From d1840e54a15fc454936cada10cce7fd91d06232b Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Thu, 15 Jul 2021 08:43:01 -0400 Subject: [PATCH] Adding ability to detect non-posix extensions for pthreads Theres a desire to build rngd with musl, which doesn't have all the gnu extensions (but it has some). So test for those. Note, this requires the addition of the USE_EXTENSIONS macro to enable -d_GNU_SOURCE Signed-off-by: Neil Horman [Retrieved from: https://github.com/nhorman/rng-tools/commit/d1840e54a15fc454936cada10cce7fd91d06232b] Signed-off-by: Fabrice Fontaine --- configure.ac | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/configure.ac b/configure.ac index 0fe06fc..de7dca3 100644 --- a/configure.ac +++ b/configure.ac @@ -25,6 +25,7 @@ AC_CANONICAL_TARGET dnl required for broken AX_PTHREAD AM_INIT_AUTOMAKE([foreign]) AC_CONFIG_HEADERS([rng-tools-config.h]) AC_CONFIG_MACRO_DIRS([m4]) +AC_USE_SYSTEM_EXTENSIONS dnl Parse options @@ -100,6 +101,12 @@ AS_IF( ], [AC_MSG_NOTICE([Disabling JITTER entropy source])] ) +AC_CHECK_DECL(pthread_attr_setaffinity_np, + [AC_DEFINE([HAVE_PTHREAD_ATTR_SETAFFINITY], 1,[Set ATTR_SETAFFINITY])], + [ AC_CHECK_DECL(pthread_setaffinity_np, + [AC_DEFINE([HAVE_PTHREAD_SETAFFINITY],1, [Set PTHREAD_SETAFFINITY])], [ AC_MSG_ERROR([Neither pthread_setaffinity_np nor pthread_attr_setaffinity_np found])],[[#include ]]) + ], [[#include ]]) + AS_IF( [ test "x$with_nistbeacon" != "xno"], [
