Hi all, out of boredom I did the first steps to port trinity to PA-RISC. The second patch is needed to get it compile, but since those headers are apparently not needed on other archs I suspect something is wrong with the PA-RISC headers. The implementation for some syscalls is missing, I just picked up what was available by default. Also everything currently is 32 bit. In contrast to what other archs do there currently is only a 32 bit userspace on PA-RISC, but there are many systems with a 64 bit userspace. I have the hope that one of the usual suspects would use this to hammer on the kernel and fix the fallout. ;) Eike
