I've scanned over the (outdated) article that is the first hit on google about ARM cross-compiling. I've also seen the article about compiling OpenCV to the iPhone and the general cross compiling instructions there. My question is can I call the apparently already configured gcc/g++ in the iPhone developer package (which I already have installed) like in the latter article? A lot of the OpenCV stuff seems superfluous to my needs.
If I can, what would the calls look like? Should I create a Makefile to make things easier?
Also, I need -lncurses library. Can I call them like normal, or do I need to specify it's path because I'm not calling the default gcc/g++?

GCC, a free software collection of compilers, can be set up to cross compile. It supports many platforms and languages. Cross-compiling GCC requires that a portion of the target platform's C standard library be available on the host platform.
"building a cross-compiler is significantly harder than building a compiler that targets the platform it runs on." The problem exists due to the way libraries are built and accessed. In the normal situation all the libraries are located in a specific spot, and are used by all apps on that system.
If you're using the official SDK, compiling C++ for the iPhone is as simple as including cpp files in your project and hitting "build". Of course you can still go in and tweak the compiler switches - well, most of them.
As for ncurses, I'm not sure why you'd want to use that - but the only limitation you should have is that you can't link against dynamic libraries - so you'd have to linked the object code in.
