Thanks Dubslow, and cool to see the attachment size limit upgrade.

[QUOTE=bsquared;317758]You are free to link to any version of GMP-ECM you like with the ecm_path option in yafu.ini. I have no plans at this point to upgrade the linked-in version of GMP-ECM because nominally it only runs for very small B1's and I wouldn't expect a noticeable difference there.[/QUOTE]
I see, valid point. Maybe when 7.0 and/or GMP 5.1.0 is out then.

[QUOTE=Dubslow;317760]Here's a YAFU 1.33 (for Linux x64) built with GMP-ECM 6.4.3, as attached in the other thread. (Though, as B[sup]2[/sup] just pointed out, after I'd compiled/compressed everything :razz:, YAFU uses an external GMP-ECM binary in almost all cases anyways.)[/QUOTE]
Why do I get "Illegal instruction" when I try to use nfs()?

Can you post details? :razz:

Does your machine have SSE2? YAFU requires it...

[QUOTE=Dubslow;317848]Can you post details? :razz:[/QUOTE]
I'm using a K10-CPU.

I type nfs("number"), in YAFU. When I hit enter it prints "Illegal instruction".
And YAFU is terminated.

I don't think I changed anything except I went from 1.30 to 1.33.

There's nothing in YAFU's nfs code that requires SSE2, but ggnfs does, and perhaps msieve too (it's been awhile since I've browsed the poly select code so I'm not sure there). But in any case a K10 should have sse2. Are you running the 64 bit version on a 32 bit OS?

It's 64 bit.

factor() works.

Is this the binary that Dubslow posted or the stock one from sourceforge? Do you see the same problem in both?

It's the one that Dubslow posted. The one from sourceforge works.

That's not good :razz:

I just tested my copy of that binary, and AFAICT (tested GNFS poly select and GNFS sieving) it works fine.

Here's a test: if your command that's crashing is `./yafu blah blah blah`, please try running `gdb ./yafu blah blah blah`, and then when that program starts, type `run`; when YAFU crashes, type `bt full` and post the output here.

Unless B[sup]2[/sup] has better insight?

Perhaps gcc only compiled it for my architecture? But then the ecm compile of mine you're using wouldn't work either...
