Makefile.shared

   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

   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 # 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
  37 OBJECTS=
  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.
  45 LIBEXTRAS=
  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
  50 LIBVERSION=
  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
  63 LIBCOMPATVERSIONS=
  64
  65 # LIBDEPS contains all the flags necessary to cover all necessary
  66 # dependencies to other libraries.

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