From 4c28175c430decff429d54867f348f6dbfd5d6e2 Mon Sep 17 00:00:00 2001 From: Curtis Gedak Date: Wed, 1 Jan 2020 13:34:32 -0700 Subject: [PATCH] Remove support for macOS X Sierra (10.12) in Travis CI build The Travis CI builds for macOS X are failing because there are no Homebrew bottles (packages) for macOS X Sierra (10.12). The error message in the Travis CI log is: ... # Upgrade to python 3.x brew upgrade python Warning: You are using macOS 10.12. We (and Apple) do not provide support for this old version. ... Note that by default the Travis CI will terminate a build after 10 minutes if no output has been received. Unfortunately building qt from source code may take hours, so installation using a Homebrew bottle is required. To address this issue, choose a macOS X version that has a Homebrew bottle for qt [1]. [1] https://formulae.brew.sh/formula/qt The homebrew project currently lists having a qt bottle for: - Catalina (10.15) - Mojave (10.14) - High Sierra (10.13) No bottle is listed for macOS Sierra (10.12) In order to support as many versions of macOS X as possible, choose the lowest osx_image value [2] that is currently supported with a homebrew bottle. [2] https://docs.travis-ci.com/user/reference/osx#os-x-version At this time osx_image value xcode9.3 is listed as supporting OS X 10.13. Unfortunately xcode9.3 did not work in the Travis CI build. By following the suggestions for troubleshooting homebrew [3] a discovery was made that a higher value of xcode10.1 was required. [3] https://docs.brew.sh/Troubleshooting Suggestion was to use "brew update" twice and "brew doctor" twice. The messages in the log were as follows: ... Warning: Your Xcode (9.3) is outdated. Please update to Xcode 10.1 (or delete it). ... Now try setting osx_image value to xcode10.1 which is listed as supporting OS X 10.13. --- .travis.yml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/.travis.yml b/.travis.yml index 57e6021..a39e423 100644 --- a/.travis.yml +++ b/.travis.yml @@ -2,7 +2,7 @@ language: generic os: - osx - linux -osx_image: xcode8.3 +osx_image: xcode10.1 sudo: required install: - if [ "$TRAVIS_OS_NAME" = "osx" ]; then package/prepare_osx.sh; fi
