I download gcc compiler but could not find the program. I can build default arduplane code but i cannot build our code. pls help me. thanks for your answer.

You’ve not installed the GCC ARM compiler. See Setting up the waf Build Environment on Windows using Cygwin — Dev documentation

I’m sure i installed gcc. Does it matter where i install it ?

i restarted my pc and i got it. thanks for advice
