it conflicts with -flto. Where does -flto come from? I don't see it in your CFLAGS. Nor is it on the compiler's command line below:
