32 -- This package provides a routine for obtaining the version number of the
33 -- GNAT compiler used to compile the program. It relies on the generated
34 -- constant in the binder generated package that records this information.
35
36 -- Note: to use this package you must first instantiate it, for example:
37
38 -- package CVer is new GNAT.Compiler_Version;
39
40 -- and then you use the function in the instantiated package (Cver.Version).
41 -- The reason that this unit is generic is that otherwise the direct attempt
42 -- to import the necessary variable from the binder file causes trouble when
43 -- building a shared library, since the symbol is not available.
44
45 -- Note: this unit is only useable if the main program is written in Ada.
46 -- It cannot be used if the main program is written in foreign language.

49 package GNAT.Compiler_Version is
50 pragma Pure;
51
52 function Version return String;
53 -- This function returns the version in the form "v.vvx (yyyyddmm)".
54 -- Here v.vv is the main version number (e.g. 3.16), x is the version
55 -- designator (e.g. a1 in 3.16a1), and yyyyddmm is the date in ISO form.
56 -- An example of the returned value would be "3.16w (20021029)". The
57 -- version is actually that of the binder used to bind the program,
58 -- which will be the same as the compiler version if a consistent
59 -- set of tools is used to build the program.
