xml install fail

[dauuricus]

i can't install xml on Termux luarocks.

Installing https://luarocks.org/lua-requests-1.2-2.src.rock

You may have to install STDCPP in your system and/or pass STDCPP_DIR or STDCPP_LIBDIR to the luarocks command.

Example: luarocks install xml STDCPP_DIR=/usr/local

termux has no stdc++
termux/termux-app#1846

I want to 'redirect' function on https, but i can't do in luasec.So I really want to know how to redirect https request on Lua lang programming.

I have no knowledge about c++ environment and luarocks recipe , so I tripped. I want to know how to make lua xml on termux or how to build lua xml except for using 'STDCPP'.

this is not good solution.
