From d374a61bb702a8ae13699dfbdcbd819c78095cd5 Mon Sep 17 00:00:00 2001 From: "Dr. Matthias St. Pierre" Date: Tue, 23 Jul 2019 20:54:03 +0200 Subject: [PATCH] Configure: clang: add -Wno-unknown-warning-option Fixes travis build errors due to clang error: unknown warning option '-Wno-extended-offsetof' It seems like '-Wextended-offsetof' was removed from clang in version 6.0.0, (see [1], [2]). While gcc ignores unknown options of the type '-Wno-xxx', clang by default issues a warning [-Wunknown-warning-option] (see [3]), which together with '-Werror' causes the build to fail. This commit adds the '-Wno-unknown-warning-option' option to make clang behave more relaxed like gcc.
