midimonster: Lua interpreter extensions may fail to load if not linked against liblua themselves

My config wont parse because it gets this:

Failed to load source file fsgc2ir.lua for instance gc: error loading module 'socket.core' from file '/usr/lib/arm-linux-gnueabihf/lua/5.3/socket/core.so':
	/usr/lib/arm-linux-gnueabihf/lua/5.3/socket/core.so: undefined symbol: lua_gettop

Running Raspberry Pi4 with Raspbian latest. Aim is to use TouchOSC to control multiple aspects of my studio I have lua 5.1, 5.2 and 5.3 installed as well as luasocket library. Is there any other libraries I need? I tried installing the socket library with luarocks but it comes up with this error:

pi@raspberrypi:~ $ sudo luarocks install luasocket
Installing https://luarocks.org/luasocket-3.0rc1-2.src.rock
gcc -O2 -fPIC -I/usr/include/lua5.1 -c src/mime.c -o src/mime.o -DLUA_COMPAT_APIINTCASTS -DLUASOCKET_DEBUG -DLUASOCKET_API=__attribute__((visibility("default"))) -DUNIX_API=__attribute__((visibility("default"))) -DMIME_API=__attribute__((visibility("default")))
src/mime.c:7:10: fatal error: lua.h: No such file or directory
 #include "lua.h"
          ^~~~~~~
compilation terminated.

Error: Build error: Failed compiling object src/mime.o

so I installed all the libraries the standard way including socket:

sudo apt-get install luasocket
sudo apt-get install luasocket-dev

For your specific use case, an example config using Python might be as follows (this just maps my mouse keys to two commands, but you get the picture)

globalcache.cfg

[python gc]
module = globalcache

[evdev in]
input = TPPS

[map]
in.EV_KEY.BTN_LEFT > gc.globalcache.input1
in.EV_KEY.BTN_RIGHT > gc.globalcache.input2

globalcache.py

import socket
import midimonster

DEVICE_IP="127.0.0.1"
DEVICE_PORT=4998

def socket_handler(sock):
	data = sock.recv(1024)
	print("Received %d bytes from socket: %s" % (len(data), data))
	if(len(data) == 0):
		# Unmanage the socket if it has been closed
		print("Remote has closed the connection")
		midimonster.manage(None, sock)
		sock.close()

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((DEVICE_IP, DEVICE_PORT))
midimonster.manage(socket_handler, s)

def input1(value):
	if value > 0.9:
		s.send(bytes("sendir,1:1,0,38000,1,1,341,170,21,21,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,64,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,21,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,1517,341,85,21,3655\r", "utf-8"))

def input2(value):
	if value > 0.9:
		s.send(bytes("sendir,1:1,0,38000,1,1,341,170,21,21,21,21,21,21,21,64,21,21,21,21,21,21,21,21,21,64,21,64,21,64,21,21,21,64,21,64,21,64,21,64,21,21,21,21,21,64,21,21,21,64,21,21,21,64,21,21,21,64,21,64,21,21,21,64,21,21,21,64,21,21,21,64,21,1517,341,85,21,3655\r", "utf-8"))
