If you mean the commands: cd qt ./qtguess.pl ./generate.pl make they're not enough. As the README states, they're only to generate the .cpp files. What you need is the following: * go in the top level directory of qtruby * mkdir build * cd build * cmake .. * make * sudo make install This will install qtruby4 in /usr/local (excluding the ruby bindings themselves, which will be installed in /usr/lib/ruby/site_ruby/1.8 (or something like this, depending on whether ruby itself is installed). If you want to install it somewhere else, replace the cmake .. command with cmake -DCMAKE_INSTALL_PREFIX=/path/to/install/dir .. I think this should solve your problem. If you have other questions about qtruby, you can post them in the qtruby forum, which you can find at http://rubyforge.org/projects/korundum, where you'll be more likely to get an answer (and a better one, too, since there questions are answered by the developers themselves). I hope this helps Stefano
