[GnomeMeeting-list] Building pwlib/openh323 : need to keep source directories for using the libs? (PWLIBDIR/OPENH323DIR issue)

[Vincent Rubiolo <vincent rubiolo free fr>]

Hello to all gnomemeeting stewards and stewardesses,

I am currently trying to build gnomemeeting (via GARNOME-2.10.0.1) and 
first have to build the pwlib and openh323 libraries.
The problem is that I don't want to have them in the standard ~/pwlib 
and ~/openh323 directories. As told in the docs, I appropriately set the 
PWLIBDIR and OPENH323DIR variables but this always fails when 
configuring either package.
I suspect the problem comes from the fact that you must keep your source 
_and_ installation directories for the libraries to work; this is not 
however clear at all in the FAQ : the gnomemeeting one says to --prefix 
in /usr, which I can't and the pwlib/openh323 docs are very scarce on 
the matter.
Here is a sum-up on what I tried (I'd like to install in 
~/InstalledProgs/pwlib-1.8.4 and ~/InstalledProgs/openh323-1.15.3). I 
also correctly export LD_LIBRARY_PATH to these appropriate dirs/lib as well.
+ export PWLIBDIR and OPENH323DIR to these dirs, --prefix in those 
directories as well, 'make', 'make install' : OK for pwlib but openh323 
configure then complains it cannot find version.h for pwlib
+ export PWLIBDIR and OPENH323DIR to the dirs where I unpacked the 
tarballs, no prefix at all, 'make' (no 'install' as this would go into 
/usr) : fine for both packages but then gnomemeeting complains it cannot 
find libpt (which is normal according to what the 'install' target makes).
This is where I am. I suspect the correct settings are to export 
PWLIBDIR and OPENH323DIR to the tarballs directories, then to --prefix 
to ~/InstalledProgs/pwlib-1.8.4 and ~/InstalledProgs/openh323-1.15.3 for 
each of the packages and 'make' + 'make install'.
However, this would mean to always have to keep a copy of the unpacked 
sources for the version.h file when building. This is not really 
convenient. Most GNU packages rely only on the --prefix setting and all 
is fine after that (provided you correctly export LD_LIBRARY_PATH after 
that if you are building libs).
Thanks for your help here, I am really willing to understand and commit 
a patch to the doc as well because this has bogged me down for so long 
now (and prevented me from building gnomemeeting all the way down from 
GNOME 2.6).
Note : I searched on the mailing list archives (where the posts are 
quite old) and found a post which seems to relate to the same problem as 
mine. Unfortunately, it has no answer : 
http://mail.gnome.org/archives/gnomemeeting-list/2003-August/msg00096.html
Note2 : there also seems to be a mention by Damien that these PWLIBDIR 
and OPENH323DIR variables are not needed anymore with configure ... I'm 
lost now.
