guile-gobject 0.3.0 Released

guile-gobject 0.3.0 Released

[Ariel Rios]

Hello Happy GNOME schemers!

This is the second public release of guile-gobject the new guile
bindings base for GNOME 2.0. Please be aware that this code is
totally untested and might not even work at all =)

This package includes:

(gnome gobject):the guile implementation for GNOME 2's type system,
libgruntime (glib/gobject in GNOME CVS). It enables not only to wrap
the C glib/gobject API but it aslo gives you full acces to the
new GNOME 2 type system.
 
(gnome corba): CORBA support for guile.  Depends heavily on ORBit2

The rest of the package contains unfinished and untested gtk bindings.

Availability:
http://linux.cem.itesm.mx/~ariel/download/guile-gobject-0.3.0.tar.gz
or through GNOME CVS via the guile-gobject module

Requirements:
-GNOME 2 Platform
-guile 1.5.4

I would like to thank Martin Baulig the original author of this set,
Michael Meeks and James Henstridge who helped me sort out some Gtk+ and
Corba problems.

Enjoy,
ariel

The GTK2 bindings will also be available independently, right?  Once
it's released anyway.  Not everyone uses GNOME.

Thanks for the great work!

I can continue to disitribute both guile-gtk and gnome-guile.
This will make happy schemers to many of our users ;)

I'm afraid I'm confused about the future of guile-gtk.

Could Ariel (or perhaps someone else who is also working on it) please
clarify what the intentions for continuing development are?

Reasons for asking:

  * I could not get the guile-gtk 0.21pre4 release to build against GTK
    2 (1.3), and configuration code that appeared to be for GTK 2 was
    disabled.  I had the same problem with CVS version.

  * When built against GTK 1.2 and Guile 1.5.4 CVS, some of the
    guile-gtk widget demos have errors (possibly due to Guile changes).
    It was also unclear how much new functionality has been added in
    recent times.

  * Ariel's true love may be the full Gnome platform in all its glory,
    and it may be asking too much of him -- or anyone -- to burden him
    with separately developing and maintaining *non*-Gnome GTK bindings.

No flame intended; I just need to understand where guilt-gtk is going if
I'm to be able to use Guile at all.  So far it's been confusing.

Please note that guile-gobject won't work for me and some other people,
since anything Gnome-dependent presents technical (e.g., size,
complexity) and/or political issues.  However, Guile bindings for GTK 2
(and perhaps Pango and Libart), are very much desired -- so long as they
are independent of Gnome.

Thanks,
Neil V.

the guile-gtk 0.2x series will only support Gtk+1.2.x

Yep. I do love GNOME. I see GTK as a part of the complete GNOME
platform. However I do know that most of guile-gtk
does not want to have GNOME installed.

What I'm planning to do? In the future we will have 3 packages:
-guile-gobject: The basis for all bindings. It is a wrapper for 
glib and thus for the new gobject.

-guile-gtk2: Gtk+2 bindings for guile (maybe pango can come hear...)

-gnome-guile2: The complete GNOME platform bindings for guile.
It will contatin support for bonobo, corba, gtk+2, etc.


Following this scheme, you have to choose between guile-gtk2 or
gnome-guile2. If you chose the latter it will include the guile-gtk2
package.

I think this is the way to go =)

Any suggestions. Hope this clarifies the situation =)

Re: guile-gobject 0.3.0 Released

[Neil W. Van Dyke]

In case anyone else has trouble building guile-gobject 0.3.0, here's the
minor changes I needed.  Haven't actually run it, but it compiled.

1. File "gobject/guile-gnome-gobject-primitives.c": Renamed identifiers
   beginning with "g_param_get_" to begin with "g_param_spec_get_", per
   http://mail.gnome.org/archives/gnome-2-0-list/2001-November/msg00121.html

2. File "corba/Makefile.in": Added "$(GUILE_CFLAGS)" to "INCLUDES".

3. File "corba/guile-gnome-corba-types.c": Temporarily added explicit cast to
   get it to compile:   g_message (G_STRLOC ": %d", (int)gtype);

4. Dependency on "libxml2" devel library does not seem to be checked by
   configure script.  Other libraries might also need checking; this one 
   noticed only because this particular box happened to be missing that
   library.

Thanks for this info, it saved some time. Even after applying your 
changes i couldn't compile guile-gobject with my CVS guile . 
It seems that the code uses some deprecated/removed features. To get
a more or less error free compile i had to do the following:

 - change type 'scm_bits_t' to 'scm_t_bits' (see file NEWS in guile-core).

 - change 'LIST1, LIST2 ... LISTN' to 'scm_list_1 ... scm_list_n'
   (again, see file NEWS in guile-core).

 

With these modifications i can at least compile the shared library part.
Now, during 'make' i get the following errror:

|  make[2]: Entering directory `/home/ralf/projects/guile-gobject-0.3.0/gobject'
|  FLAVOR=gnome guile -c \
|  "(set! %load-path (cons \"..\" %load-path)) \
|   (primitive-load \"./gnome-gobject.gwp\")"
|  ERROR: Unbound variable: nil
|  make[2]: *** [gnomegobject.h] Error 2
|  make[2]: Leaving directory `/home/ralf/projects/guile-gobject-0.3.0/gobject'

|  make[1]: Leaving directory `/home/ralf/projects/guile-gobject-0.3.0'
|  make: *** [all-recursive-am] Error 2
|  
 
Hmm,  no idea where 'nil' is supposed to come from. 
A quick grep didn't reveal anything. Ariel, any hints?

Aha, fame at last!  I removed `nil' from libguile, because its only
purpose was as part of some obsolete support for Emacs Lisp.

Can you try and find out what guile-gobject is using `nil' for?  On
the one hand, the binding in libguile may have been hiding a bug in
guile-gobject; on the other hand, there may be a genuine need, in
which case we can look at putting it back.

In the meantime, a workaround should be:

(define nil 'nil)
