Hello!

In "CMakeCache_Working.txt" I see 

//Path to a program.
CMAKE_ADDR2LINE:FILEPATH=/home/m.wolz/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-addr2line

//Path to a program.
CMAKE_AR:FILEPATH=/home/m.wolz/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-ar

In "CMakeCache.txt" I see

//Path to a program.
CMAKE_ADDR2LINE:FILEPATH=/usr/bin/addr2line

//Path to a program.
CMAKE_AR:FILEPATH=/usr/bin/ar

Could you please explain the situation one more time and in more detail? Why do you have two CLion instance running? Are both instances running on the same machines? Do you have the same toolchain settings in these instances? Do you open the same project in them?

Hi Anna,

we have a few STM devices in our projects. For the two controller I'm working with, I have two windows of CLion (one for MC controller the other for EC controller) running.
For debugging purpose I have one window for the called MC controller and one for the EC controller.

For each controller we have a separate cmake file.
Mc controller is working fine.
For the EC controller I get the mentioned error message.

The Toolchain is the same for both controller
Cmake: bundled Version 3.17.3
make: 7user/bin/make
C compiler /home/m.wolz/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-gcc
C++ compiler /home/m.wolz/gcc-arm-none-eabi-7-2018-q2-update/bin/arm-none-eabi-g++
Debugger: bundled GDB Version9.2

Only difference is, that I path different CMAKE options depending on the controller.
Both are included in the same project
projects root elisa2/app/BC controller
                                      CC controller
                                      EC controller
                                      MC controller
                                      ....

PATH variables for both controller PATH /home/m.wolz/gcc-arm-none-eabi-7-2018-q2-update/bin:/usr/bin:

hope this help.
I reset the cmake cache of the EC controller a few times, without any change.
Is there a possbility to set the cmake_addr2Line of the window for the EC controller manuall to the correct FILEPATH?
regards Matthias

Please try adding the following lines before the project() command in your CMakeLists.txt:

SET(CMAKE_SYSTEM_NAME Generic)
SET(CMAKE_SYSTEM_VERSION 1)

Hi Anna,

sorry for my late response, but I was on parental leave.

I tried your suggestion, but it didn't solve it.

Hi Anna,

adding

SET(CMAKE_SYSTEM_NAME Generic)
SET(CMAKE_SYSTEM_VERSION 1)
SET(CMAKE_C_COMPILER_WORKS 1)
SET(CMAKE_CXX_COMPILER_WORKS 1)

solved the problem. Thanks

I'm glad it helped!

I know this is an old post but it looks like adding the following before the project line works as well

set(CMAKE_TRY_COMPILE_TARGET_TYPE STATIC_LIBRARY)
