Dear community,  
I would appreciate if you could help me to solve this. I’m experimenting  
with Ruby 1.8.7 embedding. Ruby has been built from sources under  
Windows by VisualStudio 2008 compiler, with no errors.

Here is my C++ code:

void main()  
{  
\_\_try  
{  
RUBY\_INIT\_STACK;  
ruby\_init();  
ruby\_init\_loadpath();

```
            ruby_incpush( "C:/ruby1.8.7/lib/ruby/site_ruby/1.8" );
            ruby_incpush(

```

“C:/ruby1.8.7/lib/ruby/site\_ruby/1.8/i386-msvcr90” );  
ruby\_incpush( “C:/ruby1.8.7/lib/ruby/site\_ruby” );  
ruby\_incpush( “C:/ruby1.8.7/lib/ruby/vendor\_ruby/1.8” );  
ruby\_incpush(  
“C:/ruby1.8.7/lib/ruby/vendor\_ruby/1.8/i386-msvcr90” );  
ruby\_incpush( “C:/ruby1.8.7/lib/ruby/vendor\_ruby” );  
ruby\_incpush( “C:/ruby1.8.7/lib/ruby/1.8” );  
ruby\_incpush(  
“C:/ruby1.8.7/lib/ruby/1.8/i386-mswin32\_90” );

```
ruby_script( "embedded" );
rb_load_file( "test.rb" );
ruby_run();
}

```

\_\_finally  
{  
ruby\_finalize();  
}  
}

Please note, it’s only an experiment, so please don’t pay much attention  
on irrelevant mistakes.

This is my test.rb:

print “\n=== RUBY ===\n”

print “Hello World!”\*3;

print “\n\nLoad:\n”  
print $LOAD\_PATH  
print “\n”

require ‘1’  
m = My.new  
m.hello

print “\n=== GETTING LOCALHOST… ===\n”  
require ‘socket’

host = ‘localhost’  
port = 80  
path = “/”

request = “GET #{path} HTTP/1.0\r\n\r\n”

socket = TCPSocket.open( host, port )  
socket.print( request )  
response = socket.read

headers, body = response.split( “\r\n\r\n”, 2 )

print body

And that is 1.rb, which is located near test.rb:

class My  
def hello  
print “Hello from class My”;  
end  
end

The socket code actually produces segmentation fault. More precisely  
it’s the “require” statement. So everything works well except the socket  
part. And by commenting out all the socket-relevant code, I’ve learned  
that exactly the “require” statement causes the issue.

Note, everything works great when I run the script by ruby.exe, compiled  
myself!

Please help me to proceed.  
Thank you.

I’m sorry, I forgot to include the output:
