Do you have an example file ready to compile pls?

[noeldum]

I landed here and gave it a try with the example provided. First it complained of many include missing. I had to add these below to parser.h

#include <cstdio>
#include <cstddef>
#include <cstdlib>
#include <cstring>

Does it makes sense?

Now I am stuck with the compilation error below.

In file included from config_reader.cpp:1:
parser.h: In function ‘config_option* read_config_file(char*)’:
