I've just built and installed cmake 3.16 on a fresh WSL install (Ubuntu18.04 LTS). I then created a default hello world project

(base) ciaran@DESKTOP-K0APGUV:/mnt/d/ATest$ tree .
.
├── CMakeLists.txt
└── main.cpp

//CMakeLists.txt
cmake_minimum_required(VERSION 3.15)
project(ATest)

set(CMAKE_CXX_STANDARD 14)

add_executable(ATest main.cpp)

//main.cpp
#include <iostream>

#include <string>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

And then tried to build:

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

And I get the following.

I originally tried cmake 3.15 but upgraded to see if it was a version problem, given this, I don't this it is. I've also tried g++-7 and g++-9 which behave the same.

Does anybody know what might be going on here? Thanks.

  • Definitely not a GCC problem, it doesn't get that far. WSL suggests that the CMakeListst.txt fle may be in DOS format (CRLF), not Unix. `dos2unix CMakeLists.txt` would fix that. – MSalters Jul 13 '20 at 15:50
  • I wouldn't have thought of that. I tried running `dos2unix CMakeLists.txt` and rebuilding from clean build directory and I got the same problem. – CiaranWelsh Jul 13 '20 at 15:59

    Googling the issue led me to this [post](https://github.com/microsoft/WSL/issues/4257#issuecomment-507799403) describing a similar problem with a potential solution. – Kevin Jul 13 '20 at 16:02

  1. Create a file named wsl.conf in /etc/ with the following text:
# /etc/wsl.conf
[automount]
options = "metadata"
enabled = true
  1. Reboot wsl:

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

I was able to fix the above error by running the following commands in order:

% cd build
% cmake -B . -S ..
% cmake --build .

This solution is taken from here.
