It is the bug in tensorflow/contrib/makefile/compile_nsync.sh need to override AR with android’s AR , makefile=’ AR := ${NDK_ROOT}/toolchains/‘“$toolchain”’/prebuilt/‘“$android_os_arch”’/bin/‘“$bin_prefix”’-ar CC=${CC_PREFIX}
${NDK_ROOT}/toolchains/‘“$toolchain”’/prebuilt/‘“$android_os_arch”’/bin/‘“$bin_prefix”’-g++

This is another method I have confirmed. First, just compile it through build_all_android.sh script, then above err msg will print on the terminal. Second, just execute the script “compile_nsync.sh” in the makefile dir, a perfect libnsync.a and nsync.a will be there. Finally, we can link three libs: tensorflowe.a, protobuf.a, libnsync.a. God be with you！

I was basically able to remove the error after removing a particular nsync build folder corresponding to the architecture I was trying to build. For example, I had problem with armeabi and so, I removed ./tensorflow/contrib/makefile/downloads/nsync/builds/armeabi.android.c++11 folder and it built fine after that for that arch

Also, btw, used r14 of NDK.

I am also facing the same issue. Using the instructions on README for Makefile.

Configuration: MacOS Sierra 10.12.6 Android NDK r15c

Any resolution to this?
