Discussion related to cado-nfs

Dear Paul Zimmermann.

It is glad for me to get your reply. 

After your suggestion, i avoid the runtime error.

I am very happy to have made such great progress.

As we all know, the element in Fp^2 is a polynomial, such as a in Fp^2, well the a = a0 + a1x, (a0, a1 in Fp). So if I want to solve the DLP in Fp^2, such as a^k = b (mod x^2+1), where x^2+1 is Irreducible polynomials, how do i set the parameters, just like a , b both are polynomials for CADO-NFS?

It make me very confused, i hope your can get me some ideas.

Thanks a lot!

Best Wish！

In a lucky time, I have searched the cado-nfs website and found it can use to
solve the dlp.
Unfortunately, i do not find the doc for how to using it.
It just has a README.dlp, and i follow the step one by one. But i get runtime
error always.

Such as : ./cado-nfs.py 100000000000000000039 -dlp  -ell 164354743277891
-gfpext 2
after this command, i would get an error : can not find polyselect_gfpn
executable program .etc.

did you try "make polyselect_gfpn"?
