Thanks for your reply.

Compiler-rt was a problem. From the documentation I thought it was 
mandatory (so what is it used for?),

but it was giving all those error about stdbool.h missing that I reported.

Now things got better, but I have still problems.

I receive an error that seems related to the fact that the grep command 
is missing.

Is it possible? If grep is needed, how can I found it in Windows?

Thanks in advance,
