Switching to dynamic linking

I'm building some packages with autoconf and automake, and would like to make sure libraries are dynamically linked (i.e. no stat开发者_如何学Cic links).

How should one set up the autotools to force dynamic library linking?

Something like this comes to mind:

# Makefile.am
lib_LTLIBRARIES = libpart.la
libpart_la_SOURCES = lgpl_chunk.c

bin_PROGRAMS = prop
prop_SOURCES = prop.c
prop_LDADD = libpart.la

And make sure that you always build a shared library. Best by disabling static builds by default,

#configure.ac
AC_DISABLE_STATIC
if test "$enable_static" != "no"; then
  echo "Sorry Dave, I can't let you do that";
  exit 1;
fi; 

You don't necessarily have to rely on autotools for this. You could use dlopen or some other facility to load the dynamic lib.
