Could you please try this with the updated tachyon package from 5281?

Replying to mhampton:

Could you please try this with the updated tachyon package from 5281?

Sure. I'm at a Starbucks cafe now, so will try later. The RS/6000 is switched off now, so I can't remotely access it.

comment:3 Changed 11 years ago by drkirkby

There are two reasons this is not working.

  • There's nothing in SPKG.txt to handle the case of AIX
  • There's no target in the file Make-arch that will work with a generic compiler on AIX. The targets all assume the use of IBM's compiler.

Two targets will be added for AIX, and since HP-UX will suffer the same problem, another two targets will be added for HP-UX. These 4 targets are:

  • aix-generic
  • aix-generic-thr
  • hpux-generic
  • hpux-generic-thr

We might as well try building with the threaded versions (aix-generic-thr and hpux-generic-thr) on both AIX and HP-UX.

comment:4 Changed 11 years ago by drkirkby

I forgot to say, these 4 targets can be added to the Tachyon upgrade ticket #5281, so I am not intending to add a patch here, but rather this ticket can be closed when #5281 is closed. This assumes #5281 does not drag on for ages, as the ticket has been open for 20 months! If that ticket drags on and on, then I'll add patches to this ticket.
