Description
As discussed on slack with and discourse ( https://discourse.julialang.org/t/glibcxx-3-4-26-not-found-in-rcall/29113/2 ) the problem of an outdated, bundled libstdc++ (e.g. Julia 1.3.1) compared to the libstdc++ provided by the OS (e.g. Ubuntu 19.10) is that it breaks RCall.jl when Rcpp is in play due to missing GLIBCXX symbols.
I quote @staticfloat
So Ubuntu 19.10 is based on GCC 9, huh. We don't have a GCC 9 shard yet; we've been using GCC 7.2 on the buildbots (which correspondes to GLIBCXX_3.4.24), but there's no reason why we can't put our own libstdc++.so.6 into a julia binary-dist. Right now we've been bundling the libstdc++.so.6 that we get from the build environment, but it would be even better for us to just use an appropriate CompilerSupportLibraries_jll release, and craft those releases to be as compatible as possible (e.g. use the absolute newest libstdc++.so.6, the appropriate libgfortran.so.X, etc...)
An intermediate workaround is described here: https://discourse.julialang.org/t/glibcxx-3-4-26-not-found-in-rcall/29113/11?u=laborg
