iOS development overlay for Gentoo

To get started:

1. Download Xcode 4.1 from Apple and place it in /usr/portage/distfiles/.
2. Download this overlay via git, or use a tarball from the Downloads link above: git clone git://github.com/gh2o/ios-overlay.git
3. Add the overlay to your /etc/make.conf: PORTDIR_OVERLAY="/path/to/overlay"
4. Emerge! emerge ios-toolchain

And now let's build something!

grapes.m:

#include <Foundation/Foundation.h>
#include <stdio.h>

int main ()
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];   
    NSLog (@"Go eat some grapes.");
    [pool release];
    return 0;
}

commands:

$ arm-apple-darwin10-gcc grapes.m -o grapes -lobjc -framework Foundation
$ scp grapes mobile@ipod:/tmp/

$ ssh mobile@ipod /tmp/grapes
