Linux 的 Windows 子系统中缺少 C 和 C++ 编译器

Question

我正在尝试使用 Windows 子系统为 Linux (Windows 10 build 10.0.14342) 编译 LLVM，但我不断收到关于我如何运行的 cmake 错误缺少 C 和 C++ 编译器。尽管通过使用 bash 中的 apt-get 获得了 gcc、g++ 和 build-essentials，但还是如此。我的命令如下：

cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86" ../llvm-3.8

我从 CMake 收到一堆错误

  try_compile() works only for enabled languages.  Currently these are:

    ASM C CXX

  See project() command to enable other languages.

CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:61 (message):
  The C compiler "/usr/bin/cc" is not able to compile a simple test program.

  It fails with the following output:

我不确定发生了什么，因为我能够成功地使用 gcc 和 g++ 编译 helloworld 程序。

原来这是一个已知错误：https://github.com/Microsoft/BashOnWindows/issues/272

长话短说，自 build 14352 起已修复。
