I finally was able to compile the Android kernel on OSX, here are the
steps as best I remember them:
1) You need to obtain a copy of elf.h because OSX uses Mach-O format,
not Elf and therefore there is no elf header.
2) Comment out #include <features.h> because it is not needed and not
available as well
3) Install an arm-elf toolchain, I used Macports to do this: sudo port
install arm-elf-gcc
4) make goldfish_defconfig ARCH=arm # Copies
goldfish config to
your .config
5) make ARCH=arm CROSS_COMPILE=arm-elf-
If you want to use 'make menuconfig':
1) Make sure ncurses library is installed (Can be done through Macports)
1) Comment out the "exit 1" in scripts/kconfig/lxdialog/check-
lxdialog.sh so the ncurses check does not fail
Build Errors:
* If you get something about an error with i686 or x68, you probably
forgot ARCH=arm
* If you get the error NOT AN ELF FILE, then you are probably using
the Apple GCC compile which outputs MACH-O
files, and you should be using a ARM-ELF cross compiler instead.
* Another potential problem is if you are not using a GCC compiler
