| |
| -- 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. |
