I don't know, I've never done a cross-compile before.

You would compile your app, then move the binary over to the target
platform.  If the target platform has libc and a dynamic linker, you
won't have to build it yourself and link statically (I expect).

I expect, too, that you'll need the header files from the libc on the
target platform to get any compiler checks to work right.  Probably
also necessary to get struct sizes and member alignment.

This is not C.  You also forgot to #include<iostream>.

Do they have libstdc++ on those platforms?
