Generating StrictDoc to a static binary: Experiences so far

[stanislaw]

Using Nuitka to generate a StrictDoc static binary is a great idea, however it looks like some extra work has to be done before the whole build pipeline produces executables valid on all platforms.

Observations so far:

• It was relatively easy to create an initial script that collects all modules and their data files: https://github.com/strictdoc-project/strictdoc/pull/841/files#diff-2e746c9eacad6e2c2fdefdc6a665b5ce4607ea384ebf97a729044b79acc778d6R560
• The whole build process is rather long (15+ minutes)
• The incremental process does not work for Python. If you change a single character in StrictDoc's codebase, the whole process is repeated again.
• I was building with --static-libpython=no because my pyenv-created Python versions do not allow the static build. When I run the nuitka-built binary for the first time on macOS, the warm up time takes up to 20+ seconds which is extremely long. Starting from the second run, however, the binary StrictDoc works much faster than the Python version. I am assuming that the startup time will change when compiled with --static-libpython=yes.

Below I am sharing the problems that I have encountered on macOS. The segmentation fault problem below is the most prominent so far, and I don't know how to fix it quickly. With more time, I would reach out to the Nuitka developers and ask them how the call stacks like the one below can be investigated (the call stack goes around bibtex).
