|
-- This package provides a routine for obtaining the version number of the
|
| 35 |
|
|
-- GNAT compiler used to compile the program. It relies on the generated
|
| 36 |
|
|
-- constant in the binder generated package that records this information.
|
| 37 |
|
|
|
| 38 |
|
|
-- Note: to use this package you must first instantiate it, for example:
|
| 39 |
|
|
|
| 40 |
|
|
-- package CVer is new GNAT.Compiler_Version;
|
| 41 |
|
|
|
| 42 |
|
|
-- and then you use the function in the instantiated package (Cver.Version).
|
| 43 |
|
|
-- The reason that this unit is generic is that otherwise the direct attempt
|
| 44 |
|
|
-- to import the necessary variable from the binder file causes trouble when
|
| 45 |
|
|
-- building a shared library, since the symbol is not available.
|
| 46 |
|
|
|
| 47 |
|
|
-- Note: this unit is only useable if the main program is written in Ada.
|
| 48 |
|
|
-- It cannot be used if the main program is written in foreign language.

function Version return String;

-- Here v.vv is the main version number (e.g. 3.16), x is the version
|
| 57 |
|

|

|
|
-- An example of the returned value would be "3.16w (20021029)". The
|
| 59 |
|
|
-- version is actually that of the binder used to bind the program,
|
| 60 |
|
|
-- which will be the same as the compiler version if a consistent
