PhiloLogic: Ubuntu 64 bit compilation failure

Damir Cavar reports:

After evaluations with various Linux distributions we came to the conclusion: Philologic index generation (the C-code) breaks on 64-bit (various versions) with a segmentation fault. We didn't manage to let it run in a 32-bit changeroot environment on Ubuntu and Debian.

It works perfectly well on the newest release of the 32-bit Ubuntu server, and also on 32-bit Debian Lenny. On a 32-bit system the default is most likely that one has a memory limitation, i.e. max. 3.5 GB RAM, even though there might be more RAM available physically. If you install the Ubuntu "server kernel" on a 32-bit system, you get large memory support (i.e. more than 3.5 or 4 GB RAM), i.e. you need a PAE enabled kernel. On Debian it is the bigmem kernel you need to install. A 32-bit system is somewhat slower, there are various other disadvantages (if one uses other code or software that makes use of advanced 64-bit CPU features), but, well, we seem to have no other choice now for a solution with Philologic right now.

We have a version running, now on Debian Lenny with the bigmem kernel, and we're putting the bits and pieces together, i.e. our Croatian localization, some scripts for statistics etc. Once this is up, I'll place some more docu, scripts, localizations and adaptations at the Croatian Language Corpus site: http://riznica.ihjj.hr/ (this is still the old system, we are just migrating the infrastructure to new servers, using Lenny)

More can soon be found on the pages of the Linguistics dept. at the University of Zadar: http://ling.unizd.hr/

Should somebody have a fix for a 64-bit Linux environment, hints would be very much appreciated.
