irb(main):001:0> require ‘pro1’
=> true
irb(main):002:0> include Pro

irb(main):003:0> Pro::load
=> false
irb(main):004:0>
i get only false…
dll fails to load through ruby…
how can i get the stacktrace ?
Any Advices…
Pls help me out
Thanks
below is my pro1.c code
#include “windows.h”
#include “ruby.h”
#include “pro.h”
