    • Detecting active build config at compile time

    Posted by mikelj99 on 2018-08-06 10:25

    Newbie on the site using NUCLEO-F767ZI - forgive me any unintended indiscretions, but do point them out so I can learn.

    How do I detect which build config is active at time of compilation?

    If DEBUG is active then I want to printf info to the console
    otherwise send the same info via UART

    Code example ...

    1. ifdef DEBUGactive

    printf(...);

    1. else

    send(...);

    1. endif

    Hi,

    You're almost right in your guess: use #ifdef DEBUG and it will work 😎

    hi

    ich have one projekt with 3 different targets

    so i configured 3 different build configurations.

    "TEST_A" : symbols: TEST_A
    "TEST_B" : symbols: TEST_B ; FEATURE_B
    "TEST_C" : symbols: TEST_B ; FEATURE_C

    BUT:
    In my sources i use preprocessor switches ( #ifdef / #endif ) to select the functions.

    but i cant see any changes in highlighting in sources.
    it seems it compiles correctly ... but you can't see the changes if you switch the active build configuration.

    is there a "trick" ?


    EDIT:

    i can use i any headerfile #define TEST_A ...
    but i think this is also possible with different configurations like "Debug/Release"
