A quick try (with a simple -static on the link command) suggests glibc isn't too happy with static executables... I'd try to use another libc, e.g. dietlibc instead, but I don't think I will have time to have a look at that for a while.

Static binary will generate a kind of portable application, that can run into a distroless docker image.
It will be great 😄

This should work (source)?

-static-libgcc -static-libstdc++

I could not get to link libpcreposix.

I don't know how to tie them.
