Yes, stdio.h is part of libc not libcxx and should exist in the sysroot 
*for the platform you're compiling for*.

It's likely that the compiler is configured to compile for your dev 
machine by default.

I don't know what those restrictions are, but you should probably tell 
your compiler where it should find the sysroot for the platform you wish 
to compile for.

That's probably not a great idea, the libc for your dev machine and the 
one on your ios device might differ.

I'm lost.

Good luck.
