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
   7
   8 # CC contains the current compiler.  This one MUST be defined
   9 CC=cc
  10 # LDFLAGS contains flags to be used when the temporary object file is
  11 # created.  SHARED_LDFLAGS contains flags to be used when the shared
  12 # library is created.
  13 LDFLAGS=
  14 SHARED_LDFLAGS=
  15
  16 # LIBNAME contains just the name of thhe library, without prefix ("lib"
  17 # on Unix, "cyg" for certain forms under Cygwin...) or suffix (.a, .so,
  18 # .dll, ...).  This one MUST have a value when using this makefile.
  19 # For example, to build libfoo.so, you need to do the following:
  20 #LIBNAME=foo
  21 LIBNAME=
  22
  23 # LIBEXTRAS contains extra modules to link together with the library.
  24 # For example, if a second library, say libbar.a needs to be linked into
  25 # libfoo.so, you need to do the following:
  26 #LIBEXTRAS=libbar.a
  27 # Note that this MUST be used when using the link_o targets, to hold the
  28 # names of all object files that go into the target library.
  29 LIBEXTRAS=
  30
  31 # LIBVERSION contains the current version of the library.
  32 # For example, to build libfoo.so.1.2, you need to do the following:
  33 #LIBVERSION=1.2
  34 LIBVERSION=
  35
  36 # LIBCOMPATVERSIONS contains the compatibility versions (a list) of
  37 # the library.  They MUST be in decreasing order.
  38 # For example, if libfoo.so.1.2.1 is backward compatible with libfoo.so.1.2
  39 # and libfoo.so.1, you need to do the following:
  40 #LIBCOMPATVERSIONS=1.2 1
  41 # Note that on systems that use sonames, the last number will appear as
  42 # part of it.
  43 # It's also possible, for systems that support it (Tru64, for example),
  44 # to add extra compatibility info with more precision, by adding a second
  45 # list of versions, separated from the first with a semicolon, like this:
  46 #LIBCOMPATVERSIONS=1.2 1;1.2.0 1.1.2 1.1.1 1.1.0 1.0.0
  47 LIBCOMPATVERSIONS=
  48
  49 # LIBDEPS contains all the flags necessary to cover all necessary
  50 # dependencies to other libraries.
