#
# 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=

# 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.
