Patch ported from Debian http://anonscm.debian.org/cgit/pkg-gnupg/libgpg-error.git/diff/?id=c3d7571 Signed-off-by: Bernd Kuhls From 91da4f5dbbc9d93975ef9753652a4e71719f9f27 Mon Sep 17 00:00:00 2001 From: Daniel Kahn Gillmor Date: Mon, 16 Mar 2015 13:26:00 -0400 Subject: [LIBGPG-ERROR PATCH] avoid breakage with gcc 5 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * src/Makefile.am: add -P to the C preprocessor when building mkerrcodes.h, to avoid a noisy intermediate pipeline. -- With gcc 5 without this patch, we see many errors like the following: gcc -I. -I. -o mkerrcodes ./mkerrcodes.c In file included from ./mkerrcodes.c:26:0: ./mkerrcodes.h:9:5: error: expected expression before ‘,’ token { , "GPG_ERR_E2BIG" }, ^ ./mkerrcodes.h:10:5: error: expected expression before ‘,’ token { , "GPG_ERR_EACCES" }, ^ This patch cleans up the generated mkerrcodes.h by making the intermediate stage clean for all the versions of gcc i tested (4.x and 5).
