correct what i said above: ldconfig does work, it automatically makes a link: libopenblas.so.0 -> libopenblas_nehalemp-r0.2.9.rc2.so
but what i need is libblas.so.3, so i tried several ways 1. create a file called libblas.so.3, then ldconfig. 2. create a file called libblas.so.3.0 then ldconfig i hope ldconfig will generate a link file called libblas.so.3, but it seems libblas.so.3 is ignored by ldconfig -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/breeze-DGEMM-slow-in-spark-tp5950p6002.html Sent from the Apache Spark User List mailing list archive at Nabble.com.
