From a6dfe2648a39d5fed8de0361aecf0e035ad80222 Mon Sep 17 00:00:00 2001 From: Jim Warner Date: Thu, 6 Jun 2013 00:00:00 -0500 Subject: [PATCH] top: add the major version to dlopen of libnuma soname When the plug-in approach to NUMA support was added, I carelessly employed the compile-time linker convention for naming the library. Technically this then required the 'devel' package for NUMA support to be present for the unqualified soname symlink to be available. Either that or one must have manually created such a symlink. This commit adds the missing major version to dlopen() of libnuma.so.1 so simply having a more likely package such as 'numactl' will enable both '2' & '3' commands.
