| 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. | |
| 47 | |
| 48 generic | |
| 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. | |
