File 0022-add-__acl_-prefixes-to-internal-symbols.patch of Package acl
From a2c4d71c2e84419a49db503ed59de4d3d1dca7dd Mon Sep 17 00:00:00 2001 From: Mike Frysinger <vapier@gentoo.org> Date: Tue, 12 Aug 2014 08:37:25 -0400 Subject: [PATCH 22/34] add __acl_ prefixes to internal symbols When static linking libacl, people sometimes run into symbol collisions because their own code defines symbols like "quote". So for acl internal symbols, use an __acl_ prefix. --- exports | 12 ++---------- include/misc.h | 8 ++++---- libacl/__acl_to_any_text.c | 4 ++-- libacl/acl_from_text.c | 4 ++-- libmisc/high_water_alloc.c | 2 +- libmisc/next_line.c | 6 +++--- libmisc/quote.c | 4 ++-- libmisc/unquote.c | 2 +- tools/getfacl.c | 4 ++-- tools/parse.c | 14 +++++++------- tools/setfacl.c | 4 ++-- 11 files changed, 28 insertions(+), 36 deletions(-) diff --git a/exports b/exports index 7d8e69e..bf15d84 100644 --- a/exports +++ b/exports @@ -59,22 +59,14 @@ ACL_1.0 { acl_to_any_text;
