建立android系统：缺少system.img

Question

On Mac OS X, after the following steps:

1. $ lunch , and pick full-grouper-userdebug
2. make -j8
3. adb reboot bootloader
4. fastboot flashall -w

I got the error:

error: could not load system.img: No such file or directory

Any idea?

I found the reason that the system.img was missing is the building process failed.

During the building, I got this error:

/bin/bash: line 0: echo: write error: No space left on device

I assigned my /Volumes/android partition a 40GB case-sensitive disk image . While I also put the .ccache under this partition and gave it a space limit of 50GB. Even though I didn't see the size of .ccache grown to very large (maybe around 2GB), I suspect it caused the No space error. So I moved .ccache to another directory other than /Volumes/android , and rebuilt the system. This time, everything goes well, I got the system.img , as shown below.
