> armv6-vfp-linux-gnueabi-gcc hi.c -o hi -static

> Note the -static. I've not figured out the version of libc etc or the
> ABI used yet, so for now, link applications statically.

> 3) Copy to a running emulator:
> adb push hi /system/sbin/hi

> 4) Run it! From the emulator console:
> cd /system/sbin
> ./hi

> 5) Smile as you see "hello world" printed on the console. :-)
