lua-input's Issues

init.lua:31: bad argument #1 to 'func' (FILE* expected, got nil)

Hi,

tried this simple example:

local input = require("lua-input")

-- read events from a device
local input_dev = input.open_input("/dev/input/event3")
while true do
	local ev = input_dev:read_event()
	print("event",ev.type, ev.code, ev.value)
end

got the following error:

lua: /usr/local/share/lua/5.3/lua-input/init.lua:31: bad argument #1 to 'func' (FILE* expected, got nil)
stack traceback:
	[C]: in function 'input.read_event'
	/usr/local/share/lua/5.3/lua-input/init.lua:31: in method 'read_event'
	input-event3.lua:6: in main chunk
	[C]: in ?

error loading module 'input' from file '/usr/local/lib/lua/5.2/input.so'

Hi

Installed and cross compiled lua-input according to the Manual installation on this Linux system:

uname -a
Linux (none) 4.1.15-00838-g349fbf5767c #90 SMP PREEMPT Thu Sep 15 15:12:23 CST 2022 armv7l GNU/Linux

Start the Lua interpreter:

~ # lua
Lua 5.2.2  Copyright (C) 1994-2013 Lua.org, PUC-Rio
> local input = require("lua-input")
error loading module 'input' from file '/usr/local/lib/lua/5.2/input.so':
        dynamic libraries not enabled; check your Lua installation
stack traceback:
        [C]: in ?
        [C]: in function 'require'
        /usr/local/share/lua/5.2/lua-input/init.lua:1: in main chunk
        [C]: in function 'require'
        stdin:1: in main chunk
        [C]: in ?

Any hint to solve this problem?

BTW, it works fine on a Raspberry Pi (Linux 5.10)
