Apparently, I may be wrong about this. The problems with Opterons are probably something completely different, and ffcall apparently does work on them (at least as much as GNUstep needs). I'm still interested in peoples' experiences with libffi on Opterons, though. -- Hubert Chathi - Email/Jabber: [EMAIL PROTECTED] - http://www.uhoreg.ca/ PGP/GnuPG key: 1024D/124B61FA (Key available at wwwkeys.pgp.net) Fingerprint: 96C5 012F 5F74 A5F7 1FF7 5291 AF29 C719 124B 61FA ___ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev
Re: amd64 and libffi
I'm seeing a similar failure on my x86_64 (essentially amd64) machine. Could either of you send a backtrace?

I am running GNUstep on amd64, for the time being I had no problems. There were a couple warnings during compile (pointersize differences) of the core packages and Gorm. Probabyl that's something that has to be adressed in future. I don't recall which of ffi or ffcall I used, I will give details to tomorrow, since I don't have an amd64 machine here at home. During the next couple of weeks I intend to start using DO eventually, so I think I will run into trouble regarding amd64 and foreign function calls. How's the actual status of DO in GNUstep?
