Preprocessor include macros don't work

[laszlomonda]

Hi there,

I'd like to use the preprocessor include macros feature of KDS to be able to build different firmware images on a per build profile basis for the various versions of our prototypes. Please see the following screenshot:

For some reason this doesn't work because:

1. The exact same firmware image gets built as without the macro.
2. In source code code editor the PROTOTYPE_VERSION_7 macro section gets grayed out instead of the else clause.

I'd be really grateful if someone could help me.

Thanks in advance!

Hi Erich, and Jennie,

Thank you so much for your help! Erich's instructions totally solved my problem.

Now I have only one question left: What is the preprocessor include macros feature of KDS supposed to do? It seems to me that it doesn't work.

Have a nice day,

Laci

Hi Laci,

In addition,  you can refer this article section2.1 with demo code:

How to support multiple targets in CodeWarrior(Classic, Eclipse)/KDS 

I referred Erich's article when writing this section
https://mcuoneclipse.com/2012/03/20/fixing-the-eclipse-index/

Hope this helps!

Have a great day,
Jennie Zhang

Hi Laci,

add your preprocessor symbols under the -D compiler (C, C++, assembler):

The other thing to know is: Eclipse uses the Indexer data base to gray out the sources. Depending on your project, I recommend you disable heuristics and rebuild the index, see Fixing the Eclipse Index | MCU on Eclipse 

I hope this helps,
