Neon support not enabled on building 64bit android

I want my android game built with 64 bit support because of google 64 bit policy.

I compiled 1.7.1 with URHO3D_64BIT=1. But, I always getting this error.
“NEON support not enabled”

Am I missing something?

Thanks

I recommend you switch to Gradle build system with master branch. Having said that, I think Android arm64 build was ok with 1.7 too. Check the online doc for version 1.7 for the correct build option to use.

Finally, figure it out.
I tried to change ANDROID_ABI=arm64-v8a , but got error

Unrecognized ‘arm64-v8a’ specified in the ANDROID_ABI option, supported values are: “armeabi-v7a”, “armeabi-v6”, "armeabi

Looked at android doc, changed ANDROID_TOOLCHAIN_NAME=aarch64-linux-android-clang and ANDROID_NATIVE_API_LEVEL=android-21 (minimum version).
Compiled successfully.
