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".
