Does exist a official build option for Android NDK?
I have found http://stackoverflow.com/questions/17667978/using-boost-in-android-ndk-with-windows

and I use the current NDK r9d for OSX.  The Android NDK defined these toolchains:

arm-linux-androideabi-4.6
arm-linux-androideabi-4.8
arm-linux-androideabi-clang3.3
arm-linux-androideabi-clang3.4
llvm-3.3
llvm-3.4
mipsel-linux-android-4.6
mipsel-linux-android-4.8
mipsel-linux-android-clang3.3
mipsel-linux-android-clang3.4
x86-4.6
x86-4.8
x86-clang3.3
x86-clang3.4

I use at the moment for the Nexus arm-linux-androideabi-4.8. 
I have defined this for running

export NO_BZIP2=1
export NO_ZLIB=1
export AndroidNDKRoot="/Applications/Android/NDK/"
export TOOLCHAIN="arm-linux-androideabi-4.8"
export TARGETOS="arm-linux-androideabi-gcc"
export CXXPATH=$AndroidNDKRoot/toolchains/${TOOLCHAIN}/prebuilt/darwin-x86_64/bin
./b2 link=static threading=multi variant=release install --layout=tagged --prefix=/Applications/Android/Boost/1.55.0/$TOOLCHAIN/

So I get the error:

error: toolset gcc initialization:
error: version 'android' requested but 'g++-android' not found and version '4.2.1' of default 'g++' does not match

How can I get a working build configuration? I don't create a cross-compiling Boost lib, so it is my first try.

Thanks a lot

Phil
