no archive symbol table (run ranlib) while building libcryptopp.a through ndk-build

After you build the Crypto++ library through Android.mk, you need to run ranlib on libcryptopp.a. Unfortunately, I don't know how to tell Android.mk to run ranlib.

I'm guessing - and its purely a guess - that you have to do this in two steps in Android.mk. You cannot cut to the chase and build the shared object directly from sources.

  • build libcryptopp.a, running ranlib
  • build libcryptopp.so from libcryptopp.a

setenv-android.sh its while creating libcryptopp.a and .so by using cryptopp 5.6.3
...
APP_STL = gnustl_static

The script setenv-android.sh uses STLport because of GNU licensing encumbrances. Your Android.mk uses GNU's STL.

You should probably also use the same C++ runtime libraries. Additionally, all libraries must use the same runtime. That means OpenGL, Crypto++, [Favorite library], must use the same C++ runtime, and there's no mixing and matching. In addition, because multiple libraries are using the C++ runtime, you must use the shared object, and not the static version.

There's a README in the NDK somewhere that discusses it. I think its called CPP-README or similar.

Also, when you invoke the setenv-android.sh, you must include a leading dot. Then you run the GNUmakefile-cross:

. ./setenv-android.sh
make -f GNUmakefile-cross static dynamic cryptest.exe

Finally, please don't post pictures. I can barely read them because my eyes are old. Usually, appeasing one user does not matter. In this case, I'm the guy who wrote the scripts and the wiki pages, so you want to make it easy on me, and not hard on me :)
