[Ecls-list] compatible gui libraries

[Alessandro Serra]

Hi,
I successfully compile cl-gtk2 using ecl. A few problems arise:
* compiling cl-gtk2 takes a lot of time (half day). It spends a lot of
time to compile the foreign funcall such as:
       /*	Compiler: ECL 11.1.1                                          */
       /*	Date: 2011/2/22 17:58 (yyyy/mm/dd)                            */
       /*	Machine: Linux 2.6.32-28-generic i686                         */
      /*	Source: (LAMBDA (OBJECT NEW-VALUE) (FOREIGN-FUNCALL
       gtk_container_set_focus_child
       G-OBJECT OBJECT G-OBJECT NEW-VALUE VOID)) */
and the classes with  gobject-class as metaclass.
* runtime, it is really slow. It takes several seconds to response to a click.

The same code, perfectly compile and run  with sbcl.
Do you have any idea where could be the problem? weak pointer? metaclasses?

Thanks,
Alessandro
