Hi,

You have the same problem as the one I answered to one month ago, on this very list:
  https://sympa.inria.fr/sympa/arc/cado-nfs/2023-07/msg00014.html
  https://sympa.inria.fr/sympa/arc/cado-nfs/2023-07/msg00016.html

Also, could you please avoid posting each message twice?

Objet: [cado-nfs] Supplement to the discrete logarithm problem for quadratic-extended feild

Dear professor:

         I run the example ''./cado-nfs.py 100000000000000000039 -dlp -ell 164354743277891 -gfpext 2'' in params.p2dd20.

get "If you want to compute one or several new target(s), run ./cado-nfs.py /tmp/cado.6sp3cynu/p2dd20.parameters_snapshot.0 target=<target>[,<target>,...]"

but when I run ''./cado-nfs.py /tmp/cado.6sp3cynu/p2dd20.parameters_snapshot.0 target=12345645618974,89465406546598''

Then I get:

Info:Individual logarithm: Starting

Info:Individual logarithm: Now doing descent for target=12345645618974

How should I deal with this problem

I get cado-nfs from Files · master · cado-nfs / cado-nfs · GitLab (inria.fr). version may be 3.0.0.

I installed the ubantu22.0.4 virtual machine on VMware，and use G++ compiler

     Looking forward to hearing from you.
