From e4a7b344df40b1f4b2e732ddb0d68079ce658d89 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 25 Mar 2015 18:57:36 -0400 Subject: [PATCH] configure: handle clang -nopie argument warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gcc 4.9.2 treats -nopie as an error: cc: error: unrecognized command line option ‘-nopie’ clang 3.5.0 treats -nopie as a warning: clang: warning: argument unused during compilation: '-nopie' The causes ./configure to fail with clang: ERROR: configure test passed without -Werror but failed with -Werror. Make the -nopie test use -Werror so that compile_prog works for both gcc and clang.
