:-) left guile-devel only this time

Yes. Just made things working both with guile-1.6 and guile-1.8 [on the same
machine I mean], by changing the module definition as this [if others would
like to
do so...]:
;; --
(define-module (struct gtrees))
(let ((ef-ver (string->symbol (effective-version))))
(case ef-ver
((#{1.6}#)
(dynamic-call "init_gtrees_module"
(dynamic-link "/usr/local/lib/gtrees-0.3/libgtrees.so")))
(else
(dynamic-call "init_gtrees_module"
(dynamic-link "/usr/local/lib/gtrees-0.5/libgtrees.so")))
))

Well, as much as possible, due to the amount of work I have, I'll stick to
debian
packages until I finish the application I am working on, then I'll try 2.0 and
guile-vm, I can't wait! but I have to :-(

If you remember, thanks to dsmith, on xchat, I could produce a guile-pg [debian]
package patched that works with guile-1.8 [the problem was a dependency one:
here is
what I wrote to myself:
;;;
;;; Debian package [patching guile-pg-0.16]
;;;
A] Getting the source
cd ~/alto/admin/guile-pg
apt-get build-dep guile-pg
apt-get source guile-pg
cd guile-pg-0.16
B] Changing the dependency towards guile-1.8
cd guile-pg-0.16/debian
perform the following change
< Build-Depends: debhelper (>> 4.0), quilt, libpq-dev, guile-1.6-dev
> Build-Depends: debhelper (>> 4.0), quilt, libpq-dev, guile-1.8-dev
But I also wrote something about patching libpostgres.c and .h,
[postgres-7.4: the only SW that's still is not a debian package [in my
dependency 'little tower'] but a manual compilation [and they are @ 8.4
now,
so quite late on this side too ...] can't find right now but if people
are
interested i'll make that info avalable too, let me know.
C] Then I changed the module definition [attached]
;; --
So I was wondering, in order to be as practicle as possible and save 'lost'
debugging time, is it possible to install both guile-gnom0 and guile-gnome2 on
the
same machine ?
I think I tried and didn't work, but I might be wrong.
That would fantastic because I could right away porting the development I am
doing
and later on port the old apps.
Cheers,
David
