I'm using NDK r11 and I'm setting up project-config.jam to build boost using clang + llvm STL. I'm running into a few errors that I do not know how to solve. I will post my config file at the bottom. First problem is that boost does not know where to find tools 'ar' and 'ranlib': clang-linux.archive bin.v2\libs\container\build\clang-linux-android\release\link-static\runtime-link-static\target-os-linux\threading-multi\libboost_container-clang-mt-s-1_61.a '"ar"' is not recognized as an internal or external command, operable program or batch file. '"ranlib"' is not recognized as an internal or external command, operable program or batch file. How can I explicitly specify the NDK path to these executables? Second problem is related to some assembler stuff, I think. I get these errors while compiling boost thread: clang-linux.compile.asm bin.v2\libs\context\build\clang-linux-android\release\link-static\runtime-link-static\target-os-linux\threading-multi\asm\make_i386_ms_pe_gas.o libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:1: error: unknown directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:22: error: unknown directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:36: error: expected identifier in directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:30:40: error: unknown directive .def _make_fcontext; .scl 2; .type 32; .endef ^ libs\\context\\src\\asm\\make_i386_ms_pe_gas.asm:136:1: error: unknown directive .def __exit; .scl 2; .type 32; .endef ^ How can I solve this?

First problem is that boost does not know where to find tools 'ar' and 'ranlib':

clang-linux.archive bin.v2\libs\container\build\clang-linux-android\release\link-static\runtime-link-static\target-os-linux\threading-multi\libboost_container-clang-mt-s-1_61.a '"ar"' is not recognized as an internal or external command, operable program or batch file. '"ranlib"' is not recognized as an internal or external command, operable program or batch file.

How can I explicitly specify the NDK path to these executables?

Second problem is related to some assembler stuff, I think. I get these errors while compiling boost thread:

How can I solve this? I have no idea at this point.

I'm invoking the build using:

b2 --without-python threading=multi link=static runtime-link=static toolset=gcc-android target-os=linux threadapi=pthread --stagedir=android stage

And my project-config.jam looks like:

import option ;

option.set keep-going : false ;

Thwe first problem is a boost build issue and the second problem is a context lib issue. Separating these into separate posts might be helpful, with the first going to the build mailing list and the second having [context] start its subject line.

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.
