From 99d4c9e26bc3c3736caf7766efd26200c3e899da Mon Sep 17 00:00:00 2001 From: Alberto Bertogli Date: Fri, 24 Jul 2009 20:43:14 -0300 Subject: [PATCH 49/74] libjio: Add a soname to the generated .so This patch adds soname to the generated shared object, so multiple incompatible versions of the library can be installed at the same time. This relies on the compiler using GNU ld, or other linker with a compatible syntax.
