I have a newly installed Fedora 40 install on my laptop. I’ve downloaded version 3.12.4 from python website. I run the following:

./configure --prefix=/opt/python/3.12.4/ --enable-optimizations --without-ensurepip --enable-ipv6 --enable-shared

In the same folder of the build I then run:

make -j `nproc`

And then in the same folder I run

./python --version

and I get the strange result

Python 3.12.3

But I’m building 3.12.4

If I remove the configure option --enable-shared and redo the build

./configure --prefix=/opt/python/3.12.4/ --enable-optimizations --without-ensurepip --enable-ipv6

In the same folder of the build I then run:

make -j `nproc`

And then in the same folder I run

./python --version

I now get the right version

Python 3.12.4

Fedora 40 native system python version is 3.12.3

Why is this occurring?
