 #
 # Helper makefile to link shared libraries in a portable way.
 # This is much simpler than libtool, and hopefully not too error-prone.
 #
 # The following variables need to be set on the command line to build
 # properly

 # CC contains the current compiler.  This one MUST be defined
 CC=cc
 CFLAGS=$(CFLAG)
 # LDFLAGS contains flags to be used when temporary object files (when building
 # shared libraries) are created, or when an application is linked.
 # SHARED_LDFLAGS contains flags to be used when the shared library is created.
 LDFLAGS=
 SHARED_LDFLAGS=

 NM=nm

 # LIBNAME contains just the name of the library, without prefix ("lib"
 # on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so,
 # .dll, ...).  This one MUST have a value when using this makefile to
 # build shared libraries.
 # For example, to build libfoo.so, you need to do the following:
 #LIBNAME=foo
 LIBNAME=

 # APPNAME contains just the name of the application, without suffix (""
 # on Unix, ".exe" on Windows, ...).  This one MUST have a value when using
 # this makefile to build applications.
 # For example, to build foo, you need to do the following:
 #APPNAME=foo
 APPNAME=

 # OBJECTS contains all the object files to link together into the application.
 # This must contain at least one object file.
 #OBJECTS=foo.o
 OBJECTS=

 # LIBEXTRAS contains extra modules to link together with the library.
 # For example, if a second library, say libbar.a needs to be linked into
 # libfoo.so, you need to do the following:
 #LIBEXTRAS=libbar.a
 # Note that this MUST be used when using the link_o targets, to hold the
 # names of all object files that go into the target library.
 LIBEXTRAS=

 # LIBVERSION contains the current version of the library.
 # For example, to build libfoo.so.1.2, you need to do the following:
 #LIBVERSION=1.2
 LIBVERSION=

 # LIBCOMPATVERSIONS contains the compatibility versions (a list) of
 # the library.  They MUST be in decreasing order.
 # For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2
 # and libfoo.so.1, you need to do the following:
 #LIBCOMPATVERSIONS=1.2 1
 # Note that on systems that use sonames, the last number will appear as
 # part of it.
 # It's also possible, for systems that support it (Tru64, for example),
 # to add extra compatibility info with more precision, by adding a second
 # list of versions, separated from the first with a semicolon, like this:
 #LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0
 LIBCOMPATVERSIONS=

 # LIBDEPS contains all the flags necessary to cover all necessary
 # dependencies to other libraries.
 LIBDEPS=

 #------------------------------------------------------------------------------
 # The rest is private to this makefile.

 # For Darwin AKA Mac OS/X (dyld)
 # Originally link_o.darwin produced .so, because it was hard-coded
 # in dso_dlfcn module. At later point dso_dlfcn switched to .dylib
 # extension in order to allow for run-time linking with vendor-
 # supplied shared libraries such as libz, so that link_o.darwin had
 # to be harmonized with it. This caused minor controversy, because
 # it was believed that dlopen can't be used to dynamically load
 # .dylib-s, only so called bundle modules (ones linked with -bundle
 # flag). The belief seems to be originating from pre-10.4 release,
 # where dlfcn functionality was emulated by dlcompat add-on. In
 # 10.4 dlopen was rewritten as native part of dyld and is documented
 # to be capable of loading both dynamic libraries and bundles. In
 # order to provide compatibility with pre-10.4 dlopen, modules are
 # linked with -bundle flag, which makes .dylib extension misleading.
 # It works, because dlopen is [and always was] extension-agnostic.
 # Alternative to this heuristic approach is to develop specific
 # MacOS X dso module relying on whichever "native" dyld interface.

	# Helper makefile to link shared libraries in a portable way.
	# This is much simpler than libtool, and hopefully not too error-prone.
	#
	# The following variables need to be set on the command line to build
	# properly

	# CC contains the current compiler. This one MUST be defined
	CC=cc
	CFLAGS=$(CFLAG)
	# LDFLAGS contains flags to be used when temporary object files (when building
	# shared libraries) are created, or when an application is linked.
	# SHARED_LDFLAGS contains flags to be used when the shared library is created.
	LDFLAGS=
	SHARED_LDFLAGS=

	NM=nm

	# LIBNAME contains just the name of the library, without prefix ("lib"
	# on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so,
	# .dll, ...). This one MUST have a value when using this makefile to
	# build shared libraries.
	# For example, to build libfoo.so, you need to do the following:
	#LIBNAME=foo
	LIBNAME=

	# APPNAME contains just the name of the application, without suffix (""
	# on Unix, ".exe" on Windows, ...). This one MUST have a value when using
	# this makefile to build applications.
	# For example, to build foo, you need to do the following:
	#APPNAME=foo
	APPNAME=

	# OBJECTS contains all the object files to link together into the application.
	# This must contain at least one object file.
	#OBJECTS=foo.o
	OBJECTS=

	# LIBEXTRAS contains extra modules to link together with the library.
	# For example, if a second library, say libbar.a needs to be linked into
	# libfoo.so, you need to do the following:
	#LIBEXTRAS=libbar.a
	# Note that this MUST be used when using the link_o targets, to hold the
	# names of all object files that go into the target library.
	LIBEXTRAS=

	# LIBVERSION contains the current version of the library.
	# For example, to build libfoo.so.1.2, you need to do the following:
	#LIBVERSION=1.2
	LIBVERSION=

	# LIBCOMPATVERSIONS contains the compatibility versions (a list) of
	# the library. They MUST be in decreasing order.
	# For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2
	# and libfoo.so.1, you need to do the following:
	#LIBCOMPATVERSIONS=1.2 1
	# Note that on systems that use sonames, the last number will appear as
	# part of it.
	# It's also possible, for systems that support it (Tru64, for example),
	# to add extra compatibility info with more precision, by adding a second
	# list of versions, separated from the first with a semicolon, like this:
	#LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0
	LIBCOMPATVERSIONS=

	# LIBDEPS contains all the flags necessary to cover all necessary
	# dependencies to other libraries.
	LIBDEPS=

	# For Darwin AKA Mac OS/X (dyld)
	# Originally link_o.darwin produced .so, because it was hard-coded
	# in dso_dlfcn module. At later point dso_dlfcn switched to .dylib
	# extension in order to allow for run-time linking with vendor-
	# supplied shared libraries such as libz, so that link_o.darwin had
	# to be harmonized with it. This caused minor controversy, because
	# it was believed that dlopen can't be used to dynamically load
	# .dylib-s, only so called bundle modules (ones linked with -bundle
	# flag). The belief seems to be originating from pre-10.4 release,
	# where dlfcn functionality was emulated by dlcompat add-on. In
	# 10.4 dlopen was rewritten as native part of dyld and is documented
	# to be capable of loading both dynamic libraries and bundles. In
	# order to provide compatibility with pre-10.4 dlopen, modules are
	# linked with -bundle flag, which makes .dylib extension misleading.
	# It works, because dlopen is [and always was] extension-agnostic.
	# Alternative to this heuristic approach is to develop specific
	# MacOS X dso module relying on whichever "native" dyld interface.
