From 0f48e046f44624f4d4d8255ac5bd26397a38f16c Mon Sep 17 00:00:00 2001 From: Keshav Kini Date: Sun, 23 Feb 2020 14:09:30 -0800 Subject: [PATCH] Support shared library build Patch taken from [the ACL2 Books documentation][1]. - Add " -fPIC" to the CXXFLAGS to build position-independent code, required for shared libraries. - Add the line "export CXXFLAGS" below the setting of CXXFLAGS, so that those flags apply to the recursive make of the core solver library. - Fix a typo: replace the occurrence of "CXXLAGS" with "CXXFLAGS".
