27 # .dll, ...).  This one MUST have a value when using this makefile to
28 # build shared libraries.

31 LIBNAME=
32
33 # STLIBNAME contains the path of the static library to build the shared

46 # build, for example:
47 #SHLIBNAME_FULL=libfoo.so.1.2
48 # When building DSOs, SHLIBNAME_FULL contains path of the full DSO name, for

50 #SHLIBNAME_FULL=dir/dso.so

60 # cases, SHLIBVERSION as well.  To build DSOs, SHLIBNAME_FULL MUST have

65 # on Unix, ".exe" on Windows, ...).  This one MUST have a value when using

68 #APPNAME=foo

70
71 # SRCDIR is the top directory of the source tree.

76 #OBJECTS=foo.o
77 OBJECTS=
78

80 # For example, if a second library, say libbar.a needs to be linked into
81 # libfoo.so, you need to do the following:
82 #LIBEXTRAS=libbar.a
83 # Note that this MUST be used when using the link_dso targets, to hold the
84 # names of all object files that go into the target shared object.

207 # For Darwin AKA Mac OS/X (dyld)
208 # Originally link_dso.darwin produced .so, because it was hard-coded
209 # in dso_dlfcn module. At later point dso_dlfcn switched to .dylib
210 # extension in order to allow for run-time linking with vendor-
211 # supplied shared libraries such as libz, so that link_dso.darwin had
212 # to be harmonized with it. This caused minor controversy, because
213 # it was believed that dlopen can't be used to dynamically load
214 # .dylib-s, only so called bundle modules (ones linked with -bundle
215 # flag). The belief seems to be originating from pre-10.4 release,
216 # where dlfcn functionality was emulated by dlcompat add-on. In
217 # 10.4 dlopen was rewritten as native part of dyld and is documented
218 # to be capable of loading both dynamic libraries and bundles. In
219 # order to provide compatibility with pre-10.4 dlopen, modules are
220 # linked with -bundle flag, which makes .dylib extension misleading.
221 # It works, because dlopen is [and always was] extension-agnostic.
222 # Alternative to this heuristic approach is to develop specific
223 # MacOS X dso module relying on whichever "native" dyld interface.
