Hi!

I'm trying to compile the ruby whirlpool library from

http://izumi.plan99.net/blog/index.php/ruby-whirlpool-library/

on windows with Cygwin.

extconf.rb looks like this:

require 'mkmf'
dir_config('whirlpool')
create_makefile('whirlpool')



It doesn't give any error messages while creating the makefile,
however when I give the "make" command in cygwin, I get

Makefile:106: *** target pattern contains no %. Stop.



Line 106 of the Makefile looks like this:

install-so: $(RUBYARCHDIR)


It works fine in Ubuntu btw.

Thanks in advance
