Install error - gtk2 on ubuntu natty (11.04)

Desktop Ruby-Gnome 2

Hi everyone,

I’ve tried to install gtk2 on ubuntu natty 11.04 but i receive an
error
during the installation:

(after sudo gem1.9.1 install gtk2)

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
*** extconf.rb failed ***

gobject-2.0 seems to be missing though i’ve installed libgtk2.0-dev
(which is
supposed to install all the dependencies needed for building the native
extensions). Has anybody tried to install the gtk2 gem on ubuntu 11.04?

hi andrea -

well, i wish i had some answers for you - i’ve had problems installing
the latest gtk2 on ubuntu 10.04 as well (there are several posts on this
board about my troubles…)

for the moment i use the version that came with my package installer
(0.19.3) and that works fine, though i’m missing some features from the
newer version… does your package installer have a “libgtk2-ruby”
package?

Not yet.
Does /usr/lib/pkgconfig/gobject-2.0.pc is present on your computer ?

Looks like there is no way to use ruby gtk2 on ubuntu 11.04. I have
tried all methods and have exhausted.

That’s good to know since I was just about to upgrade. Any ideas on
what the problem is?

I just tested to run “ruby extconf.rb” in glib2 directory on ubuntu
11.04.
I have the same error. I Install libglib2.0-dev package to resolve it.
I can now build ruby-glib2 without errors.

libglib2.0-dev installs /usr/lib/pkgconfig/gobject-2.0.pc file that
why I ask to check for it in a previous mail.

turns out that on Natty some .pc files (including gobject-2.0.pc) are
placed in /usr/lib/i386-linux-gnu/pkgconfig instead of
/usr/lib/pkgconfig; thus I solved the problem by following these steps:

I’ve added /usr/lib/i386-linux-gnu/pkgconfig to the default
.pc search path in pkg-config.gem and released
it. (pkg-config gem 1.1.1 is the latest version.)

Please try again.

Works like a charm now.
