2015-09-17tools build: Add test for presence of numa_num_possible_cpus() in libnumaArnaldo Carvalho de Melo1-0/+6
The existing numa test checks only if numa.h and numa_available() are present, but that can be satisfied with an old libnuma that is not enough for the 'perf bench numa' entry, so add a test to check for that: [acme@rhel5 linux]$ make NO_AUXTRACE=1 NO_LIBPERL=1 -C tools/perf O=/tmp/build/perf install-bin make: Entering directory `/home/acme/git/linux/tools/perf' BUILD: Doing 'make -j2' parallel build Auto-detecting system features: ... libelf: [ on ] ... libnuma: [ on ] ... numa_num_possible_cpus: [ OFF ] ... libperl: [ on ] <SNIP> config/Makefile:577: Old numa library found, disables 'perf bench numa mem' benchmark, please install numactl-devel/libnuma-devel/libnuma-dev >= 2.0.8 INSTALL binaries <SNIP> This fixes the build on old systems such as RHEL/CentOS 5.11.
