Looks like changes made to yafu since r379 might have broken some things for older systems?
(LOL - I just saw your follow up post saying not to use that build... but I'll keep my reply here just for fun):

Hmm... I got a little farther when running tune() on the server in question, but it did still error out at this part:
Code:
starting SIQS on c70: 6470287906463336878241474855987746904297564226439499503918586590778209

I have versions of gmp-ecm and ggnfs that seem to be working fine with an older version of YAFU, so I don't think the error is coming from those, and I don't think the tune() process got to calling any of those external libraries yet anyway.

If push came to shove and I had to compile it, I could probably fire up a test VM on that same server and get VS installed on it...

Any tips on compiling it, if I had to go the long way to get there?
