1# 2# Helper makefile to link shared libraries in a portable way. 3# This is much simpler than libtool, and hopefully not too error-prone. 4# 5# The following variables need to be set on the command line to build 6# properly 7 8# CC contains the current compiler. This one MUST be defined 9CC=cc 10CFLAGS=$(CFLAG) 11# LDFLAGS contains flags to be used when temporary object files (when building 12# shared libraries) are created, or when an application is linked. 13# SHARED_LDFLAGS contains flags to be used when the shared library is created. 14LDFLAGS= 15SHARED_LDFLAGS= 16 17NM=nm 18 19# LIBNAME contains just the name of the library, without prefix ("lib" 20# on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so, 21# .dll, ...). This one MUST have a value when using this makefile to 22# build shared libraries. 23# For example, to build libfoo.so, you need to do the following: 24#LIBNAME=foo 25LIBNAME= 26 27# APPNAME contains just the name of the application, without suffix ("" 28# on Unix, ".exe" on Windows, ...). This one MUST have a value when using 29# this makefile to build applications. 30# For example, to build foo, you need to do the following: 31#APPNAME=foo 32APPNAME= 33 34# OBJECTS contains all the object files to link together into the application. 35# This must contain at least one object file. 36#OBJECTS=foo.o 37OBJECTS= 38 39# LIBEXTRAS contains extra modules to link together with the library. 40# For example, if a second library, say libbar.a needs to be linked into 41# libfoo.so, you need to do the following: 42#LIBEXTRAS=libbar.a 43# Note that this MUST be used when using the link_o targets, to hold the 44# names of all object files that go into the target library. 45LIBEXTRAS= 46 47# LIBVERSION contains the current version of the library. 48# For example, to build libfoo.so.1.2, you need to do the following: 49#LIBVERSION=1.2 50LIBVERSION= 51 52# LIBCOMPATVERSIONS contains the compatibility versions (a list) of 53# the library. They MUST be in decreasing order. 54# For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2 55# and libfoo.so.1, you need to do the following: 56#LIBCOMPATVERSIONS=1.2 1 57# Note that on systems that use sonames, the last number will appear as 58# part of it. 59# It's also possible, for systems that support it (Tru64, for example), 60# to add extra compatibility info with more precision, by adding a second 61# list of versions, separated from the first with a semicolon, like this: 62#LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0 63LIBCOMPATVERSIONS= 64 65# LIBDEPS contains all the flags necessary to cover all necessary 66# dependencies to other libraries. 67LIBDEPS= 68 69#------------------------------------------------------------------------------ 70# The rest is private to this makefile. 71 72SET_X=: 73#SET_X=set -x 74 75top: 76 echo "Trying to use this makefile interactively?

This caused minor controversy, because 215# it was believed that dlopen can't be used to dynamically load 216# .dylib-s, only so called bundle modules (ones linked with -bundle 217# flag). The belief seems to be originating from pre-10.4 release, 218# where dlfcn functionality was emulated by dlcompat add-on. In 219# 10.4 dlopen was rewritten as native part of dyld and is documented 220# to be capable of loading both dynamic libraries and bundles. In 221# order to provide compatibility with pre-10.4 dlopen, modules are 222# linked with -bundle flag, which makes .dylib extension misleading. 223# It works, because dlopen is [and always was] extension-agnostic. 224# Alternative to this heuristic approach is to develop specific 225# MacOS X dso module relying on whichever "native" dyld interface. 226link_o.darwin: 227 @ $(CALC_VERSIONS);
