Thanks Mats! That helped.

I didn't realize that only lsb-buildenv-3.1.1-1.i486.rpm from the following 
URLs should be installed on the host system and the rest 
(lsb-build-desktop-3.1.1-1.i486.rpm and lsb-build-cc-3.1.1-1.i486.rpm) 
should be installed after chroot-ing into the Build Environment. I 
concluded, before, wrongly that lsb-buildenv was the big bundle of all 
other rpms.
http://ftp.freestandards.org/pub/lsb/lsbdev/released-3.1.0/binary/ia32/

Probably adding a README file in the directory explaining that not all rpms 
should be installed to the host system would help.

So, in chroot BE environment, I installed these 2 packages:
rpm -ivh --nodeps lsb-build-cc-3.1.1-1.i486.rpm 
lsb-build-desktop-3.1.1-1.i486.rpm

Thanks for the information.


So, with the pkgconfig's .pc files in place, things (pkgconfig) looks 
better now.

The same gtkhello.c is now giving me preprocessor errors:

In file included from /opt/lsb/include/gtk-2.0/gtk/gtk.h:5,
                  from gtkhello.c:3:

Those were caused missing GLib headers:
$ ls /opt/lsb-buildenv-ia32/opt/lsb/include/glib-2.0/glib
gprintf.h  gstdio.h

Note that galloca.h, etc. aren't in the above directory. Those header files 
are included as follow:

/opt/lsb-buildenv-ia32/usr/include/glib-2.0/glib.h:
#ifndef __G_LIB_H__
#define __G_LIB_H__

#include <glib/galloca.h>
#include <glib/garray.h>
#include <glib/gasyncqueue.h>
#include <glib/gatomic.h>
...


Any idea why these GLib headers are missing from the BE rpms?
