Thanks, Volker, for the new rc.

Tests for Linux and macOS have completed at https://github.com/mkoeppe/sage/actions/runs/87839006

All platforms/system configurations except for the following ones build without reproducible errors.

fedora-32: See my message in sage-devel, https://trac.sagemath.org/ticket/29456

conda-forge-macos: Runtime linker error during docbuild, https://trac.sagemath.org/ticket/29574

conda-forge-ubuntu: https://trac.sagemath.org/ticket/29327

There are sporadic errors due to race conditions in the build; in this run, for debian-sid-standard-python2; see https://trac.sagemath.org/ticket/29585

On more platforms/system configurations, there are various doctest errors. See logs at https://github.com/mkoeppe/sage/actions/runs/87839006

Tests for optional packages run at https://github.com/mkoeppe/sage/actions/runs/87839030

The build tests for Cygwin on GitHub Actions are not reliable yet. Reports from Sage developers who use Cygwin would be valuable.

I am now using

./configure --enable-silent-rules

instead of

export V=0

and it seems not to work as make is full verbose now. Am I doing something wrong?

[Matthias Köppe]

Implementing this feature is the task of ticket https://trac.sagemath.org/ticket/21589 (Allow users to make `make V=0` the default by using `./configure --enable-silent-rules`).

[Sébastien Labbé]

Ok, I see, I thought it was in already. Maybe that's the reason why my make finishes with an error. Let me try to run make again without that option. Will report later.

[Sébastien Labbé]

It seems that if I do

./configure  --enable-beautifulsoup4

or

./configure  --enable-pyopenssl

I get

make[3]: ***  Aucune règle pour fabriquer la cible « /home/slabbe/GitBox/sage/local/var/lib
/sage/installed/beautifulsoup4-none », nécessaire pour « all-sage ». Arrêt.
make[3]: *** Attente des tâches non terminées....
...

make[3]: ***  Aucune règle pour fabriquer la cible « /home/slabbe/GitBox/sage/local/var/lib/sage/installed/pyopenssl-none », nécessaire pour « all-sage ». Arrêt.

...

and make stops with an error. Now trying without   --enable-pyopenssl   --enable-beautifulsoup4.

[Sébastien Labbé]

Using the following configuration:

$ head config.log
...

  $ ./configure --enable-experimental-packages --enable-download-from-upstream-url --enable-ccache --enable-dot2tex --enable-rst2ipynb --enable-openssl --enable-cbc --enable-cryptominisat --enable-pycosat --enable-glucose --enable-sage_numerical_backends_coin --enable-sage_numerical_backends_cplex --enable-sage_numerical_backends_gurobi --enable-pynormaliz --enable-latte_int --enable-awali --enable-fricas
...

Thus after removing  --enable-beautifulsoup4 and --enable-pyopenssl, runing make works.

Running test including optional and external packages, I get

Using --optional=4ti2,cbc,ccache,cryptominisat,dot2tex,e_antic,external,fricas,glucose,latte_int,lidia,lrslib,memlimit,normaliz,notedown,openssl,pandoc_attributes,pycosat,pynormaliz,rst2ipynb,sage,sage_numerical_backends_coin,sage_numerical_backends_cplex,sage_numerical_backends_gurobi

Thanks for catching this. This is now https://trac.sagemath.org/ticket/29626

Built from a fresh clone of the develop branch, on three macOS systems: 10.13.6 (2017 iMac Pro, 18-core Xeon W); 10.14.6 (2017 MBP, Quad-core Core i7); and 10.15.4 (2019 MBP, 9-core Core i9).

On each of the systems, there were no problems with the build, and all tests (‘ptestlong’) passed!
