Running Ruby in C

I’m trying to run a block of Ruby code inside a C program.

I have the following code:

#include <ruby.h>

int main(int argc, char* argv[])
{
    /* Construct the VM */
    ruby_init();

    /* Ruby goes here */

    /* Destruct the VM */
    return ruby_cleanup(0);
}

But when I try to run the program, I get the following error:

fatal error: ruby.h: No such file or directory

#include <ruby.h>

I read that it is needed to tell the compiler about the include paths for the required headers with the following code in Ubuntu:

pkg-config --cflags --libs ruby-2.5

gcc -I/usr/include/ruby-2.5.0 -I/usr/include/ruby-2.5.0/x86_64-linux -lruby

I have already done that, but the problem isn’t solved.

Follow the steps in How can I include a needed C library using GCC?.

I don't understand the difference between the two -l, but try to follow the following structure. If I'm right, your command will be like:

gcc -I/usr/include/ruby-2.5.0 -L/usr/include/ruby-2.5.0/x86_64-linux -lruby

Where:

-I <searchpath to include files>
-L <searchpath to the lib file>
-l <thelibname>

I don't know if the library is the first or the second parameter, but you can check it.
