Tech/HowTo/Python Freeze

About

How to make a portable binary out of some Python code. Us Python Freeze which is part of the core Python Project

Requirements

Some Python packages put the freeze.py in the pythonX-examples package and you will also need the libz-dev package.

A library may need linked

ln -s /usr/lib/x86_64-linux-gnu/libpython3.9.so /usr/lib/libpython3.9.so

Example

Playing with my protocols package I gave it a try (I had to manually disable a call to __file__)

• https://lathama.net/git/lathama/protocols/src/branch/master/python/example.py

Normal:

python3 example.py
NTP server serving on 127.0.0.1 at port 8123
Query NTP for time and report in ISO8601 format
2020-08-14 07:40:10
NTP server is currently Off

Compile and run as binary

mkdir tmp
python3 /usr/share/doc/python3.9/examples/freeze/freeze.py -X codecs -X copy -X distutils -X encodings -X locale -X pydoc -X warnings -o tmp example.py -m protocols
cd tmp
make
./example
