The CI run fails when installing sqlite from Homebrew. Homebrew prints out a warning that macOS 10.12 is unsupported by them and that pull requests are welcome but requests for help are not. |
Homebrew doesn't support 10.12 any more, so build the dependencies without homebrew.
|
Qt5 supports MacOS 10.13 and up, and XCode 11: https://doc.qt.io/qt-5/macos.html |

does it actually do anything?

We have deprecated qt4 support so I don''t think it is worth writing tests. If we get the pyqt5 coverage on azure that seems OK. |

In that case we can speed up the build a little by not installing qt4. |

Why can't we just rely on what's already going on in setupext.py?

I'm sure I added this because of some reason, but the details are lost in the rebases... I'll see if and how the build fails without this step.

The build ends with the error message
error: Failed to download FreeType. Please download one of ['https://downloads.sourceforge.net/project/freetype/freetype2/2.6.1/freetype-2.6.1.tar.gz', 'https://download.savannah.gnu.org/releases/freetype/freetype-2.6.1.tar.gz'] and extract it into build/freetype-2.6.1 at the top-level of the source repository.
I don't know how it is trying to download the file, but perhaps the older MacOS version doesn't support it?

It's just using standard library urllib. Two possibilities, the SSL certificates are old/not found, or the cache location is not writable.
and put that directory in the Travis cache, for perhaps an additional speedup and to reduce the traffic we cause to the download sites
and use two processes for ccache compilation
$HOME/Downloads did not get cached, .cache/matplotlib already is
|
The build is now also faster than any of the Linux builds (but much of that is because we don't run svg or pdf tests on Mac). |

@meeseeksdev backport to v3.3.x |
PR Summary
This sets up Travis so that the Mac tests use XCode 9 on MacOS 10.12.
Homebrew doesn't support this configuration, so we install the library dependencies without it. Tests requiring Qt5 are skipped because Qt5 requires 10.13 or later. We do install Qt4 and at least PySide seems to work, so it is possible to write tests for Qt4.
