# 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=

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=

# dependencies to other libraries.

# 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.
