There are several packages providing -- the actual routines. This package calls them indirectly by means of -- access-to-subprogram values. Each target-dependent package initializes -- these values in its elaboration block. with Prj; use Prj; package MLib.Tgt is function Support_For_Libraries return Library_Support; -- Indicates how building libraries by gnatmake is supported by the GNAT -- implementation for the platform. function Standalone_Library_Auto_Init_Is_Supported return Boolean; -- Indicates if when building a dynamic Standalone Library, -- automatic initialization is supported. If it is, then it is the default, -- unless attribute Library_Auto_Init has the value "false". function Archive_Builder return String; -- Returns the name of the archive builder program, usually "ar" function Archive_Builder_Options return String_List_Access; -- A list of options to invoke the Archive_Builder, usually "cr" for "ar" function Archive_Builder_Append_Options return String_List_Access; -- A list of options to use with the archive builder to append object -- files ("q", for example). function Archive_Indexer return String; -- Returns the name of the program, if any, that generates an index to the -- contents of an archive, usually "ranlib". If there is no archive indexer -- to be used, returns an empty string. function Archive_Indexer_Options return String_List_Access; -- A list of options to invoke the Archive_Indexer, usually empty function Dynamic_Option return String; -- gcc option to create a dynamic library. -- For Unix, returns "-shared", for Windows returns "-mdll". function Libgnat return String; -- System dependent static GNAT library function Archive_Ext return String; -- System dependent static library extension, without leading dot. -- For Unix and Windows, return "a". function Object_Ext return String; -- System dependent object extension, without leading dot. -- On Unix, returns "o". function DLL_Prefix return String; -- System dependent dynamic library prefix. -- On Windows, returns "". On other platforms, returns "lib". function DLL_Ext return String; -- System dependent dynamic library extension, without leading dot. -- On Windows, returns "dll". On Unix, usually returns "so", but not -- always, e.g. on HP-UX the extension for shared libraries is "sl". function PIC_Option return String; -- Position independent code option function Is_Object_Ext (Ext : String) return Boolean; -- Returns True iff Ext is an object file extension function Is_C_Ext (Ext : String) return Boolean; -- Returns True iff Ext is a C file extension function Is_Archive_Ext (Ext : String) return Boolean; -- Returns True iff Ext is an extension for a library function Default_Symbol_File_Name return String; -- Returns the name of the symbol file when Library_Symbol_File is not -- specified.
