Hi Jerry -- I can't help with diagnosing your error messages, but I'm wondering whether you ever did a RPi operating system update? If not, do one and retry your commands.

Message:    I have a raspberry pi 3. I did all the instructions for the WSPR PI GPIO4

I get warnings on the make, but it still builds anyway.

When I do the following command:
sudo ./wspr -r -o -s K7AZJ DM33XI 20 20m

My pi IMMEDIATELY crashes. I have a friend that has a rpi 3, and it doesn't crash.

I do not have my antenna or wspr pi board hooked up.

Here is the warnings on the make:
