[android-porting] Error customizing AOSP make files for TaintArt -- no rule to make target

[Ayman Youssef]

Hello,

I'm currently building a customized version of AOSP (version 6.0) where I"m
using make files from project TaintArt (
https://github.com/mssun/taintart-art). I copied the make files of the
TaintArt project in the Android directory, they are the same naming
convention of AOSP make files, so they replaced the original AOSP files.
Now when I execute make the following error occurs;

$ make -j16

#### make failed to build some targets (5 seconds) ####

Is it possible to get any help on how I can address this error?

note: I attempted to use "make update-api" but that didn't do any good.

Best Regards,
