Problems with compiling the first time

Hello!
When I am following this guide (dev.ardupilot.com/wiki/building-px4-with-make/) and trying to “make” px4-v2, I get an error:

…/mk/find_tools.mk:67: *** 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…)

Thanks!

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