Is there a known issue with latest Qt Creator? I have done all the steps many times, before and successfully built/ran the code on Arduino. Now project just does not build and fails with this error:
11:23:15: Running steps for project platformio…
11:23:15: Cannot find Makefile. Check your build settings.
Error while building/deploying project platformio (kit: Desktop Qt 5.9.1 GCC 64bit)
When executing step "Make"
11:23:15: Elapsed time: 00:00.
I use standart settings as before. It does build and upload just fine from the terminal.
