Re: [Ltib] dbus cross compilation

[Stuart Hughes]

Hi Tarek,

I've committed the attached SPEC file to Savannah CVS (and also updated 
packages.lkc).  In this case I pre-set the configure option to avoid the 
 cross-compilation intermediate executable test you ran into.

So far as dbus-glib goes, hopefully you'll be able to figure that out by 
looking at dbus.  If you do, please submit a patch back.

Regards, Stuart
