Well, we kind of need to know what's in the libcryptopp.so you built. Can
you verify the symbol is missing?
Below is from a command line build using NDK r10e, armeabi, android-21 and
GNU STL library (I believe they match your setup). The symbol is present.
My guess is you have a path problem, or "$(TARGET_ARCH_ABI)/libcryptopp.so"
is not present or its the wrong architecture. But its only a guess. You
might want to try:
LOCAL_MODULE := cryptopp
LOCAL_SRC_FILES := $(TARGET_ARCH_ABI)/libcryptopp.so
LOCAL_SHARED_LIBRARIES := cryptopp
...
You might also want to look at
https://www.cryptopp.com/wiki/Android_(Command_Line) and
https://github.com/weidai11/cryptopp/pull/3 .
