+1 for dropping python 2.7 compatibility It is unfortunate that the wiki makes that promise. But it is a community wiki, and as such I wouldn't consider it an authorative source. Keeping python2 support will be a *lot* of effort, either for the sage project or (if it just refuses to deal with t

Can someone with trac admin access and know-how add a 9.2 milestone, so people can develop for 9.2 if they want to focus on dropping Python 2 support? Meanwhile, 9.1 should include a deprecation warning when people use './configure --with-python=2'. On Sunday, January 5, 2020 at 1:06:21 PM

I think our wiki vetoes that idea. See https://wiki.sagemath.org/Python3-Switch : Compiling with Python 2 After version 9.0, if you really want so, you can still build and use SageMath with *Python 2*, as follows. make configure./configure --with-python=2make build Beware that you will need

Hello, I would like to suggest that the sooner we drop Python 2 support the better. We still need to handle the upgrade to ipython7 and the compatibility with python 3.8. All this will be made very difficult if we insist on maintaining a codebase that is both compatible with python 2 and pytho

2020-01-05 Thread Darij Grinberg
Aha. The build failure was caused by https://trac.sagemath.org/ticket/27444 , exactly as embray's comment:34 suggested. Undoing the 1-line change from that branch to build/pkgs/fflas_ffpack/spkg-install and recompiling fflas_ffpack (sage -f fflas_ffpack) got me through that point. Hope the rest of
