Subject: Re: questions about embedding ruby 1.9

Do you nee to add rb_init_loadpath()?

    ruby_sysinit(&argc, &argv);
    {
        RUBY_INIT_STACK;
        ruby_init();
        ruby_init_loadpath();


My own embedded ruby interpreter require's a file, and then calls 
functions within it.  The rb_require and rb_funcall are wrapped in 
rb_protect.

The protected rb_require allows me to log any syntax errors in the 
required code.  The protected rb_funcall allows me to catch any 
exceptions.

Ruby's own main.c uses something different to load the script:

    ruby_sysinit(&argc, &argv);
    {
        RUBY_INIT_STACK;
        ruby_init();
        return ruby_run_node(ruby_options(argc, argv));
    }

Cheers,
Gra.
