Problem with installing Ruby GTK

Ruby
1

Hello People,

I tried to install Ruby GTK using the following command on my Ubuntu:

$ sudo gem install gtk2

and it spits out some error as shown:

Building native extensions. This could take a while…
ERROR: Error installing gtk2:
ERROR: Failed to build gem native extension.

/usr/local/ruby/bin/ruby extconf.rb
checking for GCC… yes
checking for rb_define_alloc_func() in ruby.h… yes
checking for rb_block_proc() in ruby.h… yes
checking for new allocation framework… yes
checking for attribute assignment… no
checking for Win32 OS… no
checking for gobject-2.0… no

How to fix it?

Hi, you might need some extra libraries to build this gem, gobject-2.0
for example.extconf.rb have not found gobject-2.0.
install all dependencies and try again

Hi.
It’s probably missing the Ubuntu GTK2 developer packages.

Try the following command:

% sudo aptitude install -y libgtk2.0-dev
% sudo gem install gtk2

Thanks,
