            Bug ID: 113177
           Summary: GCC 8.5.0 build with libstdcxx gets library versions
                    mixed up
           Product: gcc
           Version: 8.5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: eyalroz1 at gmx dot com
  Target Milestone: ---

If I try to build GCC versions 8.5.0, or 6.5.0, on a recent GNU/Linux
distribution, e.g. Devuan Excalibur (~=3D Debian Trixie), with the following
config:

./configure  --enable-languages=3Dc,c++

at some point in the build, I get:

libstdc++.so.6: version `GLIBCXX_3.4.30' not found

and it seems like the build either tries to use the host system's libstdc++=
, or
otherwise mixes up the versions of things it's using.=
