Hi there, I get the following: [root@li137-46 tenderlove-nokogiri-0e2a3d9]# rake-compiler /usr/lib/ruby/gems/1.8/gems/rake-compiler-0.7.0/lib/rake/ extensioncompiler.rb:28:in `mingw_host': No MinGW tools or unknown setup platform? (RuntimeError) from /usr/lib/ruby/gems/1.8/gems/rake-compiler-0.7.0/bin/../tasks/bin/ cross-ruby.rake:40 from /usr/lib/ruby/gems/1.8/gems/rake-compiler-0.7.0/bin/rake- compiler:21:in`load’ from /usr/lib/ruby/gems/1.8/gems/rake-compiler-0.7.0/bin/rake- compiler:21 from /usr/bin/rake-compiler:19:in `load’ from /usr/bin/rake-compiler:19 It doesn’t seem to matter if I install it via yum or gem, the same error occurs. Help! Thank you in advance, Gloria ---

I don’t use MingW on Fedora. I don’t want to cross compile for Windows at all. I want to build natively, of course. ---

You also don’t need to invoke “rake cross compile” when compiling natively. ---

Thank you. I’m following nokigiri build instructions, and this was not clear. Gloria ---
