If problems with PlatformIO Build System:

The content of platformio.ini:

check_tool = clangtidy

Additional info

According to the internet, the include paths can be shorted to be an environmental variable. Therefore, a fix would include using variable substitution for the top common prefix (Or just %HOME%, since everything is coming from the home directory) resulting in a massive reduction in the generated GCC command.

I have no solution, but at least I have the same problem :)
Could someone look into this?

[zackees]

Honestly at this point, someone is going to have to volunteer to fix it and submit a PR.

I have the same question, but I can't figure out the solution

@tao4091 , could you share your platformio.ini?
