I tried to create an Android operating system for the Galaxy Nexus. It took 6 hours. Is this normal or is it related to my machine (MBP Core2Duo) or am I missing something?
This is a bit of memory bound operation. The next time you compile try, use more threads
make -j8
or
make -j16
With 12 GB of memory, I was able to compile the source for Android in 40 minutes.
