Hello,

I created a very small C library for Ruby.  It compilies and works great on Windows 2000 using cygwin.  On Windows XP, however, I get the following run-time error:

Exception `LoadError' at /usr/local/lib/ruby/site_ruby/1.6/locana_gui_mswin32.rb:4 - dlopen: Win32 error 5 - /usr/local/lib/ruby/site_ruby/1.6/locana_gui_mswin32_ext.so /usr/local/lib/ruby/site_ruby/1.6/locana_gui_mswin32.rb:4:in `require': dlopen: Win32 error 5 - /usr/local/lib/ruby/site_ruby/1.6/locana_gui_mswin32_ext.so (LoadError)
        from /usr/local/lib/ruby/site_ruby/1.6/locana_gui_mswin32.rb:4
        from /usr/local/lib/ruby/site_ruby/1.6/locana/locana_bindings.rb:101:in `require'
        from /usr/local/lib/ruby/site_ruby/1.6/locana/locana_bindings.rb:101
        from /usr/local/lib/ruby/site_ruby/1.6/locana.rb:279:in `require'
        from /usr/local/lib/ruby/site_ruby/1.6/locana.rb:279
        from tst/tst_locana.rb:15:in `require'
        from tst/tst_locana.rb:15

Has anyone seen this error before and/or have any suggestions on how to work around it?  I an running the latest cygwin on XP.  The gcc compiler is gcc version 3.2 20020927 (prerelease).  

Any suggestions on how to work around this issue is greatly appreciated.

Thanks, 

Michael Davis

PS, here is the content of a few important files incase it helps:

contents of locana_gui_mswin32_ext.def:

	EXPORTS
	Init_locana_gui_mswin32_ext

contents of extconf.rb:

	require 'mkmf'
	case RUBY_PLATFORM
	when /cygwin/,/mingw/
	  $CFLAGS = "-fno-defer-pop -fno-omit-frame-pointer"
	  create_makefile("locana_gui_mswin32_ext")
	when /win32/
	  create_makefile("locana_gui_mswin32_ext")
	end

first few lines of locana_gui_mswin32_ext.c:
