From 3b68fb57c938af3948ae4c2da61501183fbef649 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Petr=20=C5=A0tetiar?= Date: Wed, 20 Mar 2019 09:52:58 +0100 Subject: [PATCH] build: cleanup possibly dangling Python 2 host symlink MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When bumping buildroot to Python 3, we need to assure, that Python symlink in staging bin directory points to Python >= 3.5 as well. We can't rely completly just on SetupHostCommand as its executed only in cases when the $(STAGING_DIR_HOST)/bin/python doesn't already exist, so we need to remove it before running SetupHostCommand.
