STINNER Victor <vstin...@python.org> added the comment:
Oh! I managed to build a static Python with the following commands:
cd /opt/pymaster/lib/python3.10/config-3.10-x86_64-linux-gnu
gcc -static -o ~/python-static python.o -L. $(./python-config.py --libs --embed)
I get a static binary:
$ ldd ~/python-static
not a dynamic executable
And it works as expected:
$ ~/python-static
Python 3.10.0a2+ (heads/master:1f73c320e2, Nov 10 2020, 11:47:55)
[GCC 10.2.1 20201016 (Red Hat 10.2.1-6)] on linux
Type "help", "copyright", "credits" or "license" for more information.

But... does any user really build Python manually after Python is installed?
The Python build system couldn't handle that as part of the regular build?
Maybe using a new configure --enable-static flag?
I'm not a fan of static binaries. For example, the linker emits many warnings
about static linking:
