[General Questions and Answers] :
I tried to compile CyanogenMod 11 for my device [Coolpad 8085 (lc1810_8190)].

There is a problem when I run this command.

. build/tools/device/makerecoveries.sh cm_lc1810_8190-eng

cm_lc1810_8190-eng
1 Products
Recovery Version: 6.0.4.8
Trying dependencies-only mode on a non-existing device tree?

build error!

At first I guess if something was lost, then I download bionic/libc/private, but the problem doesn't gone.

I want to build a Cyanogenmod 11 for my device because the offical rom is too ugly and too old.

Thanks a lot.
