Android ndk 如何为Windows构建NDK LLVM工具链？

我正在尝试为Windows 64位构建NDK LLVM工具链

我已经通过

“download toolchain sources.sh”

下载了源代码

首先，我尝试在Windows-7-64位操作系统上的cygwin64 bash中运行

“build llvm.sh”

我的命令是：

sh build-llvm.sh --verbose --build-out=/cygdrive/d/g//toolchain-llvm --platform=android-14 --try-64 -j4 /cygdrive/d/g/android-toolchain /cygdrive/p/android/android-ndk-r10e llvm-3.5

build-llvm.sh --verbose --build-out=~/toolchain-llvm-out --platform=android-14 --try-64 -j4 --mingw /media/sf_android-toolchain-src ~/android-ndk-r10e llvm-3.5

我有两个错误：

一,

二,

然后，我尝试在安装了mingw64的Ubuntu64上运行

“build llvm.sh”

我的命令是：

sh build-llvm.sh --verbose --build-out=/cygdrive/d/g//toolchain-llvm --platform=android-14 --try-64 -j4 /cygdrive/d/g/android-toolchain /cygdrive/p/android/android-ndk-r10e llvm-3.5

build-llvm.sh --verbose --build-out=~/toolchain-llvm-out --platform=android-14 --try-64 -j4 --mingw /media/sf_android-toolchain-src ~/android-ndk-r10e llvm-3.5

我得到了以下错误：

我读取了在工具链llvm out/llvm中生成的config.log。 它说：

它找不到

“/android-ndk-r10e/。/prebuilts/tools/gccsdk/gcc

”。 这是怎么一回事？该职位不属于NDK本身。 它应该在那里吗

关于bash的警告也很奇怪，因为我确信它在bash中运行

$ echo $SHELL
/bin/bash
$ echo $BASH_VERSION
4.2.25(1)-release

我希望我至少可以在Ubuntu上构建它。请帮忙。谢谢

$ echo $SHELL
/bin/bash
$ echo $BASH_VERSION
4.2.25(1)-release
