Statically linking libstdc++ in terms of the license is fine. It is available with the GCC Runtime Library Exception: https://gcc.gnu.org/onlinedocs/libstdc++/manual/license.html > PEP 513 clearly says: > > GCC <= 4.2.0 > > > This excludes GCC 4.1. > > > 4.1 <= 4.2, so it’s included. This excludes GCC 4.1 from being a requirement. GCC 4.2 would work.
