Hi,

I'm  trying to use a ruby script in c++ which uses the method get of a
Net::HTTP object,
when I run it(script) in prompt it works, but when I run it in C++ it
returns an error in the get line.

ruby :

require "net/http"

#
# some code...
#

page = "www.somepage.com"
port = 80
param = "someparam"

conn = Net::HTTP.new(page,port)
resp,data = conn.get(param)                                    # get line :P

#
# some code...
#

c++ :

ruby_init();
ruby_script("script");

char *args[] =
{
     "param",
      NULL
};

ruby_set_argv((sizeof(args) / sizeof(args[0])) - 1, args);

ruby_init_loadpath();
rb_load_file("script.rb");
int status = ruby_exec();

ruby_cleanup(status);
ruby_finalize();

Error :

../lib/ruby/1.8/net/http.rb:560:in `initialize': getaddrinfo: non-recoverab
le failure in name resolution. (SocketError) from
d:/ruby/lib/ruby/1.8/net/http.rb:560:in `connect' from

d:/ruby/lib/ruby/1.8/net/http.rb:769:in `get' from script.rb:53

What's missing ? or What's wrong ? Why does the script work in prompt and
not work in C++ ?
