Re: [Schrodinger-devel] [PATCH] [build] Fix autogeneration of liboilarray.c when --disable-shared

[David F. <dav...@wo...>]

Without --enable-shared, libtool doesn't generate symbol lists.  Use
some autogenerated-libtool-internals to sort it out.

Tested with: gcc on linux-amd64, mingw crosscompile, osx-{ppc,intel}
