Now it's giving me a whole lot of readouts like this one:

Is that good?

Yes - that's now looking for polynomials.

[quote=miklin;213144]I so think that it is necessary to add simply check presence of programs in the ways specified by the user. If all normally to continue that script work if there is no that to give out an error message.[/quote]

It is already designed to do this when CHECK_BINARIES is set to True.

I just checked this by deleting MSIEVE in my setup and it works fine for me.

Thanks for all your help guys, especially Miklin, Brian and andi.

Here that at me it turns out with removed msieve
On it also has written, it needs to be checked up.
For me it not actually is this check or it is not present. But here is how time this case has shown that check does not work.

This is a bug carried over from the original Perl script. It seems that some polynomial processing with msieve has been added before the binary checks are done.

I have revamped the binary checking in version 68 of the script that is now available at:

[URL]http://www.gladman.plushost.co.uk/oldsite/computing/factmsieve.py.zip[/URL]

This also includes a few other minor changes to ensure that the script exits gracefully under some obscure error conditions.

It should also work with Python 2.6, 2.7 and 3.1

Thanks a lot.

I will try it soon.

Is it possible to sieve on both sides ( -a and -r) ?
Can i change -a to -r in the script (maybe in Line 655 from -a to -r) ?
It would be a nice option to sieve on both sides automatically.

So far, so good, but I did have one more question. How does one go about manually setting the polynomial for SNFS?

[quote=ThomRuley;213394]So far, so good, but I did have one more question. How does one go about manually setting the polynomial for SNFS?[/quote]
E.g. save the poly in example.poly and run "factmsieve.py example".
