[Demexp-dev] Compilation of demexp

[Sylvain Chevillard]

Hello guys.

I'm encountering problems during the compilation of demexp.

I had first some problems with a dependency of demexp : Cduce. I were 
using an old CVS version of Ocaml 3.09 and the compilation of Cduce 
failed when it tried to create the first "pack".
A bit of searches later, I understood that it came from a problem with 
OCaml 3.09 overs powerpc. I installed a new version of Ocaml and 
re-install everything. Cduce compiled without any new problem.

Now, it is Demexp itself which refuses to compile. Everything gets fine 
until it tries to link the object code. It seems to be related with 
Cduce again.
Have a look :

Error during linking
make: *** [srv/demexp-server] Error 2
rm srv/xml.cdo

I'm using the official distribution of Ocaml 3.09.1 downloaded from 
Ocaml's site and compiled from sources over a Powerbook (powerpc G4) 
under Mac OS X 10.3.9, Cduce 0.4.0 downloaded from 
http://www.cduce.org/download/cduce-0.4.0.tar.gz and demexp 0.7 
downloaded from http://www.linux-france.org/~dmentre/demexp/latest-src

Any idea ?
