From: Arnout Vandecappelle Date: Sun, 20 Nov 2016 16:04:41 +0000 (+0100) Subject: openblas: disable OpenMP X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fb45f199e509d05be4bc696b740f995918fe9eb6;p=buildroot.git openblas: disable OpenMP For powerpc (and powerpc only), the openblas build system will enable USE_OPENMP when threads are enabled. But the toolchain wasn't necessarily built with OpenMP support. So explicitly disable OpenMP - for all architectures, not just powerpc, just to keep things simple. We could have autodetected whether OpenMP is available at configure time, but that would be more of a feature patch, it's up to upstream to do that.
