Discussion related to cado-nfs

[eric.jeancolas@free.fr]

Hi,

First of all, with sudo apt install cmake, I went further on 22.10. I agree 
it is better to keep consistant in packages. I didn't know it was possible to 
install cmake via apt, and for sure, this is a good practice to do so. 
Anyway, we have to do some sudo apt install with m4, libgmp3-dev, etc. So to 
add cmake as a requirement is not a problem.

I went further, but I'm blocked now at this stage :
[  1%] Building CXX object utils/CMakeFiles/utils.dir/params.cpp.o
cc1plus: internal compiler error: Erreur de segmentation

I'll make more tests in the following days. I'll keep you posted.

Best regards.

Objet: Re: [cado-nfs] Compil pb with latest patches Ubuntu 22.04 and 22.10

Hi,

None of these configurations is expected to cause problems, really.

I just tested with ubuntu 22.04.1 and 22.10 (the ubuntu:latest and
ubuntu:rolling containers, more precisely). Compilers version are similar
to what you report. I did not encounter any problem.

There is indeed a recent fix that cures a compiler mishap, and which I
had not yet pushed to master before a few minutes ago (de0d915ea).
However the triggers for that bug were rather recent clang +
system-installed libfmt-dev. Nothing like what you seem to have. So I
doubt that this will solve your problem.

I do notice one thing: you're relying on this weird feature of cado-nfs
that downloads and installs cmake. Really, I'd like to get rid of that
feature, it's a nuisance. It could *maybe* be a cause to your problem.

IOW: sudo apt-install cmake, and get rid of the cado-nfs cruft that
cado-nfs has generated for you. You'll probably be much better off with a
system installed version.

While you're at it, things like libfmt-dev and libhwloc-dev are also nice
to have.

Please tell me if any of the above information helps you find out what is
going on. If not, I would indeed need further information.

E.
