完全小白，完全按照说明书搭建了ubuntu-12.04.2 64bit开发环境。
解压Android4.1.2源码包，按照说明书的步骤
# . setenv
# make
经过很长时间
最后出现的字样
make: *** [out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/noproguard.classes-with-local.dex] Killed
可能什么地方出错了。
再生成镜像文件
# ./gen-img.sh
说很多文件找不到
cp: target `out/target/product/tiny4412/system/' is not a directory
./gen-img.sh: line 15: out/host/linux-x86/bin/make_ext4fs: No such file or directory
./gen-img.sh: line 23: out/host/linux-x86/bin/make_ext4fs: No such file or directory
./gen-img.sh: line 24: out/host/linux-x86/bin/make_ext4fs: No such file or directory
./gen-img.sh: line 25: out/host/linux-x86/bin/make_ext4fs: No such file or directory
cp: cannot stat `userdata-4g.img': No such file or directory

./gen-img.sh: line 29: out/host/linux-x86/bin/minigzip: No such file or directory
./gen-img.sh: line 30: mkimage: command not found
问题出在哪里，怎么解决？
