[Icc-mot] Build/Link time

[Barry Callahan]

I want to keep a string that indicates the date and time that the 
firmware was built.

Right now, I'm building a string with __DATE__ and __TIME__

Problem is, those are evaluated by the preprocessor at compile time. If 
I modify a file which doesn't reference those macros and forget to do a 
"rebuild all", the version string doesn't get updated.

In ICC12 (both v6 and v7) there's a text field under the "Compiler" tab 
of the "Compiler Options" dialog labeled "Execute Command After 
Successful Build:"

Right now, I'm using this field to touch (update the modification time) 
on the file which builds the timestamp. That way, (assuming the build 
completed successfully) the next time I rebuild, that file will be 
guaranteed to recompile, regardless of whether I edit it or not.

Ideally, I'd touch this file *before* building so I know that the string 
always accurately reflects the date and time of when the program was 
built, regardless of whether the previous compile was clean or not..


Any suggestions?
Thanks.
