4Subject: [PATCH] Support shared library build
5
6Patch taken from [the ACL2 Books documentation][1].
7
8- Add " -fPIC" to the CXXFLAGS to build position-independent code,
9 required for shared libraries.
10
11- Add the line "export CXXFLAGS" below the setting of CXXFLAGS, so that
12 those flags apply to the recursive make of the core solver library.
13
14- Fix a typo: replace the occurrence of "CXXLAGS" with "CXXFLAGS".
