Hi y’all:
I’m trying to install my visualruby gem on a windows machine, and I
don’t understand the requirements.
First, I installed ruby’s one click installer ver1.9.2 from here:
Also, I installed glade+GTK+ from this site:
http://ftp.gnome.org/pub/GNOME/binaries/win32/glade3/3.6/
Then I type:
gem install visualruby
It complains that I need the development package because there is a
problem with “cairo.”
So I went back to the rubyinstaller page, and installed the developent
package using their instructions. It seemed to install successfully.
But now when I try to install the visualruby gem, I get the message:
looking for cairo etc…
extconf.rb failed
I’m trying to update my install instructions, so my program is usable.
It sucks when you can’t even install your own program. Help.
Andrea???
I hope I can have simple install instructions like:
- Install glade+GTK+
- Install ruby 1 click installer
- Install visualruby gem
What am I missing? What is the problem?
Thanks,
Eric

Could you try again the command?
I updated a Windows binary bundled cairo gem. It will solve
your problem.
Thanks,

Thanks for getting back to me kou.
I’m still getting the cairo problem, and its in Windows and Ubuntu.
Here’s the message from ubuntu:

It must be a problem with the gem because I’m installing glade 3.6.7
which iss an old program, and has worked before. The windows gtk is
also mature.
I’m getting the same error when I just try to install the cairo gem:
gem install cairo

Could you install the following gem on Windows?

(Maybe) I fixed the problem.
Could you try the following commands on Ubuntu?
% wget http://pub.cozmixng.org/~kou/archives/cairo-1.12.1.gem
% gem install cairo-1.12.1.gem
Thanks,
kou
Thanks kou!!! You’re a genius!! That fixed the install for cairo on
Ubuntu and Windows.
However, now I’m getting an error when it tries to install psych.
Its saying psych failed to install, checking for yaml.h …no!
So the yaml.h is missing due to not having libyaml (???) installed?
I could probibly try to fix this but I’m going to need to understand
what’s going on to write my install instructions. Does anyone know what
this means? I know that when I use rubygems api to install gems, it
breaks due to a bug in yaml. Installing psych fixes the bug.
