I ran into this issue as well. After some digging, I found out how to send CXXLAGS flags to the compiler to tell it to run in C++14 mode by updating the .rockspec file. The updated .rockspec file can be found here: https://gist.github.com/ossie-git/ffddb4fd619c93db6baa45b62a65b89b which compiles on newer distributions (including Ubuntu 22.04). Below is a local copy if you prefer to copy/paste:

    This module is part of the Lubyk project.

    Main features are:
     - Fast and easy to use
     - Complete documentation
     - Based on proven code (RapidXML)
     - Full test coverage

After this solution for installing lua-requests (Debian 12, lua 5.3) i'v got the next:

[ERR] mod_lua.cpp:202 /usr/local/share/lua/5.3/requests.lua:8: module 'xml' not found:
        no field package.preload['xml']
        no file '/usr/local/share/lua/5.3/xml.lua'
        no file '/usr/local/lib/lua/5.3/xml.so'
stack traceback:
        [C]: in function 'require'
        /usr/local/share/lua/5.3/requests.lua:8: in main chunk
        [C]: in function 'require'
        [string "line"]:1: in main chunk

I tried this way:

apt-get install libssl-dev
luarocks install luasec
cd /usr/src
git clone https://github.com/lubyk/xml xml_lua
git clone https://gist.github.com/ossie-git/ffddb4fd619c93db6baa45b62a65b89b rockspec
cp /usr/src/rockspec/xml-1.1.3-1.rockspec /usr/src/xml_lua/xml-1.1.3-1.rockspec
cd /usr/src/xml_lua
luarocks install xml-1.1.3-1.rockspec
luarocks install lua-requests

Where is my mistake?
