Installing lcomplex on Lua 5.3

[Aditya Mahajan <adityam@...>]

Hi,

I am trying to install lcomplex on Lua 5.3 using

  $luarocks install lcomplex --local

which gives

Installing https://luarocks.org/lcomplex-20120430-1.src.rock

gcc -O2 -fPIC -I/usr/include -c lcomplex.c -o lcomplex.o
lcomplex.c: In function ‘luaopen_complex’:
lcomplex.c:155:2: warning: implicit declaration of function ‘luaL_register’; 
did you mean ‘lua_register’? [-Wimplicit-function-declaration]
  luaL_register(L,MYNAME,R);
  ^~~~~~~~~~~~~
  lua_register
gcc -shared -o complex.so lcomplex.o
lcomplex 20120430-1 is now installed in /home/adityam/.luarocks (license: 
MIT/X11)

The library gets installed but when I try to use it, I get the error (as 
expected)

  $lua -lcomplex

which gives

lua: error loading module 'complex' from file 
'/home/adityam/.luarocks/lib/lua/5.3/complex.so':
        /home/adityam/.luarocks/lib/lua/5.3/complex.so: undefined symbol: 
luaL_register
stack traceback:
        [C]: in ?
        [C]: in function 'require'
        [C]: in ?


Any hints on how to fix this?

Thanks,
Aditya
