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
9 CC=cc
10 CFLAGS=$(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.

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
25 LIBNAME=
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
32 APPNAME=
33
34 # DSTDIR is the directory where the built file should end up in.
35 DSTDIR=.
36
37 # SRCDIR is the top directory of the source tree.
38 SRCDIR=.

40 # OBJECTS contains all the object files to link together into the application.
41 # This must contain at least one object file.
42 #OBJECTS=foo.o
43 OBJECTS=
44
45 # LIBEXTRAS contains extra modules to link together with the library.
46 # For example, if a second library, say libbar.a needs to be linked into
47 # libfoo.so, you need to do the following:
48 #LIBEXTRAS=libbar.a
49 # Note that this MUST be used when using the link_o targets, to hold the
50 # names of all object files that go into the target library.
51 LIBEXTRAS=
52
53 # LIBVERSION contains the current version of the library.
54 # For example, to build libfoo.so.1.2, you need to do the following:
55 #LIBVERSION=1.2
56 LIBVERSION=
57
58 # LIBCOMPATVERSIONS contains the compatibility versions (a list) of
59 # the library.  They MUST be in decreasing order.
60 # For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2
61 # and libfoo.so.1, you need to do the following:
62 #LIBCOMPATVERSIONS=1.2 1
63 # Note that on systems that use sonames, the last number will appear as
64 # part of it.
65 # It's also possible, for systems that support it (Tru64, for example),
66 # to add extra compatibility info with more precision, by adding a second
67 # list of versions, separated from the first with a semicolon, like this:
68 #LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0
69 LIBCOMPATVERSIONS=
70
71 # LIBDEPS contains all the flags necessary to cover all necessary
72 # dependencies to other libraries.

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