Doesn't find any board configuration

[narrowtux]

I have a very simple project configuration, posted on this Gist.

As you can see, I reconfigured the example config a bit but everything else is still at the same place (toolchain and Arduino.cmake files in cmake/...).

When I execute cmake from the build/ directory with cmake .., it will throw this error:

Scarecrow:build tux$ cmake ..
--

CMake Error at cmake/Platform/Arduino.cmake:830 (message):

-- Configuring incomplete, errors occurred!

See also "/Users/tux/Downloads/arduino-cmake-master/build/CMakeFiles/CMakeError.log".

As you can see, it can't find the configuration for the Arduino Uno. In fact, it doesn't have any configuration for any other board (since you can see print_board_list() doesn't list anything.

I dug a bit with cmake --trace .. and saw that register_hardware_platform(${ARDUINO_SDK_PATH}/hardware/arduino/) is never executed.

Can I change something in my configuration so it will load the boards.txt file?

This happens because the master branch is currently not compatible with the Arduino SDK 1.5/1.6.

I had more luck with: https://github.com/blemasle/arduino-cmake But you need to set ARDUINO_1_5 to True.

Honestly, Ardunio development is a huge mess right now ... It all needs to settle down a bit.

Thanks, that worked :)

For the sake of people still having a problem with this, I have found that changing set(${PROJECT_NAME}_BOARD pro) to set(${PROJECT_NAME}_BOARD uno) or any other board fails unless I comment out set(ARDUINO_CPU 16MHzatmega328). It appears that setting the CPU causes problems if the board doesn't support multiple CPUs

I think the issue is caused by the folder structure of the arduino sdk. The boards.txt is located in your_path_to_sdk/hardware/arduino/avr. However, in the CMakeLists.txt, the path where the boards.txt file is required to be is: your_path_to_sdk/hardware/arduino. Changing this worked for me. I am using arduino sdk 1.8.6.

The issue mentioned by @axelbr can be solved by adding register_hardware_platform(${ARDUINO_SDK_PATH}/hardware/arduino/avr) to your CMakeLists.txt (so you shouldn't even patch arduino-cmake itself). I know it's an old thread, but I found this page by googling the error message, so I wanted to share this solution for other people landing here.

Thank you @maartendemunck. That worked for me.

I came across this issue looking for a solution with the Clion arduino plugin on arch linux. The solution here was to create a soft link for the arduino hardware platform path which is usually /usr/share/arduino/hardware/archlinux-arduino/avr and should be /usr/share/arduino/hardware/arduino/avr. It was also necessary to recreate the Clion arduino project. With an existing project which I imported from my old linux environment it didn't worked due to register_hardware_platform(${ARDUINO_SDK_PATH}/hardware/arduino/avr) was never called. Im currently not sure why it works with a new created Clion arduino project but anyway it works :smile:

Thanks @schlegel11. I had to recreate the project as well after ln -s /usr/share/arduino/hardware/archlinux-arduino/ /usr/share/arduino/hardware/arduino
