Rlua + Luarocks Modules -> Fail to load about rlua HOT 3 CLOSED

Glad to be able to help!

Hi,
It looks like you've configured rlua with the default "builtin-lua54", but are trying to use luarocks installed with Lua 5.3.
To use the system-installed Lua 5.3 library instead, specify the dependency liks this in Cargo.toml:

rlua = { version = "0.19", default-features = false, features=["system-lua53"] }

Second, by default rlua disables C extensions for safety. lrand is a C extension so that needs enabling. Instead of Lua::new, you can use Lua::unsafe_new_with_flags:

let lua = unsafe { Lua::unsafe_new_with_flags(rlua::StdLib::ALL, rlua::InitFlags::NONE) };

Depending on your luarocks or Lua installations, you may also need to add the luarocks path to package.cpath, but I didn't need to do that on my Ubuntu 22.04 system with luarocks installed from the Ubuntu package.

Putting it together, this worked for me: https://github.com/jugglerchris/rlua_luarocks_lrand

rlua_luarocks_lrand$ luarocks-5.3 list

It is so good to get solutions from expertise rather than searching for days and trying ChatGPT capabilities.

Thanks, it solved the problem!
