Windows下編譯使用NDK編譯Boost庫

背景

安卓開發中需要使用線程庫

準備工作

1. 下載ndk10e：地址
2. 下載boost庫：boost_1_69_0.zip
3. 將“android-ndk-r10e-windows-x86.zip”和“boost_1_69_0.zip”解壓到G盤根目錄，得：“G:\boost_1_69_0\”和"G:\android-ndk-r10e"

成功編譯的步驟

1. 運行"G:\boost_1_69_0\bootstrap.bat"
2. 替換"G:\boost_1_69_0\project-config.jam"文件的內容，可複製下文：

# define platform name of ndk
import os ;
if [ os.name ] = CYGWIN || [ os.name ] = NT
{
    androidPlatform = windows ;
}
else if [ os.name ] = LINUX
{
    androidPlatform = linux-x86_64 ;
}
else if [ os.name ] = MACOSX
{
    androidPlatform = darwin-x86 ;
}

# replace with your own path
ANDROID_NDK = "G:/android-ndk-r10e" ;

# compile with gcc, you can change compiler to clang or others

# project default compiler
project : default-build <toolset>gcc-4.9 ;

# replace with libraries you wanna to build
#libraries = --with-container --with-coroutine --with-fiber --with-graph --with-graph_parallel --with-log --with-python --with-test --with-type_erasure --with-atomic --with-date_time --with-program_options --with-chrono --with-context --with-iostreams --with-locale --with-mpi --with-serialization  --with-timer --with-wave --with-math --with-random --with-exception --with-filesystem --with-thread --with-system --with-regex --with-program_options ;

libraries = --with-thread ;

1. 打開cmd窗口，切換當前目錄到"G:\boost_1_69_0",執行命令

.\b2.exe link=static runtime-link=static target-os=linux --stagedir=android

遇到的問題

找不到g++

報錯的部分內容如下：

G:/boost_1_69_0/tools/build/src/tools\gcc.jam:164: in gcc.init from module gcc
error: toolset gcc initialization:
error: provided command 'G:/android-ndk-r10e/toolchains/arm-linux-androideabi-4.
9/prebuilt/windows-x86_64/bin/arm-linux-androideabi-g++' not found
error: initialized from project-config.jam:56

覈對文件的路徑發現，其真實的路徑應該爲"G:/android-ndk-r10e/toolchains/arm-linux-androideabi-4.
9/prebuilt/windows/bin/arm-linux-androideabi-g++",觀察“project-config.jam”發現，路徑中的只有“windows”沒有“-x86_64”,所以需要刪除。如下圖所示~~~~

參數錯誤

報錯的部分內容如下：

Performing configuration checks

    - default architecture     : arm

    - lockfree boost::atomic_flag : no

ers.less' being called~~~~

根據提示，查看文件“G:/boost_1_69_0/tools/build/src/tools\common.jam”的第973行，如下圖所示：猜測與gcc的版本有關係，而從參考文檔1中複製的配置文件中有關於gcc的內容只有如圖所示的部分：，統合錯誤提示，猜測與前面的android有關，刪除後再次嘗試，編譯成功

延伸思考

1. 配置文件中已經指定了默認的toolset，所以不用在命令行中再次指定了，同理,需要編譯的library也在配置文件中指定了，也不需要在命令行中再次指定，故，相比與參考文檔，第3步的命令更短、更方便。猜測可以全部放到配置文件中，命令僅.\b2.exe，應該也行~~~~

參考文檔

1. Windows下NDK直接編譯編譯boost 1.55（X86版本)
2. ubuntu16.04編譯boost for Android
3. boost_for_android
