How To Configure Shebang Line Of Internal Python Tools

I am trying to build a minimal docker image, capable of nothing more but running the Python interpreter. During development I start from alpine, the final image will be build FROM

Solution 1:

A common convention in Autoconf-based build systems is to support a Make variable DESTDIR. When you run make install, if DESTDIR is set, it actually installs into the configured directory under DESTDIR, but still built with the original path. You can then create an archive of the target directory, or in a Docker context, use that directory as the build context.

cd Python-3.8.7
# Use the final install target as the --prefix
./configure --prefix=/python
# Installs into e.g. ../python/python/bin/python3.8
make install DESTDIR=../python

cd ../python
tar cvzf ../python.tar.gz .

You can see this variable referenced in the Python Makefile in many places.
