i was having some problems running green shoes on my 64bit linux box,
and eventually those problems were solved. here is how. (note: this
is to solve the problems *right now* they will be solved in the next
release of ruby-gtk2)
anyway, the meat & potatoes of the error was this:
`/home/serialhex/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
`require': uninitialized constant Gdk::Drawable (NameError)`
go find your gtk2 gem, it's probably in gems/gtk2-1.0.0/ or something
(in my example it tells you very simply). for me it's at:
`/home/serialhex/.rvm/gems/ruby-1.9.2-p290/gems/gtk2-1.0.0/`
go into the `ext/gtk2` dir in there and open the file `rbgtkinits.c`
in that file, make 2 changes:
take line 240:
void Init_gtk_inits(void)
{
Init_gtk_gdk_gc(); <----- line 240
...
}
and move it to the end:
void Init_gtk_inits(void)
{
....
Init_gtk_gdk_gc(); <------ last
}
then, in that dir (on mine it's
`/home/serialhex/.rvm/gems/ruby-1.9.2-p290/gems/gtk2-1.0.0/ext/gtk2` )
run `make`, drink some water (or coffee, or red bull)
when that is done, copy `gtk2.so` to the `lib` dir:
$ cp gtk2.so ../../lib
then go, and have fun with your gtk or green shoes app
