Commit-ID: 39f5704399042fff5f0d5f6af32bbbc3e787a897 Gitweb: http://git.kernel.org/tip/39f5704399042fff5f0d5f6af32bbbc3e787a897 Author: Josh Boyer <jwboyer@xxxxxxxxxxxxxxxxx> AuthorDate: Wed, 11 Feb 2015 11:24:05 -0500 Committer: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx> CommitDate: Wed, 11 Feb 2015 17:38:55 -0300 perf tools: Define _GNU_SOURCE on pthread_attr_setaffinity_np feature check The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE must be defined before pthread.h is included in order to get the proper function declaration. Define this in the Makefile. Without this defined, the feature check fails on a Fedora system with gcc5 and then the perf build later fails with conflicting prototypes for the function.
