Question

我在Windows上设置了Clang和CMake，当在OpenSceneGraph项目源（配置步骤）上运行cmake-gui时，该过程失败并显示Check for working C compiler: C:/Program Files (x86)/LLVM/bin/clang.exe -- broken。

跟随整个输出：

The C compiler identification is unknown
The CXX compiler identification is unknown
Found Eclipse version 4.3 ()
Check for working C compiler: C:/Program Files (x86)/LLVM/bin/clang.exe
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
  compile a simple test program.

  It fails with the following output:

这可能是什么原因？程序之间是否存在不兼容性，或者是否缺少环境变量？

Answer 1

您的clang安装是否已损坏/未完成，或者可能是cmake bug。首先检查你是否能够编译＆＃34; hello world＆＃34;直接用clang（没有cmake）

Answer 2

您需要确保将Visual Studio生成器与clang

的正确工具集一起使用

我不知道cmake-gui是否有办法设置工具集，所以请尝试使用命令行。

cmake.exe .. -T LLVM-vs2010

Answer 3

确保您的sdk方向没有某些特殊字符，例如：'（'，'）'，''。通过.txt阅读器检查日志。日志位于.externalNativeBuild / cmake / debug /...

Answer 4

如本link所述，Windows上的 clang 必须能够找到 link.exe 。

我使用旧的Visual Studio Express版本链接器对其进行了测试，并且效果很好。

Windows上的Clang和CMake - clang.exe坏了，程序不可执行
