You’re using a RPi 2, right? If not then instructions above definitely wouldn’t work.

The 4 lines I gave above are exactly what you need to type to generate the .so file. If trying to use the generated .so is causing a segfault on your RPi 2 then I’m not sure what to suggest.

Yep, Rpi2, even using just make by itself without any of your added code ends up with a seg fault.. also a massive list of errors when trying to make.

It’s hard to tell in your code, but those are “quotes” right.. cause they copy/paste weirdly..
