we have old Linux distribution and the vendor doesn't support its updates. We want to build our c++ code with a modern compiler, for that we are building GCC compiler from sources (something very similar to https://github.com/darrenjs/howto/blob/master/build_scripts/build_gcc_10.sh)
Now the problem is that we can not deploy the executables because users' machine do not contain libstdc++.so.6 for this GLIBC. Is there a way to compile GCC and make it based on old local GLIBC that the vendor provides?
[EDIT]: After build my executable of xenenterprise 8.0.0 with GCC 10.1.0 that was built from sources:
