you try to build for i386 instead arm

How can I make it use arm instead?

I assume you try to cross compile : http://www.boost.org/doc/libs/1_61_0/libs/context/doc/html/context/architect...

I am indeed trying to cross compile, however I am not familiar with b2 nor do I much care to learn it (since it's a means to an end for me to build boost).

Can you provide an example of how I can specify the documented settings to b2 for my build? Do I provide the values to those in my project-config file?

Would really love help with this guys. I literally can't find info on this anywhere else. Surely someone has had success getting 1.61 building with NDK + ARM + Clang.

I made a best-guess using the context cross compiling settings linked earlier. Does this seem correct? It doesn't build at the moment saying it can't find locale-related symbols. That doesn't help me at all so I guess I'm going to have to dig into the llvm STL code and find out what preprocessor flags I'm missing (assuming it's that simple). Also I still don't know how to specify 'ar' and 'ranlib' executables to boost from NDK.

using clang : android : $(androidNDKRoot)/toolchains/llvm/prebuilt/$(androidPlatform)/bin/clang++ : <compileflags>--sysroot=$(androidNDKRoot)/platforms/android-15/arch-arm <compileflags>-Os <compileflags>-fno-strict-aliasing <compileflags>-O2 <compileflags>-DNDEBUG <compileflags>-g <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++abi/libcxxabi/include <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++/libcxx/include <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++/libs/armeabi-v7a <compileflags>-I$(androidNDKRoot)/sources/android/support/include <compileflags>-DANDROID <compileflags>-D__ANDROID__ <compileflags>-D__arm__ <compileflags>-D_REENTRANT <architecture>arm <address-model>32 <binary-format>pe <abi>aapcs ;

FYI: I still haven't gotten this working. Sorry to keep bumping this thread but I have absolutely zero options yet. I need help from the boost developers at this point, I think.
