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 # 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.
67 LIBDEPS=
