因此,我正在尝试在 Windows 10 上构建一个 CMake 项目,我安装了 Visual Studio 2019 和 CMake 以及所有 C++ 工具。但是,当尝试在 Visual Studio 开发人员命令提示符或 Visual Studio 开发人员 PowerShell 中运行 cmake -S external\ebpf-verifier -B external\ebpf-verifier\build 时,我遇到了奇怪的行为。这是在 Developer PowerShell 中运行的结果。我在命令行版本中得到了类似的结果。在命令提示符中运行它的一个主要区别是 pwd 导致 /d/ebpf-for-windows 作为当前导向器,而 PS 导致 D:\ebpf-for-windows。我认为这是因为我安装了 Devkitpro,这就是为什么我有 /c/ 和 /d/ 但是我什至没有运行 devkitpro 版本,所以必须有一些配置或环境变量指向它。

D:\ebpf-for-windows>cmake -S external\ebpf-verifier -B external\ebpf-verifier\build -- C编译器标识为MSVC 19.28.29915.0 -- CXX编译器标识为MSVC 19.28.29915.0 --检查工作的 C 编译器:/c/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/VC/Tools/MSVC/14.28.29910/bin/HostX86/x86/cl.exe -- 检查工作的 C 编译器: /c/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/VC/Tools/MSVC/14.28.29910/bin/HostX86/x86/cl.exe - /opt/devkitpro/msys2/usr/处的CMake错误share/cmake-3.17.3/Modules/CMakeTestCCompiler.cmake:60(消息):C 编译器

"/c/Program Files (x86)/Microsoft Visual Studio/2019/Enterprise/VC/Tools/MSVC/14.28.29910/bin/HostX86/x86/cl.exe"

无法编译简单的测试程序。

它失败并显示以下输出:

CMake 将无法正确生成此项目。调用堆栈(最近调用优先):CMakeLists.txt:4(项目)

-- 配置不完整,出现错误!另请参阅“/d/ebpf-for-windows/external/ebpf-verifier/build/CMakeFiles/CMakeOutput.log”。另请参阅“/d/ebpf-for-windows/external/ebpf-verifier/build/CMakeFiles/CMakeError.log”。

是我要开始工作的 GitHub 项目,这里是设置步骤。

错误消息说“-o is deprecated”,似乎被忽略了,编译器正在尝试构建指定的“.co”文件。删除“-o”和相应的参数,然后重试。
