gnome 2.8.0 and external dependencies

I think they are mentioned there because these packages are all external 
and not hosted with all the other gnome packages, though they also do 
explicitly list e.g. libxml2.

I have tried several times to build mozilla, it shouild work AFAICS, but 
the build system is a mess, at least I was able to build spidermonkey.

No, I introduced a bug in the glib2 update, I'll upload another update 
tomorrow.  GLib uses dlopen() then.  The other three yes, they don't 
depend on GLib.  After I have GLib updated I'll need to recompile atk, 
pango and gtk+ which were ready but Martin reported the GLib bug so I 
didn't uploaded them yet.  The new updates are based on libtool-1.5.10 
now which seems to work fine here.

That is the reason why we must use libtool-1.5.10, there are data 
symbols in some Glib objects which are tagged with .rdata and when you 
try to dynamically load them -> bang.   I got always this crash when 
GConf loaded gthread.dll.  Now I don't find any 'R' tags in /usr/lib, 
run this: for i in `ls *.dll.a`; do echo $i && nm $i | grep ' R '; done 
in /usr/lib.

That was mysterious for me too, I compiled GConf the first tiome, it 
worked, but I didn't included the old locking patches, so it fails to 
run.  Then I fetched Steve's locking patches and after the second build 
it was broken.  I'm not sure if I updated any package between the two 
builds.

What changed is that there are these .rdata tags in symbols.  That may 
well cause such problems.  Charles explained exactly why the error 
happens and that it must be changed in the source, we should look into 
all the libraries if there are .rdata rtags and then try to patch the 
sources so that gcc puts these symbols in data sections instead.

Yes, I will submit them at first.

Now since Charles has found a workaround and we have the new libtool 
version we can run the apps and debug them.  What to do if you even 
cannot start the application?  The only thing I saw was that loading 
gthread gives my a crash.

Some of the Perl packages are building without modification via cpan 
shell, so I think these should not be included.

I saw it, I had similar problems once, but I cannot remember the actual 
solution.  Are you sure that there is no other Cygwin DLL in memory?
Some commercial applications are installing cygwin1.dll as well!

I make a backup in such cases, `format h:` reinstall all the stuff and 
everytime I'm missing a DLL or a library I pull it out of the backup.

What I also did was to buy some more RAM and I added this to my 
registry, maybe this helps?

I have some spare time the next two - three weeks and then I'm busy at 
end of October.
