Subject: install-deps.sh: use gcc-12 for ubuntu jammy
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=0f3b651fcc1736cf484ca9881ba36985ea87242d;p=ceph.git

install-deps.sh: use gcc-12 for ubuntu jammy

Clang relies on the system's libstdc++ headers for standard C++
features. On Ubuntu Jammy, gcc-11 is the default and it's libstdc++ is
missing some of the newer features supported by C++20.

This causes build failures as certain standard headers are incomplete.
To fix this, we install gcc-12 explicitly so that Clang can pick up the
newer libstdc++ headers.
