From 7f5fec620101dba2e97a08d7e61640aa39a3c3f0 Mon Sep 17 00:00:00 2001 From: Samuel Martin Date: Tue, 13 May 2014 11:11:40 +0200 Subject: [PATCH] clapack: disable on blackfin The "_" symbol prefix added by the blackfin toolchain causes "undefined symbol" build failures when the compiler is trying to link a binary with libblas and/or liblapack. This patch also disables clapack reverse dependencies: armadillo.
