CADO help

[henryzz]

I have just compiled CADO on WSL. I get an error when running:

I am fairly certain this is a fairly easy error to fix if you know how to. Anyone know how to?

[/CODE]

Looks like you have some misconfigured networking settings. Review the documentation for how to set up multiple computers (including how to only use the local machine).

(Unfortunately I can't be more specific, don't have CADO installed myself currently)

I am not having any joy. I can't even start it as a stand alone server.

I will get back to you later. CADO works fine here but I don't, at present, because I've a bad migraine now.

I just found a way of fixing it. It had to edit /etc/hosts to add 127.0.0.1 JIMMY
I found this by getting a similar error running sudo
Hope you lose your migraine quickly they can be a pain.

I am not certain that it should have been crashing after failing to resolve JIMMY. It knew it could use 127.0.0.1

I was right it was trivial to fix assuming you knew the issue.

Hi, while polyselecting a c225 (https://www.mersenneforum.org/showthread.php?t=28057) I got a strange message from CADO.

Warning:Polynomial Selection (root optimized): File /home/vincent/Bureau/c225/c230.upload/c230.polyselect2.d4x6o9o8.opt_138 contains: # WARNING: the content of the algebraic side of polynomial 4 is not 1 (4). The input polynomial will be divided by its content.

and the poly in question is

should I be concerned?

I've never seen that before, but I don't think it's very concerning; it just means that an algebraic poly was produced where all the coefficients had a common factor, and that factor was divided out.
