铿锵（3.8）和Android NDK r14b

问题描述：

建设提升（1.58）我尝试使用铿锵3.8建立提升1.58的Android NDK r14b。我已经与gcc正确地工作，但叮当的情况并非如此。铿锵（3.8）和Android NDK r14b

通过运行下面的命令（它是program_options LIB只举一个例子）：

"androidNDK/toolchains/llvm/prebuilt/windows-x86_64/bin/clang++" 
-c 
-x c++ 
-std=c++11 
--stdlib=libc++ 
-mthumb 
-Os 
-O2 
-g 
-Wno-unused-local-typedefs 
-O3 
-Wno-inline 
-Wall 
--sysroot=androidNDK/platforms/android-24/arch-arm 
-I"androidNDK/sources/cxx-stl/llvm-libc++/include" 
-D_GLIBCXX__PTHREADS 
-D__arm__ 
-D_REENTRANT 
-D__ANDROID__ 
-DANDROID 
-pthread 
-std=c++11 
--stdlib=libc++ 
-mthumb 
-fno-strict-aliasing 
-DBOOST_ALL_NO_LIB=1 
-DBOOST_TEST_NO_MAIN 
-DNDEBUG 
-D_HAS_EXCEPTIONS=0 
-D_LITTLE_ENDIAN 
-I"." 
-o "bin.v2\libs\program_options\build\clang-linux-android\release\link-static\runtime-link-static\target-os-linux\threadapi-pthread\threading-multi\config_file.o" "libs\program_options\src\config_file.cpp"

，但我得到的signal.h中文件中的一些错误：

是否有任何人谁已经做了这样的事情，或者可能会看到错误的东西？

看起来像它可能是一个错误。你可以用repro指令提交一份吗？ https://github.com/android-ndk/ndk/issues –

所以它终于为我工作。我意识到signal.h上的那些错误是因为我的编译器的目标没有真正定义。我想建立升压的臂32位，但在“执行配置检查”，它是： - 32位：无 - 64位：是 - 手臂：是

于是，我改变了我的用户配置在的.jam我升压文件夹：

import os ; 
androidNDKRoot = E:/androidNDK ; # put the relevant path 
using clang : android : 
    $(androidNDKRoot)/toolchains/llvm/prebuilt/windows-x86_64/bin/clang++ : 
    <compileflags>--sysroot=$(androidNDKRoot)/platforms/android-21/arch-arm 
    <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++/include 
    <compileflags>-I$(androidNDKRoot)/sources/cxx-stl/llvm-libc++abi/include 
    <compileflags>-I$(androidNDKRoot)/sources/android/support/include 
    <compileflags>-g 
    <compileflags>-Os 
    <compileflags>-O2 
    <compileflags>--target=armv7a-none-linux-androideabi 
    ;

看来，铛没有像在海湾合作委员会的选项，所以我加在PATH变量他们共同的绝对路径：

set PATH=%PATH%;E:\androidNDK\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\arm-linux-androideabi\bin\

，并测试一个构建（例如：原子），我执行从我的助推文件夹：

b2.exe --user-config=tools\build\src\build\user-config.jam target-os=android toolset=clang-android link=static runtime-link=static variant=debug threading=multi -q -a -j6 --with-atomic
