Forum: Ruby-Gnome 2 Install error - gtk2 on ubuntu natty (11.04)

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?

Andrea

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.

Installing libglib2.0-dev didn't work on my 11.04 Ubuntu machine. It
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:

$ sudo apt-get install {libpango1.0,libglib2.0,libatk1.0,libcairo2,\
libgdk-pixbuf2.0,libgtk2.0}-dev

$ cd /usr/lib/pkgconfig/

$ sudo ln -s ../i386-linux-gnu/pkgconfig/{atk,fontconfig,\
freetype2,gio-2.0,gio-unix-2.0,glib-2.0,gmodule-no-export-2.0,\
gobject-2.0,gthread-2.0,libpng,pangocairo,pangoft2,pango,\
x11,xau,xcb,xcb-render,xcb-shm,xcomposite,xcursor,xdamage,xdmcp,\
xext,xfixes,xinerama,xi,xrandr,xrender}.pc .

$ sudo gem install gtk2


Hope it helps.

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.
