Is __CC_ARM not defined in the MDK Eval Version?

I'm working on a simple project and trying to make it work for both STM32CubeIDE and Keil uVision.  Building in uVision, in *my* files __CC_ARM is not defined. If I manually define it on the Target1 Options C Compiler form, then I get a million errors says that it is already defined in *other* files. Other files meaning supplied things like

stm32f10x.h(483): warning: In file included from...

I can see that in "core_cm3.h" it is already defined (magically).

Ideas??

I noticed someone doing this:

#if defined(__CC_ARM) || defined(__ARMCC_VERSION)

  • Hi,

    I'm still confused gang.I'm still getting what looks to me like GCC and not Keil? My objective is to be able to conditionally compile slightly different code for each, as needed. So,

    I created a new project from scratch using C:\Keil_v5_MDK\UV4\UV4.exe  (File Version 5.34.0.0)

    I see, under default Target1 -> Options

    Arm Compiler: Use default compiler version 6

    The Compiler control string is:

    -xc -std=c99 --target=arm-arm-none-eabi -mcpu=cortex-m3 -c
    -fno-rtti -funsigned-char -fshort-enums -fshort-wchar
