Embedding Lua in C/C++ (1 Viewer)

I'm following @stetre's amazing guide (link to guide) on how to embed Lua in C/C++

• Lua version: 5.3
• Operating system: Ubuntu 20.04 LTS

These are the additional steps I had to take to get it to work:

Note: I'm a complete beginner, and it may be obvious to more experienced Lua developers, but I'm posting some of the additional steps I had to take just in case others experience the same problem.

I got

main.c:2:10: fatal error: lua.h: No such file or directory
    2 | #include <lua.h>
      |          ^~~~~~~
compilation terminated.

when I tried to compile the program with

cc -o myapp main.c -llua -lm -ldl

The solution was to install liblua5.3-dev (apt-get install liblua5.3-dev) and specify the Lua version when including the headers like this:

#include <lua5.3/lua.h>
#include <lua5.3/lualib.h>
#include <lua5.3/lauxlib.h>

Then I got another error:

/usr/bin/ld: cannot find -llua
collect2: error: ld returned 1 exit status

Same problem, I had to add the version explicitly:

cc -o myapp main.c -llua5.3 -lm -ldl

It compiled and I was able to run the script.

Hi, check out Sol3. It's an amazing binging library for Lua/C++. Cross platform.

I have two articles on using it on Windows, but the code would be the same:

Lua, Sol 3 and C++ (Oh, My!) : Part 1 - Nice Doggy. I've seen a couple of questions now about embedding Lua in C++. While it is certainly possible to use the C API in C++, I wanted to introduce a pure C++ interface to Lua called Sol 3. Sol3 is a template based approach to Lua. It is...
