@Theodore-Borromeo That's what I thought, but it's not the case. Using -rpath options together with their libonionspi.so did nothing. I'm not sure what's going on.

Anyway, I was doing this for fun, and to prove a point. It is possible to compile and link on the Onion Omega using gcc. If you have the diskspace, since gcc is about 22MB.

Cloud compiling is coming soon. No need for this stuff. :)
