Android Source Code Build Error for snapdargon8074

Im trying to build Android5.0 source code from code-aurora for snap dragon 8074. Encountered the following error:

target SharedLib: libandroid_runtime (out/target/product/msm8974  /obj/SHARED_LIBRARIES/libandroid_runtime_intermediates/LINKED/libandroid_runtime.so)
frameworks/base/core/jni/android/graphics/Paint.cpp:809: error: undefined reference to 'android::uirenderer::Blur::convertRadiusToSigma(float)'
collect2: error: ld returned 1 exit status
make: *** [out/target/product/msm8974/obj/SHARED_LIBRARIES/libandroid_runtime_intermediates/LINKED/libandroid_runtime.so] Error 1

#### make failed to build some targets (06:19:52 (hh:mm:ss)) ####

And i had downloaded the source code mentioned for the snapdragon8074. I ran following commands to build

$ source build/envsetup.sh
$ lunch msm8974-userdebug
$ make

Please help me solve this issue.

Thanks in Advance.
