From 176441bfb58d8833640300d8db67ef8d7eee56ca Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?SZEDER=20G=C3=A1bor?= Date: Wed, 27 Nov 2019 17:24:16 +0100 Subject: [PATCH] ci: build Git with GCC 9 in the 'osx-gcc' build job MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Our 'osx-gcc' build job on Travis CI relied on GCC 8 being installed (but not linked) in the image we use [1]. Alas, since the last update of this image a few days ago this is not the case anymore, and now it contains GCC 9 (installed and linked) instead of GCC 8. The results are failed 'osx-gcc' jobs, because they can't find the 'gcc-8' command [2]. Let's move on to use GCC 9, with hopefully better error reporting and improved -Wfoo flags and what not. On Travis CI this has the benefit that we can spare a few seconds while installing dependencies, because it already comes pre-installed, at least for now. The Azure Pipelines OSX image doesn't include GCC, so we have to install it ourselves anyway, and then we might as well install the newer version. In a vain attempt I tried to future-proof this a bit: - Install 'gcc@9' specifically, so we'll still get what we want even after GCC 10 comes out, and the "plain" 'gcc' package starts to refer to 'gcc@10'. - Run both 'brew install gcc@9' and 'brew link gcc@9'. If 'gcc@9' is already installed and linked, then both commands are noop and exit with success. But as we saw in the past, sometimes the image contains the expected GCC package installed but not linked, so maybe it will happen again in the future as well. In that case 'brew install' is still a noop, and instructs the user to run 'brew link' instead, so that's what we'll do. And if 'gcc@9' is not installed, then 'brew install' will install it, and the subsequent 'brew link' becomes a noop. An additional benefit of this patch is that from now on we won't unnecessarily install GCC and its dependencies in the 'osx-clang' jobs on Azure Pipelines.
