I only found ./prebuilts/clang/linux-x86/host/3.5/lib/libc++.so in Android4.4 platform code and found libc++-shared.so in ndkr10 , do I need use clang to compile llvm-symbolizer code? Here is my Android.mk of llvm-symbolizer in the external/llvm directory, could u tell me how to change this file,plz? Really not familiar with this.
