Installing Ruby-Gnome2 on Ubuntu with RVM

Question

I have RVM running and it is working brilliantly, but I can't seem to figure out how to install ruby-gnome2. I have followed the steps on this tutorial, which are:

rvm use 1.9.1 # I use 1.9.1 which should work with ruby-gnome2
wget http://downloads.sourceforge.net/ruby-gnome2/ruby-gnome2-all-0.19.4.tar.gz
tar zxf ruby-gnome2-all-0.19.4.tar.gz
cd ruby-gnome2-all-0.19.4/
ruby extconf.rb —ruby=`which ruby`
make
make install

This produces no errors, so I assume it worked. So I try to test it with:

$ irb
irb(main):001:0> require 'gtk2'

Which gives me this error:

irb(main):001:0> require 'gtk2'
LoadError: no such file to load -- gtk2

Why am I not able to install ruby-gnome2?

Answer 2

Install system dependecies:

sudo apt-get install libglib2.0-dev libatk1.0-dev libcairo-dev libsqlite3-dev libpango1.0-dev libgtk2.0-dev libgdk-pixbuf2.0

Install gtk2 gem which is ruby-gnome2:

gem install gtk2

You can run this tiny script to verify that gtk2 is installed:

require 'gtk2'

win = Gtk::Window.new("My ruby-gnome2 project")

win.show_all

Gtk.main

Answer 3

In order to build ruby-gnome2 for RVM with all dependencies, ensure the following packages are installed before you build your ruby binary:

sudo apt-get install libatk1.0-dev libpanel-applet-4-dev libgtksourceview2.0-dev libvte-dev libgstreamer0.10-dev libbonobo2-dev libbonoboui2-dev libgtk2.0-dev libgdk-pixbuf2.0-dev libgtksourceview2.0-dev libpango1.0-dev libpoppler-dev libglade2-dev libart-2.0-dev libgnomeprint2.2-dev libgnomecanvas2-dev libgtkglext1-dev libgnomeprintui2.2-dev libgoocanvas-dev libgnomevfs2-dev libgconf2-dev  librsvg2-dev

You can rebuild it again after installing these with:

rvm install 1.9.1

Then, follow the instructions you posted:

rvm use 1.9.1 # I use 1.9.1 which should work with ruby-gnome2
wget http://downloads.sourceforge.net/ruby-gnome2/ruby-gnome2-all-0.19.4.tar.gz
tar zxf ruby-gnome2-all-0.19.4.tar.gz
cd ruby-gnome2-all-0.19.4/
ruby extconf.rb —ruby=`which ruby`
#   Alternatively you may use the following line
#   to install into rvm's dir and avoid conflict with system libs
# ruby extconf.rb --ruby=`which ruby` --prefix=$MY_RUBY_HOME
make
make install

Answer 4

I hope that, when you followed those instructions, on the line:

ruby extconf.rb —ruby=`which ruby`

You actually:

• used two dashes -- (the code in the page replaced those two dashes with a long one)
• replaced the `which ruby` (note the backticks) with the actual output of running that command on your OS (with no backticks)

If not, that's your error.

If you actually did all those, please post the output you got from the ruby extconf.rb ... line.
