GNOME 2 compilation issues

[ERDI Gergo <cactus cactus rulez org>]

Hi,

I decided to give a try to installing the base GNOME2 libraries. My battle
plan was to install packages from HEAD in the following order:
glib, pango, gtk+, linc, ORBit2, gnome-common, gnome-xml, oaf, gconf,
gnome-vfs, libgnome-2, libgnomecanvas-2, libgnomeui-2. I am posting my
experiences to point out problems and to help others who want to set up 
their GNOME2 environment so they can hack on it.

GLIB and Pango compiled and installed just fine. The gtk+-2.0.m4 from gtk+
HEAD re-defines the Autoconf macro for looking for GLIB, and uses the
depracated glib-config-2.0 method instead of using pkg-config. This has to
be removed from gtk+-2.0.m4.

The real problems, however, began with ORBit2. First of all, there is big
confusion how to check for ORBit2 in other packages: some of them use
pkg-config (which I guess is the way to go), but ORBit2 has no .pc.in
file; and some other packages use orbit-config directly, but this makes
having ORBit and ORBit2 installed at the same time more difficult. I
hacked up an ORBit-2.0.pc.in file for libgnome-2, but it is definitely not
straightforward because of the --use-service thing in orbit-config (maybe
there should be multiple .pc files installed by ORBit2?).
Also, due to ORBit2 expecting the GLIB checking macro to use the old,
glib-config-2.0 way, @GLIB_2_0_CONFIG@ is not substituted in orbit-config
(this doesn't really need to be fixed since pkg-config should be used
instead of orbit-config eventually).

Thinking that I have finally solved ORBit2 problems, I went on with
gnome-xml. For some reason, include/libxml/entities.h was not installed,
but I was unable to reproduce it (running autogen.sh and make install
again fixed it) so I have no idea if the problem was genuine or a fault in
my setup.

However, then came the point where I would install OAF 0.7.0. The
configure script uses orbit-config instead of pkg-config and writes the
ORBit linking flags to oaf-2.0.pc (i.e. it's ugly). When I tried to
compile oafd, it was missing the definition of
TC_CORBA_sequence_CORBA_string_struct from libORBit.so. Indeed, it is for
some reason not part of it:
[gnome2] 17:17:07 [cactus galaxy lib]$ nm libORBit.so |grep

0002e760 D TC_CORBA_sequence_CORBA_unsigned_long_long_struct
0002e660 D TC_CORBA_sequence_CORBA_unsigned_long_struct
0002e560 D TC_CORBA_sequence_CORBA_unsigned_short_struct
0002e3e0 D TC_CORBA_sequence_CORBA_wchar_struct

I have absolutely no idea what the problem here may be, so right now I'm
stuck at trying to compile oaf. Can anyone tell me what's up here?

Also, please tell me if I should continue posting my experiences as I
(hopefully) go forward in installing more and more of the constantly 
changing pieces of what will eventually become the GNOME2 puzzle.
