27 -- This package provides a set of target dependent routines to build
28 -- static, dynamic and shared libraries.
30 -- There are several versions for the body of this package
32 -- In the default version, libraries are not supported, so function
33 -- Support_For_Libraries return None.
39 type Library_Support is (None, Static_Only, Full);
40 -- Support for Library Project File.
41 -- - None: Library Project Files are not supported at all
42 -- - Static_Only: Library Project Files are only supported for static
44 -- - Full: Library Project Files are supported for static and dynamic
45 -- (shared) libraries.

53 -- automatic initialization is supported. If it is, then it is the default,

64 -- files ("q", for example).
66 function Archive_Indexer return String;
67 -- Returns the name of the program, if any, that generates an index to the
68 -- contents of an archive, usually "ranlib". If there is no archive indexer
69 -- to be used, returns an empty string.
71 function Archive_Indexer_Options return String_List_Access;
72 -- A list of options to invoke the Archive_Indexer, usually empty

144 -- extension. For example, on Unix, if Lib_Filename is "toto", the

147 -- Lib_Dir is the directory path where the library will be located
149 -- For OSes that support symbolic links, Lib_Version, if non null,
150 -- is the actual file name of the library. For example on Unix, if
151 -- Lib_Filename is "toto" and Lib_Version is "libtoto.so.2.1",
152 -- "libtoto.so" will be a symbolic link to "libtoto.so.2.1" which
153 -- will be the actual library file.

156 -- the symbols to be exported by the library.
