Android NDK, Crypto++, GNUmakefile.

Cześć,

Próbuje wykorzystać bibliotekę Crypto++ w aplikacji na Androida. Jedyny poradnik jaki znalazłem jak to zrobić to ten: http://www.cryptopp.com/wiki/Android_(Command_Line) . Niestety zaciąłem się na "patchowaniu" GNUmakefile. Nie wiem skąd mogę wziąć plik, który jest tam wspomniany GNUmakefile-android.patch. Próbowałem pozmieniać makefile ręcznie, ale nie wiem czy robię to poprawnie. Google niestety nie pomaga. Aktualnie mój GNUmakefile wygląda tak:

 CXXFLAGS = -DNDEBUG -g -O2
# -O3 fails to link on Cygwin GCC version 4.5.3
# -fPIC is supported. Please report any breakage of -fPIC as a bug.

# the following options reduce code size, but breaks link or makes link very slow on some systems

Niestety po odpaleniu komendy 'make static dynamic cryptest.exe' wywala mi taki błąd:

compilation terminated.
GNUmakefile:233: polecenia dla obiektu 'shacal2.o' nie powiodły się
make: *** [shacal2.o] Błąd 1

Podejrzewam, że GNUmakefile nie korzysta ze zmiennych środowiskowych, które wcześniej ustawiłem i dlatego ten błąd się wywala. Korzystam z cygwina. Jeśli przydałyby się jeszcze jakieś informacje to proszę dać znać.

Pozdrawiam i proszę o pomoc.
