Thanks Volker for preparing the release.

All tests pass on debian buster, except

sage -t --long --random-seed=146168601452887490256495561253701871534 src/sage/tests/cmdline.py  # 3 doctests failed                                                               

as squlite executable is not available.

The sqlite doctest failure is tracked at https://trac.sagemath.org/ticket/29092

Are you mixing in conda libraries?
Unless this is a conda build, this most probably won't work.

If it's not a conda build then /usr/local/anaconda3/bin should not
be in your PATH, but it seems it is.

Thanks Dima, removing anacoda, The first built on Mac OS 12.1 worked, with python 3.10.1.

Adding $(PYTHON_TOOLCHAIN) to the cryptominisat dependencies fixed the build failure that I encountered.

[Marc Culler]

My attempt to build rc2 on macOS with arm CPU failed with this error:

Installing cryptominisat-5.6.8
/private/var/tmp/sage-9.5-current/local/var/lib/sage/venv-python3.9.9/bin/python3: No module named pip

Maybe a pip dependency is missing now for cryptominisat?

Thanks Volker for this new release candidate.

On Cygwin 3.3.3-1 on Windows 10, build fails for me while trying
to build `sagemath_doc_html-none`, with or without ticket #33078,
as it has for the last few development versions. Logs:

- https://aij.ovh/sage/logs/slel-2022-01-17-cyg-sage-9-5-c2-33078.zip
- https://aij.ovh/sage/logs/slel-2022-01-17-cyg-sage-9-5-c2-fresh-clone-000.zip

Others have reported success building on Cygwin though,
so I guess I should clean up my Cygwin: maybe uninstall
some packages that are installed but not needed for Sage;
or reinstall Cygwin from scratch.

But I see Sage 9.5.rc3 is out, I'll try that one too. --Samuel

I have resolved all of the issues I know of in the binary prelease of sage 9.5 https://github.com/3-manifolds/Sage_macOS/releases/download/v1.3-rc1/SageMath-9.5_arm64.dmg .

I switched to using the homebrew version of gfortran-11.  That resolved the crash when importing sage.manifolds.manifold (which was actually happening when importing the scpy integration module.)  I believe that the problem was that the other gfortran compiler implements fortran 2018 and some of the scipy modules are not compliant with that.

I also added a copy of the gfortran runtime, suitably adjusted to work in the Sage framework in the app bundle.

Matthias, I think you should revise your recommendation so it specifies the homebrew gfortran-11.

[Matthias Köppe]

Thanks Marc, I have updated https://wiki.sagemath.org/ReleaseTours/sage-9.5#Sources 

[Marc Culler]

Thanks, Matthias.  It is actually 9.5.rc2 now.
