在 Windows 10 上使用 mingw 的 CMake：检测 CXX 编译器 ABI 信息 - 失败

Question

I want to use cmake to create MinGW Makefiles on windows 10. I have installed mingw and I can use mingw32-make and g++ commands without issue.

The test project is a super simple CMakeLists.txt file:

cmake_minimum_required(VERSION 3.10)
project(hello-world)
add_executable(hello-world main.cpp)

and a simple main.cpp file:

#include <iostream>
int main() {
    std::cout << "hello Visual Studio Code! :)" << '\n'; 
    return 0;
}

These are the commands I use to create the makefiles:

>> mkdir build
>> cd build
>> cmake -G "MinGW Makefiles" ..

This is where I get errors:

CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.10/Modules/CMakeDetermineCompilerId.cmake:495 (file):
file STRINGS file
"C:/Projects/test/build/CMakeFiles/3.10.1/CompilerIdCXX/a.exe" cannot be read.

... some more errors in the test files

-- The CXX compiler identification is GNU 6.3.0
-- Check for working C compiler: C:/MinGW/bin/gcc.exe
-- Check for working C compiler: C:/MinGW/bin/gcc.exe -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done

-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - failed
-- Detecting CXX compile features
-- Detecting CXX compile features - done
-- Configuring incomplete, errors occurred!

This is from the error log:

The CXX compiler identification could not be found in "C:/Projects/test/build/CMakeFiles/3.10.1/CompilerIdCXX/a.exe"

What is the CXX compiler ABI info and how can it be, that there is a working CXX compiler detected but this fails?

Let me know if you need anymore info about the setup!

Answer 1

What turned out to be my culprit was Windows Defender! Turned that off and the CXX compiler ABI info - failed issue went away.

Answer 2

I used the CMake-GUI tool to figure out the missing tool dependencies. For example : CMAKE_ADDR2LINE was not set, once I pointed it to the correct location of addr2line.exe ,the errors were resolved.
