Android.mk

## Android.mk - Android build file for Crypto++.
##
## Written and placed in public domain by Jeffrey Walton. This
## Android.mk is based on Alex Afanasyev (GitHub @cawka) PR #3,
## https://github.com/weidai11/cryptopp/pull/3.
##
## The Android build system is a wrapper around GNU Make and is
## documented https://developer.android.com/ndk/guides/android_mk.
## The CPU Features library provides caps and is documented at
## https://developer.android.com/ndk/guides/cpu-features.
##
## At Crypto++ 8.5 we added test_shared.hxx and test_shared.cxx to
## produce libtest_shared.so. The test_shared recipe shows you how
## to build a simple shared object, if desired. A couple wiki pages
## refers to it for demonstration purposes. The test_shared recipe
## can be deleted at any time.
##
## At Crypto++ 8.6 we used architecture specific flags like in the
## makefile. The arch specific flags complicated Android.mk because
## we have to build a local library for each source file with an
## arch option. To see Android.mk before the changes checkout
## CRYPTOPP_8_5_0 tag. If you don't want to build like Android.mk
## does, then add -DCRYPTOPP_DISABLE_ANDROID_ADVANCED_ISA=1 to
## CPPFLAGS. The define disables the advanced ISA code paths used
## by Android.
##
## The library's makefile and the 'make distclean' recipe will
## clean the artifacts created by Android.mk, like obj/,
## neon_simd.cpp.neon and rijndael_simd.cpp.neon.
