Build number?

mattgeerts — Fri, 24 Jul 2015 13:14:19 GMT

How can I auto-generate a build number at compile time? I want to use this number to report firmware version via uart or display.

Also, how can I have my build automatically name the output file with the build number, or any other macro?

So far I'm using __DATE__ and __TIME__. However, I hate this because the date is not ISO standard! I also don't know how to get this into the file name automagically.

Thanks!

Hi Matt,

I have a static method to do this but hopefully someone else has dynamic version too.

In the Properties you can do a Define symbol in the Preprocessor as shown below:

In your "C" file do the following for declaration:

static const unsigned int BUILD_NUMBER = __BUILD_NUMBER;

//DES added as a Pre-Processor Define constant

Then in code you can printf it.

PRINTF("\r\nBUILD_NUMBER = 0x%X", BUILD_NUMBER);

//DES added

I used the hello_world_frdmk64f as my test project in KSDK_1.2..

My terminal output looked like:

Hello World!

BUILD_NUMBER = 0x12345670

David

Thanks David,

The goal is really to do this in a way that doesn't require manually updating the number.

For years in Metroworks Codewarrior I would just keep a version.c in my project that contained either strings or chars to define the current project release, but i've never tracked per-build.

Can we have KDS run a batch file on compile or something? Then I could just have a batch file read a C file with a number in it, then delete the number and incriment a new number in its place. Dirty, but it would work.

Hi Matt,

You can use the Build Steps properties tab to customize the selected build configuration, in this case you can call a batch file immediately after building.

Go to menu Project > Properties > C/C++ Build > Settings > Build Steps.

Hope it helps.
