------------------------------------------------------------------------------
-- This package provides a routine for obtaining the version number of the
-- GNAT compiler used to compile the program. It relies on the generated
-- constant in the binder generated package that records this information.
-- Note: to use this package you must first instantiate it, for example:
-- package CVer is new GNAT.Compiler_Version;
-- and then you use the function in the instantiated package (Cver.Version).
-- The reason that this unit is generic is that otherwise the direct attempt
-- to import the necessary variable from the binder file causes trouble when
-- building a shared library, since the symbol is not available.
-- Note: this unit is only useable if the main program is written in Ada.
-- It cannot be used if the main program is written in foreign language.
generic
package GNAT.Compiler_Version is
pragma Pure;
function Version return String;
-- This function returns the version in the form "v.vvx (yyyyddmm)".
-- Here v.vv is the main version number (e.g. 3.16), x is the version
-- designator (e.g. a1 in 3.16a1), and yyyyddmm is the date in ISO form.
-- An example of the returned value would be "3.16w (20021029)". The
-- version is actually that of the binder used to bind the program,
-- which will be the same as the compiler version if a consistent
-- set of tools is used to build the program.
end GNAT.Compiler_Version;
