Subject: [ruby-talk:24137] Embedding ruby and net libraries

Hi,

I've managed to get Ruby embedded into a c++ program and would like to use
some of the Net modules from within the app. 

I'm using rb_eval_string_protect to a string like so: 

		int state = 0;
		
		char* mailme = "require 'net/smtp' \r\n \
					msg = [ \"Subject: Test\n\", \"\n\",
\"Test message\n\" ] \r\n \
					Net::SMTP.start('xxx.xxx.xxxx') do
|smtp| \r\n\
						smtp.sendmail( msg,
'martin@massive.com.au', ['martin@massive.com.au'] ) \r\n\
					end";


		result = rb_eval_string_protect(mailme, &state);
		if (state) {
			result = rb_inspect(rb_gv_get("$!"));
	 		char* e = RSTRING(result)->ptr;

		}

When run I get the following error message in e:
#<LoadError: (eval):7:in 'require': No such file to load -- net/smtp>

If I move the net dir from the ruby distribution into the directory I'm
running from and change the require to require 'net/smtp.rb' then smtp.rb is
found. However smtp.rb requires 'protocol' so I end up with the same
exception, except this time:
#<LoadError: net/smtp.rb:in 'require': No such file to load -- net/protocol>

Is there a way of overcoming this annoyance so that the networking libs can
be used by and embedded interpreter?

regards,

Martin
