--- Comment #6 from Mysaa <samyavrillon at netcourrier dot com> ---
So I ran the compilation adding only --enable-multiarch and it failed with
nother error :
cp ../../gcc/../fixincludes/README-fixinc include-fixed/README
chmod a+r include-fixed/README
echo timestamp > stmp-int-hdrs
/home/bernard/building/gcc-9.2.0/build/./gcc/xgcc

/dev/null -fself-test=../../gcc/testsuite/selftests

/dev/null -fself-test=../../gcc/testsuite/selftests
xgcc: fatal error: cannot execute 'cc1plus': execvp: No such file or directory
compilation terminated.
../../gcc/cp/Make-lang.in:178: recipe for target 's-selftest-c++' failed


Nonetheless, I found the compilation options gcc6 was originally compiled with
and ran the sams ctring (disableing some options) and the make process and the
make install processes completed. But the make check failed. I send you the
./configure line and the error of make check :

It's strange as i see no specific test failing
