These are just “warnings”, not “errors”.

However with ruby 2.0 you’ll see errors due to NIL_P
not put in parentheses like:

In file included from /usr/include/ruby.h:33:0,
from /usr/lib64/ruby/vendor_ruby/rbgobject.h:27,
from rbgtk.h:28,
from global.h:28,
from rbgdkevent.c:25:
rbgdkevent.c: In function ‘gdkevent_s_setting_get’:
rbgdkevent.c:390:8: error: expected ‘(’ before ‘!’ token
if NIL_P(type)
^
rbgdkevent.c:391:9: error: expected ‘;’ before ‘gtype’
gtype = G_TYPE_STRING;
^

and this patch is needed:

thanks Mamoru,

you’re right, those are just ‘warnings,’ but something is stopping the
thing from installing… (i do get a big fat ‘ERROR’ at the top.)

i’ll try the patch you mentioned, and let you know how it works out.

thanks again,

I have a similar problem when try to install rabbit gem on ubuntu 12.04
from rbgtkcalendar.c:25:
returning non-void [-Wreturn-type]
make: *** [rbgtkcalendar.o] Error 1

there is also attached the result log

Anyone can help ?

Same error.
https://github.com/ruby-gnome2/ruby-gnome2/commit/03be2d663730119036c9d70d4fc7b52523ae40df
should fix this.

Thanks for the tips.
Some minutes ago I attempt to install 1.2.2 version and the installation
work fine. Gtk2 and other related packages was installed without errors.

Bye
