From db221e66d8117f810c8046ce42c156580e4292aa Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Mon, 28 Aug 2017 12:25:45 +0200 Subject: [PATCH] tests/libqtest: Use a proper error message if QTEST_QEMU_BINARY is missing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The user can currently still cause an abort() if running certain tests (like the prom-env-test) without setting the QTEST_QEMU_BINARY first. A similar problem has been fixed with commit 7c933ad61b8f3f51337 already, but forgot to also take care of the qtest_get_arch() function, so let's introduce a proper wrapper around getenv("QTEST_QEMU_BINARY") that can be used in both locations now.
