is compiled python file under debian is compatible with ubuntu

Question

I'm using nuitka to compile my python codes. I use --module option to import my code inside other python files:

nuitka --module --recurse-none file.py
Output: file.so

If I don't need to import the code and just need to run on terminal, I'm following regular compiling process:

nuitka --recurse-none file.py
Output: file.exe

I'm compiling these files under Debian and they work without a problem under Debian. When I move these files to an Ubuntu system, I sometimes get Segmentation Fault errors. Is it because a compiled python code under Debian is not compatible with Ubuntu or am I doing a personal mistake (like missing library etc.)

Answer 1

As answered by abarnert, if you want to make your executable independent from the specific python installation on your device, you need to use the --standalone option.

You can check that info in the Nuitka Manual

Answer 2

Dynamic Linking

From the docs,

It translates the Python into a C level program that then uses "libpython" to execute in the same way as CPython does.

Do you have libpython installed and pointing to the same version as the one you are compiling from? Example, on arch:

$ whereis libpython
libpython: /usr/lib/libpython3.so

Shows I have libpython installed and belonging to python 3.x (notice 3 at end of path).

Static linking.

The other way to do is I guess as suggested by others, i.e, using --standalone option. This should avoid the need of libpython
