Windows 上的 Clang 和 CMake - clang.exe 損壞，程序不可執行

Question

我已經在 Windows 上設置了 Clang 和 CMake，當在 OpenSceneGraph 項目源（配置步驟）上運行 cmake-gui 時，該過程失敗並Check for working C compiler: C:/Program Files (x86)/LLVM/bin/clang.exe -- broken 。

在整個輸出之后：

The C compiler identification is unknown
The CXX compiler identification is unknown

Check for working C compiler: C:/Program Files (x86)/LLVM/bin/clang.exe -- broken

  The C compiler "C:/Program Files (x86)/LLVM/bin/clang.exe" is not able to

  It fails with the following output:

這可能是什么原因？ 程序之間是否不兼容，或者是否缺少環境變量？

Answer 1

您的 clang 安裝已損壞/未完成，或者可能是 cmake錯誤。 首先檢查您是否能夠直接使用 clang 編譯“hello world”（不使用 cmake）

Answer 2

您需要確保將 Visual Studio 生成器與正確的工具集用於 clang

不知道cmake-gui有沒有設置工具集的方法，所以改用命令行試試。

cmake.exe .. -T LLVM-vs2010

Answer 3

確保您的 sdk 方向沒有一些特殊字符，例如：'(',')',' '。 通過 .txt 閱讀器檢查日志。 日志在 .externalNativeBuild/cmake/debug/...

Answer 4

正如此鏈接中所述，Windows 上的clang必須能夠找到link.exe 。

我使用舊的 Visual Studio Express 版鏈接器對其進行了測試，並且運行良好。
