QT Ruby

Ubuntu

sudo aptitude install libqt4-core libqt4-dev

Download qtruby from http://rubyforge.org/projects/korundum/

version=2.1.0
wget http://rubyforge.org/frs/download.php/71843/qt4-qtruby-${version}.tar.gz

Extract qtruby,

tar -xvzf qt4-qtruby-${version}.tar.gz
cd qt4-qtruby-${version}

qtruby installer uses the location of the Ruby binary it is started with,

rvm use 1.8.7
cmake .
make

Now install,

sudo make install

ubuntu doesn't look here by default, but the qtruby install puts its libraries here

sudo ldconfig /usr/local/lib

We had to run make install with root because it writes to /usr/local/lib, but it also writes to $MY_RUBY_HOME.

we don't want root-owned files floating around in there

sudo chown -R $USER:$USER $MY_RUBY_HOME
