Here's what I do for INN. It seems to work well enough. I then use
@LIBTOOLCC@ and @LIBTOOLLD@ (well, a variable set to that) before the
actual compile and link commands where appropriate in Makefiles.
dnl A few tests need to happen before any of the libtool tests in order to
dnl avoid error messages. We therefore lift them up to the top of the file.
AC_PROG_CC
AC_AIX
AC_ISC_POSIX
AC_CANONICAL_HOST
dnl Check to see if the user wants to use libtool. We only invoke the libtool
dnl setup macros if they do. Keep this call together with the libtool setup
dnl so that the arguments to configure will be together in configure --help.
inn_use_libtool=no
AC_ARG_ENABLE(libtool,
[ --enable-libtool Use libtool for lib generation [default=no]],
if test "$enableval" = yes ; then
inn_use_libtool=yes
fi)
if test x"$inn_use_libtool" = xyes ; then
AC_PROG_LIBTOOL
EXTLIB='la'
EXTOBJ='lo'
LIBTOOL='$(top)/libtool'
LIBTOOLCC='$(top)/libtool --mode=compile'
LIBTOOLLD='$(top)/libtool --mode=link'
else
EXTLIB='a'
EXTOBJ='o'
LIBTOOL=''
LIBTOOLCC=''
LIBTOOLLD=''
AC_SUBST(LIBTOOL)
fi
AC_SUBST(EXTLIB)
AC_SUBST(EXTOBJ)
AC_SUBST(LIBTOOLCC)
AC_SUBST(LIBTOOLLD)
