You just add the -static argument, if you want a fully static executable that can run on any linux distro: ‘g++ -o main main.cpp -static’

You can even go above and beyond with cosmopolitan libc v2, which makes c/c++ build-once run-anywhere: https://github.com/jart/cosmopolitan/releases/tag/2.0

There seems to be some work getting cosmopolitan libc support in Go, but it is not ready like it is for c/c++: https://github.com/golang/go/issues/51900

Edit: There can be some problems with using static, if you are using your system package manager for library dependencies. I would recommend compiling dependencies from source using CMake and FetchContent, this has solved pretty much all problems I have had with c++ dependency management.
