我尝试使用arm64-v8a的ndk-build构建Boost 1.58.0，但我遇到了问题。
当我运行bjam时，它会以错误unrecognized command line option '-m64'完成。
我发现了一些错误，而且＃34;执行配置检查＆＃34;部分 如：
- 32-bit : no
- 64-bit : yes
- arm : no
...
我想arm字段应该是yes，而且当我为armv7-a构建它时，它会有很大不同。 armv7-a的相应构建始终成功。
[环境]
使用的构建命令是
./bjam toolset=gcc-ndk10.android.21.arm64v8a.4.9 link=static \
runtime-link=static target-os=linux --stagedir=output/arm64-v8a \
--disable-filesystem2 -sICONV_PATH=/home/weareff/local.r10/arm64-v8a/include
我的user-config.jam文件如下：

您可以尝试按照配置选项进行操作：
BS_CONFIG_EXTRA := -d2 -q toolset=gcc architecture=arm abi=aapcs address-model=64
./bootstrap.sh && ./b2 $(BS_CONFIG_EXTRA)
我已成功编译了aarch64硬件中的boost 1.58.0库。
问候。

架构检查手臂说＆＃34; no＆＃34;应该由{boost_root} /libs/config/checks/architecture/arm.cpp中的文件引起，该文件包含以下内容：
#if !defined(__arm__) && !defined(__thumb__) && \
!defined(__TARGET_ARCH_ARM) && !defined(__TARGET_ARCH_THUMB) && \
!defined(_ARM) && !defined(_M_ARM)
#error "Not ARM"
#endif
arm64 gcc无法编译此文件，我们可以通过添加＆＃34; aarch64 ＆＃34;来修补它，所以它变为：
#if !defined(__arm__) && !defined(__thumb__) && \
!defined(__TARGET_ARCH_ARM) && !defined(__TARGET_ARCH_THUMB) && \
!defined(_ARM) && !defined(_M_ARM) && !defined(__aarch64__)
#error "Not ARM"
#endif
这可能使架构检查认识到这是arm平台。
