Problems with compiling the first time

When I am following this guide ( and trying to “make” px4-v2, I get an error:

…/mk/ *** ERROR cannot find the compiler tools for AVR anywhere on the path

What to do?!?!

Thank you

Looks like I got another now…

This is where I’m standing (Look at the image…)


Sorry, I changed the “px-v2” to “px4-v2” and it’s still the same
