Crypto++ build aborted suddenly

[Ninad Deshmukh]

Hi All

I build Crypto++ last week and doing some wrapper changes..

But today when I am trying to build again it gives following error.
Looks like some ABDs are deprecated, but I wonder why suddenly I am not able to compile?

'grep' is not recognized as an internal or external command,

operable program or batch file.

C:/Microsoft/AndroidNDK64/android-ndk-r16b/build//../build/core/setup-app.mk:81: Android NDK: Application targets deprecated ABI(s): mips64 armeabi mips

C:/Microsoft/AndroidNDK64/android-ndk-r16b/build//../build/core/setup-app.mk:82: Android NDK: Support for these ABIs will be removed in a future NDK release.

process_begin: CreateProcess(NULL, bash make_neon.sh, ...) failed.

Android NDK: NEON support is only available for armeabi-v7a  arm64-v8a  x86  and x86_64 ABIs

Android NDK: Please add checks against TARGET_ARCH_ABI in Android.mk

C:/Microsoft/AndroidNDK64/android-ndk-r16b/build//../build/core/build-binary.mk:329: *** Android NDK: Aborting    .  Stop.

Any guesses What do I need to correct?

which Android.mk error is talking about..

r16 is kind of old. Android no longer supports MIPS targets. You
should probably upgrade to a newer version of the NDK.

The various Android build files (like senenv-android.sh and
Android.mk) work with r17 and above, if I recall. r17 is needed
because the Android folks changed the directory layout at r17 (yet
again), so we had to change our scripts to match the new layout.

Also see https://www.cryptopp.com/wiki/Category:Android on the
Crypto++ wiki. The wiki pages are our documentation for the build
files. https://www.cryptopp.com/wiki/Android_Setup_(Command_Line)
shows how we setup our test machines.
