Ruby bindings for GNOME

This is a set of bindings for the GNOME 3.x and 4.x libraries to use from Ruby that allows you to write graphical user interfaces in Ruby.

Ruby can be run from the system directories, or from your home directory, or both.
Most people won't have the correct permissions for a system install, so the vast majority of people to run Ruby from their local, /home/... directory.

To test if your copy of Ruby is running locally enter this on the command line:

which ruby

If it outputs something like this:

/home/ralph/.rbenv/shims/ruby

that starts with /home/, that's local (good!)

But if outputs something like this:

/usr/bin/ruby

That is a system directory, and the gtk4 gem will fail to install. Actually, a system administrator with super-user permissions could install everything in the system folders (see advanced install), but its much better for everyone else to run Ruby locally.

If you're already running a copy of Ruby under your home directory, you can install gtk4 (or gtk3):

gem install gtk4

But if you're running ruby from the system folders, you can install a Ruby version manager like RVM or rbenv.
These programs allow you to run multiple versions of Ruby from your home directory.

rbenv has a rbenv-installer that installs everything and adds a line to your .bashrc file so you're running local copies of Ruby.

To get rvenv:

1. Run the installer
2. Restart your command prompt
3. Run rbenv install --list (find recent Ruby version)
4. Run rbenv install 3.3.5 (example version. choose one from list)
5. Run which ruby (check that its running from home directory)

If that works, then you're ready to install gtk4 (or gtk3):

gem install gtk4

Input needed...

In Windows, the gem should be installed without issue. If you install Ruby using the Ruby Installer, make sure that MSYS2 gets installed too. GTK needs MSYS2 to make the binary files. Then, at the Ruby command prompt:

gem install gtk4

sudo apt install -y gcc make ruby-dev
sudo gem install gtk4

You can also install these gems from GitHub master branch.

Create Gemfile like the following:

source "https://rubygems.org/"

git "https://github.com/ruby-gnome/ruby-gnome.git" do
  gem "gtk4"
end

Install these gems by Bundler:

% bundle install

% ruby extconf.rb
% make
% sudo make install

To compile and install a particular sub-binding, you can add arguments:

% ruby extconf.rb [subdir]...
e.g.) ruby extconf.rb glib2 pango atk gdk_pixbuf2 gtk4

Or you can compile each sub-binding:

% cd <each sub-directory>
% ruby extconf.rb
% make
% sudo make install

• --ruby

  • ruby directory

• --topsrcdir

  • top source directory

• --topdir

  • top directory

• --strict

  • if some libraries fail to compile/install, "make" command returns 1(exit 1)
