Hi

it would be nice only send mails to the list because you break threading....

why does MariaDB use "-g -static-libgcc" in "mysql_release.cmake" and so
besides override -g0 break -flto builds?

I think you might be misunderstanding the purpose of mysql_release.cmake
it is there to simplify the build of release packages, for us. If you
want to build exactly like our release package are build,  use

thanks for the hint, years ago i forked the rpm-spec from Fedora,removed that now

cmake  <path-to-source> -DBUILD_CONFIG=mysql_release
make package

If you want something special, do not use it.

cmake <path-to-source>
make package

This provides a good baseline (builds with RelWithDebInfo build type,
i.e optimized with debug info)
you can add your flags on top of that

sorry but no - it don't provide a good baseline at all setting -O3unconditional and the why you removed from your quotes


anyways, it still overrides and -flto fails

"-fstack-protector --param=ssp-buffer-size=4 -fno-exceptions -fno-rtti-O2 -g" is not supposed to be here the build below was with"-DWITH_PIC=NO" and with "-DWITH_PIC=YES" you can see even a lot oflto-mismatch-errors before the build breaks as i tried also switch to-O2 in general with no success for -flto
