在 WSL 上对 configure_file 的每次调用都会失败：configure_file 配置文件有问题

Question

我刚刚在全新的 WSL 安装 (Ubuntu18.04 LTS) 上构建并安装了 cmake 3.16。然后我创建了一个默认的 hello world 项目

\n

(base) ciaran@DESKTOP-K0APGUV:/mnt/d/ATest$ tree .\n.\n\xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 CMakeLists.txt\n\xe2\x94\x94\xe2\x94\x80\xe2\x94\x80 main.cpp\n

\n

//CMakeLists.txt\ncmake_minimum_required(VERSION 3.15)\nproject(ATest)\n\nset(CMAKE_CXX_STANDARD 14)\n\nadd_executable(ATest main.cpp)\n

\n

//main.cpp\n#include <iostream>\n\n#include <string>\n\nint main() {\n    std::cout << "Hello, World!" << std::endl;\n    return 0;\n}\n\n

\n

然后尝试构建：

\n

(base) ciaran@DESKTOP-K0APGUV:/mnt/d/ATest$ mkdir build\n(base) ciaran@DESKTOP-K0APGUV:/mnt/d/ATest$ cd build/\n(base) ciaran@DESKTOP-K0APGUV:/mnt/d/ATest/build$ cmake ..\n

\n

我得到以下信息。

\n

我最初尝试了 cmake 3.15，但升级后看看是否是版本问题，考虑到这一点，我不这么认为。我也尝试过g++-7并且g++-9其行为相同。

有人知道这里会发生什么吗？谢谢。

1. wsl.conf使用以下文本在 /etc/ 中创建一个名为的文件：

# /etc/wsl.conf
[automount]
options = "metadata"
enabled = true

2. 重新启动 wsl：

wsl.exe -t Ubuntu // (or other e.g. Debian)
