Actually, with LAM's configure script, using --enable-shared will do
the "right" thing for just about every platform (especially all the
x86-based platforms). libtool does a reasonable job of automating this
for the user. If you only want shared library support, I recommend
using
--enable-shared --disable-static
or you will build every file twice (once for PIC code, once for non-PIC
code). Mac OS X is the exception to this rule - you have to leave
static libraries enabled on Mac OS X for very bizarre linker reasons
(note that MPI applications don't have to use static libraries - the
the LAM binaries have to be statically linked).
