CLion integration not working (include error)

[jenswet]

Hello,

I tried to create a new CLion project and copied the 0.6 release at my project.

This is my CMakeLists.txt:

cmake_minimum_required(VERSION 3.12)
set(CMAKE_TOOLCHAIN_FILE ${CMAKE_SOURCE_DIR}/cmake/Arduino-Toolchain.cmake)
project(Arduino LANGUAGES C)

get_board_id(board_id mega atmega2560)
add_arduino_executable(${PROJECT_NAME} ${board_id} main.c)
upload_arduino_target(${PROJECT_NAME} "${board_id}" COM3)

My folder structure is: Arduino (CLion project root)

• cmake (contains the whole 0.6 release)
• CMakeLists.txt
• main.c

Unfortunately I get this error.

I couldn't find any solution on github. I already tried a cmake command line parameter instead of the set(CMAKE_TOOLCHAIN_FILE ${CMAKE_SOURCE_DIR}/cmake/Arduino-Toolchain.cmake). This didn't help. I also tried different relative and absolute paths without success.

Can anyone help me?

Thank you :)

@jenswet Hello there, I'm sorry for being late and answering only now, I'm currently on an extremely busy schedule. It's a strange issue you got there since I'm developing in CLion myself, as well as many others involved in this project and it works just fine for us.

I'd start with replacing the set(CMAKE_TOOLCHAIN_FILE ${CMAKE_SOURCE_DIR}/cmake/Arduino-Toolchain.cmake) line with a command-line variable (which you can set in Settings->CMake). I know you already tried that, but my guess is that something wasn't configured right: It's probably worth mentioning that you should pass an absolute path to the command variable, otherwise it won't work! At last, remember to reset cache after the change and not just reload it!

Please let me know if that solved your problem, and attach the output if it's not.

Hello @MrPointer, thanks for your answer.

Unfortunately I still can't get it to work:

My new CMakeLists.txt:

cmake_minimum_required(VERSION 3.8.2)
project(Arduino)

get_board_id(board_id mega atmega2560)
add_arduino_executable(${PROJECT_NAME} ${board_id} main.c)
upload_arduino_target(${PROJECT_NAME} "${board_id}" COM3)

Obviously it still doesn't like my installation.

Which operating system are you using? I'm on macOs 10.13.6.

[MrPointer]

@jenswet May I ask if this path /Users/jens/Downloads/Arduino is the path to your CMakeLists.txt file?

As to your question - I'm using Windows 10 but it doesn't really matter as it seems it doesn't work for you at all, not even when using the command-line, which is really strange since we've got this covered in our CI builds - We build for OS X, Linux and Windows.

[jenswet]

Yes this is the absolute path to CmakeLists. Can I provide any Information for debugging?

[MrPointer]

Did you install the project and all of its dependencies just as listed in the installation notes?

[jenswet]

I used the CLion CMake bundled before. Now I installed CMake as additional dependency and configured it as Toolchain but it does not change the situation. Arduino IDE is installed as usual.

[MrPointer]

@jenswet I know I'm extremely late, but is it still relevant?

If so, could you please attach the output of your project's directory listing? I mean to execute ls -lR from the terminal.
