Re: [Boost-users] Boost and Android NDK

The important thing is specifying the ARM architecture. The fact that the chip is running Android is not that important for native code.

Hello,

I would like to use Boost on Nexus tablets. I have used Boost at the moment on desktop systems (OSX, Linux, Windows), so my question can I use Boost e.g. random, asio, ublas, . on a Nexus? I would like to build Boost myself, so imho I must build Boost with the NDK compilers and linker, is this correct? Can I build Boost libs in "one shot"? So the NDK has got tools for arm-linux, mipsel- linux and so on. Does anybody can tell me any hopeful tips to use Boost with Android

Before you start worrying about 'building Boost', are you certain you need/want Boost libraries that *must be built*, rather than just #include headers?

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

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
