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)

Try using this as an reference: github.com/.../main.cpp In it they use # ifdef __IS_COMPILER_GCC__ ----- Also Arm Compiler 6 is based off Clang, and clang defines the GCC flag. See: ...

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
-D__EVAL -gdwarf-3 -O1 -ffunction-sections -Weverything -Wno-packed -Wno-reserved-id-macro -Wno-unused-macros -Wno-documentation-unknown-command -Wno-documentation -Wno-license-management -Wno-parentheses-equality 
-I./RTE/Device/STM32F103C8
-I./RTE/_Target_1

My screen shows (I expected GCC not to be defined for a Keil compiler):

Suggestions on how I can conditionally compile for Keil versus GCC?
