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_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 leadien 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 procedure Build_Dynamic_Library (Ofiles : Argument_List; Foreign : Argument_List; Afiles : Argument_List; Options : Argument_List; Options_2 : Argument_List; Interfaces : Argument_List; Lib_Filename : String; Lib_Dir : String; Symbol_Data : Symbol_Record; Driver_Name : Name_Id := No_Name; Lib_Version : String := ""; Auto_Init : Boolean := False); -- Build a dynamic/relocatable library -- -- Ofiles is the list of all object files in the library -- -- Foreign is the list of non Ada object files (also included in Ofiles) -- -- Afiles is the list of ALI files for the Ada object files -- -- Options and Options_2 are lists of options to be passed to the tool -- (gcc or other) that effectively builds the dynamic library. Options -- are passed before the object files, Options_2 are passed after the -- object files. -- -- Interfaces is the list of ALI files for the interfaces of a SAL. -- It is empty if the library is not a SAL. -- -- Lib_Filename is the name of the library, without any prefix or -- extension. For example, on Unix, if Lib_Filename is "toto", the -- name of the library file will be "libtoto.so". -- -- Lib_Dir is the directory path where the library will be located -- -- For OSes that support symbolic links, Lib_Version, if non null, -- is the actual file name of the library. For example on Unix, if -- Lib_Filename is "toto" and Lib_Version is "libtoto.so.2.1", -- "libtoto.so" will be a symbolic link to "libtoto.so.2.1" which -- will be the actual library file. -- -- Symbol_Data is used for some patforms, including VMS, to generate -- the symbols to be exported by the library. -- -- Note: Depending on the OS, some of the parameters may not be taken -- into account.
