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-7-64bits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
我有两个错误：
1
ERROR: Unsupported HOST_TAG: cygwin-x86_64
2
Makefile:152: D:/cygdrive/d/g/android-toolchain/llvm-3.5/llvm/Makefile.rules: No such file or directory
make: *** No rule to make target `D:/cygdrive/d/g/android-toolchain/llvm-3.5/llvm/Makefile.rules'. Stop.
然后，我尝试在安装了mingw64的Ubuntu64上运行"build-llvm.sh"。
我的命令是：
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
我收到以下错误：

ERROR: Couldn't configure llvm toolchain
我读了toolchain-llvm-out / llvm中生成的config.log。 它说：

configure:4376: error: installation or configuration problem: compiler cannot create executables.
找不到"/android-ndk-r10e/../prebuilts/tools/gcc-sdk/gcc“。
它是什么？这个位置在NDK本身之外。
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

我希望我至少可以在Ubuntu上构建它。请帮忙。感谢。
