From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnout Vandecappelle (Essensium/Mind) Date: Sun, 20 Nov 2016 17:04:41 +0100 Subject: [Buildroot] [PATCH] openblas: disable OpenMP Message-ID: <20161120160441.29150-1-arnout@mind.be> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net 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.
