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
