1) Are you sure you have latest tools and libraries? Please do pacman -Syu to ensure you're upgraded.
2) You're missing console init/deinit code, and other scaffolding code. Please take a look at the template source code to see what a typical console homebrew application should look like.
3) iostreams are a really questionable part of the C++ standard library that adds a lot of code size bloat and code verboseness for little, if not dubious benefit. It is usually recommended by us to stick to standard printf.
