# AC_LIBTOOL_DLOPEN

# AC_LIBTOOL_WIN32_DLL

# This macro should be used if the package has been ported to build
# clean dlls on win32 platforms. Usually this means that any library
# data items are exported with __declspec(dllexport) and imported with
# __declspec(dllimport). If this macro is not used, libtool will assume
# that the package libraries are not dll clean and will build only static
# libraries on win32 hosts.
#
# This macro must be called before AC_PROG_LIBTOOL, and provision must
# be made to pass '-no-undefined' to libtool in link mode from the package
# Makefile. Naturally, if you pass '-no-undefined', you must ensure that
# all the library symbols really are defined at link time!
#
# -----------------------------------------------------------------------------

AC_DISABLE_STATIC() # (forces libtool to build shared
# libraries instead of static ones)
# -----------------------------------------------------------------------------
# AC_PROG_LIBTOOL
#
# Add support for the '--enable-shared' and '--disable-shared'
# configure flags. By default, this macro turns on shared libraries
# if they are available, and also enables static libraries if they
# don't conflict with the shared libraries. You can modify these
# defaults by calling either the AC_DISABLE_SHARED or AC_DISABLE_STATIC
# macros.
#
# Hercules REQUIRES shared libraries (i.e. DLLs), so we do indeed use
# the AC_DISABLE_STATIC macro above.
#
# -----------------------------------------------------------------------------
AC_PROG_LIBTOOL() # (we build libtool for ourselves)
# -----------------------------------------------------------------------------
#
# AC_LIB_LTDL
#
# Even though libltdl is installed together with libtool, you may wish
# to include libltdl in the distribution of your package, for the convenience
# of users of your package that don't have libtool or libltdl installed.
#
# The most simplistic way to add libltdl to your package is to copy the
# source files, 'ltdl.c' and 'ltdl.h', to a source directory withing your
# package and to build and link them along with the rest of your sources.
#
# To do this, you must add a call to the 'AC_LIB_LTDL' macro to your package's
# 'configure.in' to perform the required configure time checks in order that
# 'ltdl.o' is built correctly.
#
# This method does have its problems though: if you try to link the package
# binaries with an installed libltdl, or a library which depends on libltdl,
# you may have problems with duplicate symbol definitions.
#
# In order to enable this flavor of libltdl, you should add the line
# 'AC_LIBLTDL_CONVENIENCE' to your `configure.in', before 'AC_PROG_LIBTOOL'.
#
# In order to select the installable version of libltdl, you should add a
# call of the macro 'AC_LIBLTDL_INSTALLABLE' to your 'configure.in' before
# 'AC_PROG_LIBTOOL'. This macro will check whether libltdl is already
# installed and, if not, request the libltdl embedded in your package to be
# built and installed.
#
# Whatever macro you use, it is up to you to ensure that your 'configure.in'
# will configure libltdl, using 'AC_CONFIG_SUBDIRS', and that your 'Makefile's
# will start sub-makes within libltdl's directory, using automake's SUBDIRS,
# for example. Both macros define the shell variables LIBLTDL, to the link flag
# that you should use to link with libltdl, and LTDLINCL, to the preprocessor
# flag that you should use to compile with programs that include 'ltdl.h'. It
# is up to you to use 'AC_SUBST' to ensure that this variable will be available
# in 'Makefile's, or add them to variables that are 'AC_SUBST'ed by default,
# such as LIBS and CPPFLAGS.
#
# So, when you want to link a program with libltdl, be it a convenience,
# installed or installable library, just compile with '$(LTDLINCL)' and link
# it with '$(LIBLTDL)', using libtool.
#
# You should probably also add 'AC_LIBTOOL_DLOPEN' to your 'configure.in' before
# 'AC_PROG_LIBTOOL', otherwise libtool will assume no dlopening mechanism is
# supported, and revert to dlpreopening, which is probably not what you want.
#
# The following example shows you how to embed the convenience libltdl
# in your package. In order to use the installable variant just replace
# 'AC_LIBLTDL_CONVENIENCE' with 'AC_LIBLTDL_INSTALLABLE'. We assume that libltdl
# was embedded using 'libtoolize --ltdl':
#
# configure.in:
#
# ...
# dnl Enable building of the convenience library
# dnl and set LIBLTDL accordingly
# AC_LIBLTDL_CONVENIENCE
# dnl Substitute LTDLINCL and LIBLTDL in the Makefiles
# AC_SUBST(LTDLINCL)
# AC_SUBST(LIBLTDL)
# dnl Check for dlopen support
# AC_LIBTOOL_DLOPEN
# dnl Configure libtool
# AC_PROG_LIBTOOL
# dnl Configure libltdl
# AC_CONFIG_SUBDIRS(libltdl)
# ...
#
# Makefile.am:
#
# ...
# SUBDIRS = libltdl
#
# INCLUDES = $(LTDLINCL)
#
# myprog_LDFLAGS = -export-dynamic
# # The quotes around -dlopen below fool automake <= 1.4 into accepting it
# myprog_LDADD = $(LIBLTDL) "-dlopen" self "-dlopen" foo1.la
# myprog_DEPENDENCIES = $(LIBLTDL) foo1.la
