For me,
x86-64-v4
does not work: The built programs crash in the polynomial selection stage for a simple 90-digit factorization test. I triedx86-64-v3
which did not work either.However,
-march=native
and-march=sandybridge
do work for me. My build machine has Xeon E5-2670 which aresandybridge
plus AES. It has AVX, but not AVX2.If
sandybridge
does not work for you even ifx86-64-v4
does, I suppose that the specified-march
must be close to-march=native
. Which would make-march=native
the only sensible choice (and the only one consistent with morearch
entries thanx86_64
), but then the built package will not be usable on older-generation platforms.There is a related issue and a related patchset.
By the way, I have chosen to also set
CXXFLAGS
and delete other-march

@Dylan14 thank you for your feedback, it seems the current version of cado-nfs uses Intel intrinsics that depend on very recent versions of the AVX instruction set on x86_64.
For now, I found out what I think the baseline architecture to have those instructions is, so that binary packages built with this PKGBUILD can still be somewhat redistributable (although owners of older x86_64 CPUs are screwed for now).
When I am a little less busy I am gonna check the build system to see if there's some flag to enable more portable code to support those older architectures.

@Dylan14 could you please compile the current PKGBUILD with
LC_ALL=C makepkg -L
and send me the resulting log file?Dylan14 commented on 2021-08-11 01:15 (UTC)
@Aquilalrreale - no changes to my /etc/makepkg.conf.
AquilaIrreale commented on 2021-08-10 21:46 (UTC)
@Dylan14 are you building the package with the standard /etc/makepkg.conf or have you made changes to it? In a regular Arch's makepkg.conf -march should be set by default to x86_64, which I believe matches -march=auto on your CPU platfom. Can you double-check your config file is not setting it wrong it in the first place? Overriding this specific compiler flag inside the build script is usually not good practice.

As provided the package fails to build on my AMD Ryzen 7 3700 laptop, but if the following lines are added to the build() function prior to make:
CFLAGS=-march=native
CXXFLAGS=-march=native
the package builds successfully.

Hello, I took charge of maintaining this package for the time being. It should now be in a usable state once again.
@ccorn thank you for contributing your patch!
Have a nice day

I have made some contemporary updates in my checkout.

package no longer builds. looks like the git repo has been moved to https://gitlab.inria.fr/cado-nfs/cado-nfs.git.
