Built from fresh clone of the develop branch on three macOS systems: 10.11.6 (mid-2015 MBP, Quad-core Core i7), 10.13.6 (2017 iMac Pro, 18-core Xeon W), and 10.14.4 (2017 MBP, Quad-core Core i7).

No problems with the builds. Testing (‘ptestlong’) went as follows:

10.11.6: All tests passed!

10.13.6: One test failed:
sage -t --long --warn-long 69.7 src/sage/libs/singular/polynomial.pyx
Passed when run separately.

10.14.4: all tests passed!

On Ubuntu 18.04 running on Xeon E5-2623 + 16 GB RAM:

- python2:

  - incremental build (from 8.8.beta1) completed but (as in Sage 8.8.beta1) with huge number of errors in building the documentation, all with the same message:

     [dochtml] UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 43: ordinal not in range(128)

     The html documentation looks good though.

  - all tests from ptestlong passed

- python3:

  - incremental build (from 8.8.beta1) completed but (as in Sage 8.8.beta1) with huge number of deprecation warnings in building the documentation:

    [dochtml] [combinat ] /home/eric/sage/py3/src/sage_setup/docbuild/ext/sage_autodoc.py:1406: RemovedInSphinx20Warning: formatargspec() is now deprecated.  Please use sphinx.util.inspect.Signature instead.

The html output looks good.

  - all tests from ptest-python3 passed

interesting, do you get any traceback? Where is the é coming from?

[Emmanuel Charpentier]

FWIW, on Debian testing running on core i7 + 16 GB RAM, incrementally (from 8.8.beta1) builds OK, but fails to build its documentation. The doc can be successfully built with the problem described by Eric Gourgoulhon (huge number of failures on "é"). Passes ptestlong with one transient failure on a graphics test in the French sage book.

HTH,

[Eric Gourgoulhon]

Here is some traceback (from Sage 8.8.beta1 where the problem first appeared):

[dochtml] Traceback (most recent call last):

With python2 I can expose these UnicodeEncodeError by inserting "-vv" in SPHINXOPTS in sage/sage_setup/docbuild/build_options.py. I get two

UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 22: ordinal not in range(128)

UnicodeEncodeError: 'ascii' codec can't encode character u'\u250c' in position 22: ordinal not in range(128)

and the docs will not build

UnicodeEncodeError: 'ascii' codec can't encode character u'\xfc' in position 22: ordinal not in range(128)

Error building the documentation.

If anaconda is already installed on my Mac (Mojave, 10.14.4 with Xcode 10.2), there is a problem compiling r-3.5.2.p0. I tried reinstalling anaconda and recompiling but failed with the same error. The good news is that after uninstalling anaconda, compiling sage-8.8.beta2 succeeded.

The crux of the matter seems to be that if anaconda is installed, then I get a message saying that although libcurl is version 7.64.0, it is still somehow not >= 7.22.0:

After uninstalling anaconda, curl-config comes from /usr/bin and everything works fine. This only became a problem with  sage-8.8.beta1 and sage-8.8.beta2. I had earlier compiled sage-8.8.beta0 with no problems despite having anaconda installed.
