Hi all -

Since about Ruby-GNOME2 0.19.0 or so, the create\_cairo\_context method no  
longer exists and aborts my program (which relies on it, there is no  
point  
to my program without it).

According to gdk documentation here:  
[http://library.gnome.org/devel/gdk/stable/gdk-Cairo-Interaction.html](http://library.gnome.org/devel/gdk/stable/gdk-Cairo-Interaction.html)

There exists a new method called gdk\_cairo\_create which I think takes  
the  
place of the old Gdk::Window.create. Is this wrapped in Ruby-GNOME2,  
and  
how can I call it? I’d like to get my program working again.

Thanks!  
dave

You need to install rcairo before you build Ruby-GNOME2.

## Thanks,

Thanks. I was using my distribution’s build (Archlinux) and that did  
not  
seem to have Gdk::Window.create\_cairo\_context available. I checked out  
SVN  
ruby-gnome2 (rcairo was already installed from Arch repositories), built  
it,  
and it all worked again.

I’ll file a bug with Arch about it.

thanks,  
dave

i’ve seen this on gentoo.  
ruby-gtk2 built with rcairo-1.8.1 has the mentioned cairo\_conext method  
missing ( also in PrintOperation)  
ruby-gtk2 built with rcairo-1.8.0-r1 works as expected.

which rcairo version did you use on archlinux?

thanks,  
Balint

Hmm. Running into this problem again.

Is there a recommended version to work?

As in, which cairo version to use and which rcairo version to use?
