Problem with installing Ruby GTK

[Karthikeyan A k]

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:
