Error: LuaRocks 3.11.0 bug - win32-x86_64 (fs_use_modules = true) (binary) - when installing a package that transitively depends on LuaFileSystem

[mrcjkb]

Please fill out the following:

• Platform:

  • win32-x86_64

• LuaRocks version:

  • 3.11.0

• Configuration file:

  • Default config

• LuaRocks output from when the issue occurred:

https://gist.github.com/mrcjkb/ce8dfe66b4eff37092ca5bd396b193f9

(includes both verbose and non-verbose output)

• Description:
  • Run on a Windows GitHub runner with this workflow file.
  • Trying to install a package, which has a build dependency, luarocks-build-treesitter-parser, which depends on LuaFileSystem.
  • For some reason, it seems to be looking for a lua 5.4 header, even though it's configured to install with lua 5.1;
    see this log line: Build error: Lua header lua.h found at D:/a/rocks-binaries-dev/rocks-binaries-dev/.lua/include does not match Lua version 5.4.

This is because the LuaRocks binary itself is built with Lua 5.4, so the build dependency refers to the version LuaRocks itself is running in, not the Lua version that LuaRocks is targeting.

So, to clarify, I do not consider this to be a bug per se. But I do realize this makes the CI setup awkward, especially on Windows where multiversion packages are not common. I don't have an immediate suggestion on how to best deal with this... this is worth thinking about.

Ah, thanks for the clarification 😄
