was trying to reproduce #789 on a new machine and came across this

[mrcjkb]

This is an issue with the nix shell, not Lux. I've come across it too, but haven't figured out what's missing yet.

Just had the same issue:

➜ lx --lua-version 5.1 add lual

➜ lx --version
lux-cli 0.7.3

The library doesn't rely on gcc at all so I wonder why gcc seems to be invoked or searched for. Is it to find lua headers to try to compile a lua interpreter ?

[mrcjkb]

so I wonder why gcc seems to be invoked or searched for.

If Lux can't find Lua using pkg-config, it'll try to build it from source.

[cootshk]

I've run into the same issue again, trying to add luafilesystem on an alpine linux docker image. lx run runs fine without luafilesystem, and gcc is in my PATH.

[cootshk]

lx run output:

Error: syncing dependencies with the project lockfile failed.
