I cloned the repository and then did “git checkout develop”.

VERSION.txt now reads
SageMath version 8.0.beta9, Release Date: 2017-05-31

Is something amiss?

Thanks!

It seems that this happens on several machines:

Error installing package gf2x-1.1.p2

See for example

Upstream is aware of the problem. A new release of gf2x
is getting ready that hopefully will fix the problem.
No ticket for that yet.
This started after I included a fix for bug in
https://trac.sagemath.org/ticket/18882
It may have triggered another bug down the line.

I am also getting this error on my laptop when trying to do an incremental upgrade from beta9.

What is the currently workaround for getting gf2x to build? Is it reverting #18882?

Best,
Travis

Given what I see, you only get this when you set SAGE_TUNE_GF2X=full.
Unsetting SAGE_TUNE_GF2X (which is the default) or putting it to no
will work. At least it looks to me like SAGE_TUNE_GF2X is set to full
from the log, let me know if this assumption is wrong.

I didn't set SAGE_TUNE_GF2X, but it still attempted the tuning even with it unset. However, it built fine when I did export SAGE_TUNE_GF2X=no.

Thanks,

[François Bissey]

There are 3 levels of tuning for gf2x in the sage spkg:
no) no tuning
full) full tuning
*) default if unset.

I thought it was only happening on full. But obviously I am wrong.
The fix must have exposed a further bug that was more prevalent
than I thought.
On my machine I have no problem doing a default tuning or a full
tuning with both gcc and clang. And the test suite passes in full
in all configurations.

But given how widespread this is turning out to be, we would be
better reverting https://trac.sagemath.org/ticket/18882 and
wait for the new release of gf2x. The changes on git master are
big enough that cherry-picking is a difficult option, and the
tuning is massively faster.

I tried reverting #18882, but it didn't seem to work. Yet, I didn't delete the partial install so that might have contributed. I will try again. I also looked at my old build logs and it seems that tuning is the default option as far back as at least 7.6.beta2.

Best,
Travis

[Dima Pasechnik]

this should be fixed by https://trac.sagemath.org/ticket/23225

Hi,

On a different machine (i7-6700HQ + 16 MB RAM), still running Ubuntu 16.04 though, I have the same errors...
(Note: on both machines, 8.0.beta9 was OK).
