From 505be2201377fa347a34b6cb4164c856b55e7484 Mon Sep 17 00:00:00 2001 From: Fabrice Fontaine Date: Thu, 23 Nov 2017 22:47:39 +0100 Subject: [PATCH] Fix pthread_setname_np detection Commit 6617c6f2c8aad041d3428bea11206fd2e61763b1 replaced AC_LINK_IFELSE with AC_COMPILE_IFELSE. This has broken the pthread_setname_np detection as compilation will always succeed even if pthread_setname_np is not available (if the function is not found, a simple warning will be displayed in config.log). The correct fix is to put back AC_LINK_IFELSE with -pthread in LIBS otherwise compilation will fail on toolchain without pthread_setname_np.
