Compiling ruby script to C

[Sjeanpierre]

I'm trying to follow this blog post from 2012 on compiling to C but ran into some issues.
http://blog.mruby.sh/201207020720.html

are there any current instructions on compiling a ruby script to C using mruby?

first I am running
mruby/bin/mrbc -Btest_symbol test_program.rb

When I run gcc -Imruby/src -Imruby/include -c test_program.c -o test_program.o i get the following error
test_program.c: In function ‘main’:
test_program.c:24: warning: implicit declaration of function ‘mrb_read_irep’
test_program.c:25: error: ‘mrb_state’ has no member named ‘irep’

here is the content of my test_program.c

irep member is removed and now irep is like tree structure.
And you can load irep data with mrb_load_irep(mrb, test_symbol) now.

@take-cheeze can you point me towards a working example of code being compiled from a ruby script to c using mruby? This is my first time dealing with C directly and I am having issue getting this to work

Replace

int n = mrb_read_irep(mrb, test_symbol);
mrb_run(mrb, mrb_proc_new(mrb, mrb->irep[n], mrb_top_self(mrb));

with

mrb_load_irep(mrb, test_symbol);

@Sjeanpierre I've actually thought about putting something simple together as an example so I did that real quick. Here is the repo with instructions https://github.com/carsonmcdonald/mruby-c-example
