Looks like I need to use SEGGER_RTT_Syscalls_GCC.c.

Hi Stian,

Thanks for your response.

Now C and C++ compilers are identified.

But getting below error

segger_rtt/SEGGER_RTT_Syscalls_SES.c:75:10: fatal error: __libc.h: No such file or directory

When I looked into Segger installation folder

C:\Program Files\SEGGER\SEGGER Embedded Studio for ARM 4.10\include

we can find __libc.h file

but in the ARM tool chain installation which I am using doesn't have __libc.h file

C:\Program Files (x86)\GNU Tools Arm Embedded\9 2019-q4-major\arm-none-eabi\include.

Please advice how to fix this.

Hi, in addition to the previous CMakeLists.txt, I'm including the following file to setup the toolchain:

endif()

Not sure if everything is needed, but at least make sure that the arm-none-eabi include directories are included, similar to the last 5 lines above

I have installed arm-none-eabi on my laptop which is running on Windows 10 OS and below variable definitions I have added in Environment variables.

ARM_NONE_EABI_TOOLCHAIN_PATH = C:\Program Files (x86)\GNU Tools Arm Embedded\9 2019-q4-major

CC = C:\Program Files (x86)\GNU Tools Arm Embedded\9 2019-q4-major\bin\arm-none-eabi-gcc.

I am getting the below error

Here is my modified CMakeLists.txt file
