【问题描述】：
我正在尝试使用 Cygwin 和/或 cmd 在 Windows 下为 Android 编译一些 Boost 库。
我按照此处显示的说明进行操作：http://www.boost.org/doc/libs/1_61_0/more/getting_started/windows.html
在我设置好必要的环境变量之后：
//At first I tried with cmd
set NDK_ROOT=C:\android-ndk-r12b
set TOOLCHAIN_PATH=C:\android-ndk-r12b\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64
set PATH=%PATH%;C:\boost_build\bin;%TOOLCHAIN_PATH%\bin
set NO_BZIP2=1
//I also tried with cygwin
TOOLCHAIN_PATH=/cygdrive/c/android-ndk-r12b/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64/
NDK_ROOT=/cygdrive/c/android-ndk-r12b/
PATH=$PATH:/cygdrive/c/boost_build/bin:/cygdrive/c/android-ndk-r12b/:$TOOLCHAIN_PATH/bin
NO_BZIP2=1
现在我正在使用这些参数启动 b2：
b2 --build-dir=C:\boost_builded toolset=gcc link=static threading=multi --with-system --with-date_time --with-random stage
我收到这些错误：
//The errors are the same both in cmd and in cygwin

我什至不确定他没有找到什么路径。我认为它正在寻找“\usr\i686-pc-cygwin\bin\ar.exe”，因为其他路径似乎正确且存在；但我认为它正在寻找“\”，就好像它是linux系统的根目录，而不是在cygwin的子目录中。
如何改正？
【问题讨论】：
-
Cygwin 有自己的根目录。您可以在路径上使用
ls，看看那里有什么。
