From 05b6a7550756ffdced25a6c51cf2222bad9e59e7 Mon Sep 17 00:00:00 2001
Message-Id: <05b6a7550756ffdced25a6c51cf2222bad9e59e7.1399285491.git.baruch@tkos.co.il>
From: Baruch Siach <baruch@tkos.co.il>
Date: Mon, 5 May 2014 09:32:23 +0300
Subject: [PATCH] Fix build against older pthreads implementations
Older pthreads implementations like glibc NPTL prior to version 2.12, and
uClibc linuxthreads (both), need _XOPEN_SOURCE to expose
pthread_mutexattr_settype() and THREAD_MUTEX_DEFAULT. The value 600 (SuSv3,
POSIX.1-2001) is equivalent to _POSIX_C_SOURCE 200112L.
Fixes the following build error:
CC compat.lo
compat.c: In function 'p11_mutex_init':
compat.c:164:2: warning: implicit declaration of function 'pthread_mutexattr_settype' [-Wimplicit-function-declaration]
compat.c:164:2: warning: nested extern declaration of 'pthread_mutexattr_settype' [-Wnested-externs]
compat.c:164:36: error: 'PTHREAD_MUTEX_DEFAULT' undeclared (first use in this function)
Patch status: sent upstream
Signed-off-by: Baruch Siach <baruch@tkos.co.il>
