anyone here using gentoo?
i just installed from the ruby overlay dev-lang/ruby-1.9.0.4-r1 and
[ebuild R ] dev-ruby/ruby-glib2-0.18.1 0 kB [1]
[ebuild R ] dev-ruby/ruby-gdkpixbuf2-0.18.1 0 kB [1]
[ebuild R ] dev-ruby/ruby-pango-0.18.1 0 kB [1]
[ebuild R ] dev-ruby/ruby-atk-0.18.1 0 kB [1]
[ebuild R ] dev-ruby/ruby-gtk2-0.18.1 0 kB [1]
[ebuild R ] dev-ruby/ruby-gtksourceview-0.18.1 0 kB [2]
looks like it installed files in the right places, but:
$ irb19
irb(main):001:0> require ‘gtk2’
LoadError: /usr/lib/ruby/site_ruby/1.9.0/i686-linux/gtk2.so: undefined

Use latest stable Ruby (version 1.8.7-p72) instead of unstable 1.9?

Yes, as we talked about in a different discussion, ruby-gtk does not
work with ruby 1.9 
Hmmm… SInce we’ve hit this problem more than once in the past few
weeks, maybe it would be worth putting a warning on the Ruby-GNOME2
web page. Maybe in the text of the “What’s Ruby-GNOME2?”
section. Here’s my suggestion:
"Ruby-GNOME2 is a set of Ruby 1.8.7 language bindings for the GNOME 2.0
development environment. This is the next generation of Ruby-GNOME.
Note: Ruby-GNOME2 does not currently work with Ruby version 1.9.
The only version of Ruby that is currently supported is version 1.8.7."
That way when people try to compile it by hand and run into trouble,
they will hopefully realize the problem quickly.

i switched to ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux], but
that gives me a lot of ‘[BUG] object allocation during garbage
collection phase’, which i can’t identify.
can anyone help me with that?
thanks in advice

double check you’re still using rg2 0.18.1, then reduce as much as
possible the length of a sample script triggering that bug and try to
make it happen everytime you run the sample script and explain how to
trigger it, and send that script over
notice to kou: I also still experience that bug with 0.18.1 and ruby
1.8.7, but it happens rarely and I was unable to create a small test
case; I’ve seen in commit logs that some post 0.18.1 commits may
already fix that though (commits related to GC for example)

i just ran into a “[BUG] object allocation during garbage collection
phase” with ruby 1.8.6 (2008-08-08 patchlevel 286) [i686-linux], in the
following line:
cr.curve_to(x1+m1,y1,
xr+(x1-xr).absMath.cos(f3),yr-(yr-y1).absMath.sin(f3),xr,yr)
where cr is a cairo_context
and i can’t reproduce it

i have this error on almost every ruby version i tested (rubyee, ruby
1.8.7) except on ruby 1.8.6 (2008-03-03 patchlevel 114) [i686-linux]
and i think the problem is related to threading.

i had this in my script:
Gtk.timeout_add(20000){
ocs=ObjectSpace.each_object{}
garbage_collect
GC.start
oce=ObjectSpace.each_object{}
p "started:#{ocs} finished:#{oce} freed:#{ocs-oce} objects"
true
}
if i removed that, i don’t get the ‘object allocation during garbage
collection phase’

can you send the smallest possible self-contained script for
reproducing that problem?

i don’t promise that
my situation is a bit complex:
i run a threaded rub server which holds structured data(ex. hashes,
arrays) clients read those data into specific widgets(created/destroyed
runtime ex. TreeViews,RCairo widgets created by me) via druby on
background threads.
so i can find my problems, if ruby exits with information with my files
and linenumbers where the error occured, but when there is just a ‘BUG,
segfault’ than i’m just guessing.
but if i’ll not be able to work around my threading problems, i might
try to reproduce this in a simple script.
