Installation through package manager

Arch Linux

The package lua-pam-git can be installed from the Arch Linux User Repository using the following command. The command assumes your package manager is yay.

yay -S lua-pam-git

The file liblua_pam.so is installed into /usr/lib/lua-pam/.

Usage

-- add the lib to cpath by yourself

local pam = require("liblua_pam")
local auth = pam.auth_current_user(password)

if auth
then
    print("Success!")
end

Troubleshooting

cannot find -llua

Check for lua libraries in /usr/lib. If a library exists like liblua5.4.so or libluajit-5.1.so, change lua in CMakeLists.txt to use the library you have installed (in the example libraries before, this would be lua5.4 and luajit-5.1 respectively).

cannot find lua.hpp

Make sure that lua.hpp exists on your machine, and then create a soft link to the /usr/include directory if it isn't there already. You can change CMakeLists.txt to include your own directory which contains lua.hpp.

cannot find liblua.so

Make sure the file exists on your machine. A package will need to be installed on some distros. For distros such as Debian/Ubuntu, you should install liblua-dev.

cannot find pam_appl.hpp on Ubuntu/Debian

Install libpam0g-dev.
