Impossible to say why this fails. Most steps seem to have worked: it built correctly, it imported, it (apparently) loaded the shared LuaJIT library - and then fails trying to initialise the LuaJIT runtime. Lua(JIT) doesn't provide any information at this point why it failed, so there isn't much of a way to make Lupa provide debug information here.
Does LuaJIT itself run on your machine?

That seems to be a newer version than I tried before. However, the problem is still the same.

This might give a hint:

Can you try building only for 64 bits by setting ARCHFLAGS="-arch x86_64" ?
You're using a 64 bit Python, right?

ISTM that in your last build attempt it didn't rebuild LuaJIT, just Lupa itself. Could you try a completely clean build with 64bit archflags?

You're running into this issue (documented http://luajit.org/install.html):
"If you're building a 64 bit application on OSX which links directly or indirectly against LuaJIT, you need to link your main executable with these flags:
-pagezero_size 10000 -image_base 100000000
Also, it's recommended to rebase all (self-compiled) shared libraries which are loaded at runtime on OSX/x64 (e.g. C extension modules for Lua). See: man rebase"
Save yourself a lot of headaches and build lupa against lua51 instead.

Rebase does not seem to make a difference.
( command rebase -low_address 10000 -high_address 100010000 _lupa.so )
How do I instruct pip/setuptools to build lupa against lua51?

dubois
commented on August 30, 2024
The executable itself (python) must be linked with those flags. That's why
it's a pain in the butt.

Oh, and lupa 0.21 now comes with a setup.py flag "--no-luajit" (if I
remember correctly). For 0.20, hacking setup.py also works.

Closing as this is an issue with the user local setup. When built properly, it shouldn't occur. I'd accept pull requests that make the build more robust, though.
