lua5.5 only: `python.so`: undefined symbol: `luaL_openlibs`

lua5.5 tests/test_py.lua # fails...

• GitHub Actions: Complete tests #94 runs lua tests/test_py.lua on Lua 5.1, 5.2, 5.3, 5.4, and 5.5 on Ubuntu 26.04.

The tests pass on lua5.1 and lua5.3 but fail on lua5.5 with:

lua5.5: error loading module 'python' from file './python.so':
	./python.so: undefined symbol: luaL_openlibs

Note

This comment goes for #98 and #99 as well

Hi :) Thanks for pointing this out!

The issues you've spotted can be resolved with Lua version specific #ifdefs.

I can implement that, but would propose to wait until #94 is merged, as this will be a good test for the Github Actions pipeline.

I know Python, but I am using this effort to learn a bit of Lua.

I agree that getting GHA running should happen before the fixes, so we have proof and can detect any future regressions.

oh, Nice :)

Lua is fun! The Lua C-API (which is what we primarily work with in lunatic-python) is a bit more complex, but generally Lua does not have a lot of syntax.

Let's implement the pipeline then and we can continue to these three issues. Should be quick to do!
