Variable that is incremented each time the source is compile

The question is there a way to increment a variable in the source each time the source is compiled?

If you are using the CCS IDE then yes there is. I am not sure if this will work with MPLab or the command line tools.

Compiler: 5.026
Device: PIC24EP512GP806

That's actually something I've always wanted to have but never got to the point of asking for it....

I've opened-up Project > Project Options > Global Defines then I have an 'Enabled' checkbox, a Load, Save and Clear button.

So now how does this thing work? How do you add the __BUILDCOUNT__ define in here?

Providing the necessarry steps in order to accomplish this would be greatly appreciated!

Thanks!

First thank you RF_Developer

All I did was to enable the Global Defines in Project Options > Global Defines and save.
Then I put RF_Developer code in my h file close to the top.
Compiled and programed the PIC and looked at variable by output it to the serial port.
Work like a champ.

Guys,

So if there's one for build count, is there one also for the date and time?

Or how would I go about having incremental versions everytime I compile, other than only the buildcount, without having to do it manually?

Otherwise I could always use the buildcount only.

Thanks,

Ben

[EDIT] I enabled global defines in PROJECT->PROJECT OPTIONS and simply hit APPLY. When I compile with an extra printf statement so that I see the buildcount, I get *** Error 12 [filename] Line 302(122,132): Undefined identifier buildcount

Then I went back in the options and just for the kick, I added __BUILDCOUNT__ as an 'identifier' and hit APPLY. This time, it is telling me *** Error 116 [filename] Line 302(120,121): Printf variable count (%) does not match actual count ::

Inside the ccspjt file, it is called <buildcount> rather than __BUILDCOUNT__ so I tried that as well and same problems.

So how to you actually use this?

There are lots of predefined constants and macros for those type of things. Off the top of my head, I want to say __DATE__ and __TIME__, but check the compiler manual. It lists them all. I definitely recommend taking some time and reviewing it. You may find features you need that you didn't know you had available.

Maybe this can be used, from the manual?
...
This pre-processor identifier is replaced at compile time with the time of the compile in the form: "hh:mm:ss"
printf("Software was compiled on ");
printf(__TIME__);
...

There's also one for __DATE__

This is my line:

fprintf( SERIAL_MONITOR, "\n\r[Starting -- build no. %lu on %lu %lu]", __BUILDCOUNT__, __DATE__, __TIME__ );

Ben

[EDIT] Just realized that __DATE__ and __TIME__ are strings. That works. But buildcount still isn't recognized. Is it supported in 5.026?

from the net....somewhere...

5.027 Added __BUILDCOUNT__ id when global defines are enabled

maybe time to contact CCS ??

hehe... well I have compiler 5.069 but for the last week, until I reverted back to 5.026, I had just problems after problems.

Maybe I will re-install and try it again.

Thanks!
