How to insert version number into C code AND generated filename

Our project has a standard version numbering system with major, minor and revision numbers. For this discussion, assume they have values 1, 2 and 3 respectively.

I'd like to define the major, minor and revision number components in a single place but with the following twist: the version number components must be accessible to the C compiler (likely defined by the pre-processor) so I can do something like this:

    write_to_flash(make_version_number(VERS_MAJOR, VERS_MINOR, VERS_REVISION));

AND also accessible to KDS/Eclipse, so I can generate an output filename of the form:

    myproj-1-2-3.sbin

I already have a pre-processor script, so I could clearly use it to take build variables and create a .h file from them, so I'd end up with:

    #ifndef SOURCE_VERSION_H
    #define SOURCE_VERSION_H

    #define VERS_MAJOR 1
    #define VERS_MINOR 2
    #define VERS_REVISION 3

    #endif

This way, I only have to define the version numbers (once) in the project's Build Variables. Is this the recommended way to do it? Or is there another preferred technique?

Update: Wait a minute! I thought I'd be able to insert Build Variables into the Debug Configurations dialog in order to control the C/C++ application that it looks for:

... but clearly that's not the case. Let me add a follow-on question: How do I tell the debugger to load the C/C++ application with the filename and version #? Is there a way to expand a Build Variable in the Debug Configurations dialog?

Hello Robert,

Sorry I don't really know your meaning , do you want to rename file with version number ？

If yes, how about the post-build commend:

- Add Build Variable"Newname":

- In Post-build, input command:

- Build , the new name with version number appeares:

Have a great day,
TIC
