2 # Helper makefile to link shared libraries in a portable way.
3 # This is much simpler than libtool, and hopefully not too error-prone.
5 # The following variables need to be set on the command line to build
8 # CC contains the current compiler. This one MUST be defined
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.
15 SHARED_LDFLAGS=$(SHARED_LDFLAG)
17 # SHARED_RCFLAGS are flags used with windres, i.e. when build for Cygwin
19 SHARED_RCFLAGS=$(SHARED_RCFLAG)
23 # LIBNAME contains just the name of the library, without prefix ("lib"
24 # on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so,
25 # .dll, ...). This one MUST have a value when using this makefile to
26 # build shared libraries.
27 # For example, to build libfoo.so, you need to do the following:
31 # APPNAME contains just the name of the application, without suffix (""
32 # on Unix, ".exe" on Windows, ...). This one MUST have a value when using
33 # this makefile to build applications.
34 # For example, to build foo, you need to do the following:
38 # DSTDIR is the directory where the built file should end up in.
41 # SRCDIR is the top directory of the source tree.
44 # OBJECTS contains all the object files to link together into the application.
45 # This must contain at least one object file.
49 # LIBEXTRAS contains extra modules to link together with the library.
50 # For example, if a second library, say libbar.a needs to be linked into
51 # libfoo.so, you need to do the following:
53 # Note that this MUST be used when using the link_o targets, to hold the
54 # names of all object files that go into the target library.
57 # LIBVERSION contains the current version of the library.
58 # For example, to build libfoo.so.1.2, you need to do the following:
62 # LIBCOMPATVERSIONS contains the compatibility versions (a list) of
63 # the library. They MUST be in decreasing order.
64 # For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2
65 # and libfoo.so.1, you need to do the following:
66 #LIBCOMPATVERSIONS=1.2 1
67 # Note that on systems that use sonames, the last number will appear as
69 # It's also possible, for systems that support it (Tru64, for example),
70 # to add extra compatibility info with more precision, by adding a second
71 # list of versions, separated from the first with a semicolon, like this:
72 #LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0
75 # LIBDEPS contains all the flags necessary to cover all necessary
76 # dependencies to other libraries.
79 #------------------------------------------------------------------------------
80 # The rest is private to this makefile.

225 # For Darwin AKA Mac OS/X (dyld)
226 # Originally link_o.darwin produced .so, because it was hard-coded
227 # in dso_dlfcn module. At later point dso_dlfcn switched to .dylib
228 # extension in order to allow for run-time linking with vendor-
229 # supplied shared libraries such as libz, so that link_o.darwin had
230 # to be harmonized with it. This caused minor controversy, because
231 # it was believed that dlopen can't be used to dynamically load
232 # .dylib-s, only so called bundle modules (ones linked with -bundle
233 # flag). The belief seems to be originating from pre-10.4 release,
234 # where dlfcn functionality was emulated by dlcompat add-on. In
235 # 10.4 dlopen was rewritten as native part of dyld and is documented
236 # to be capable of loading both dynamic libraries and bundles. In
237 # order to provide compatibility with pre-10.4 dlopen, modules are
238 # linked with -bundle flag, which makes .dylib extension misleading.
239 # It works, because dlopen is [and always was] extension-agnostic.
240 # Alternative to this heuristic approach is to develop specific
241 # MacOS X dso module relying on whichever "native" dyld interface.
