모든 것에 대한 CMake + MSys2 정의되지 않은 참조 (C ++ 런타임 포함)

저는 크로스 플랫폼 C ++ 프로젝트를 개발하고 있습니다. Linux에서는 잘 구축되지만 Windows (10) + MSys2에서는 이상한 문제가 발생했습니다. 컴파일은 잘 작동하지만 (내 include dirs 등을 선택합니다.) 내가 가지고있는 정적 가져온 라이브러리와 C ++ 런타임에 대한 모든 종류의 정의되지 않은 참조 오류로 인해 연결이 실패합니다.

CMAKE_C [XX] _COMPILER, CMAKE_MAKE_PROGRAM 설정을 시도했지만 구성 단계의 출력은 항상 동일합니다.

$ cmake ..

앞서 언급했듯이 컴파일은 작동하지만 실행 파일 연결은 눈에 띄게 실패합니다. 다음은 최소한의 작업 예입니다.

$ cat ../CMakeLists.txt
project(example)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)

add_executable(example
        main.cpp
)

다음은 출력 샘플입니다 (나머지는 간결함을 위해 생략 됨).

C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/10.2.0/../../../../x86_64-w64-mingw32/bin/ld.exe: CMakeFiles/example.dir/main.cpp.obj:main.cpp:(.text+0x51): undefined reference to `std::ios_base::Init::~Init()'

cmake에 -v를 추가하면 다음 명령이 생성됩니다.

엮다:

/mingw64/bin/CC.exe   -std=gnu++17 -o CMakeFiles/example.dir/main.cpp.obj -c /home/.../Development/minex/main.cpp

링크:

/mingw64/bin/CC.exe CMakeFiles/example.dir/main.cpp.obj -o example

CC.exe가 꺼진 것 같고 CXX 컴파일러 플래그를 설정하거나 설정하지 않으면 사용됩니다.

또한 "MSYS2 Makefiles"생성을 시도했지만 실패했습니다 (생성기를 알지 못함).

실행하는 것으로 출력을 재현 할 수 있습니다

$ CC main.cpp -o example

동안

$ g++ main.cpp -o example

잘 작동합니다.

CMake 버전은 3.18.4입니다.

편집 : 이것은 실행의 전체 출력입니다 make VERBOSE=1( mingw64-cmake'입력 디렉토리'와 '이탈 디렉토리'경로가 절대 Windows 경로 임을 제외하고는 동일한 출력을 생성하는 것 같습니다) :

해결책:

CMAKE_CXX_COMPILER를 잘못 설정했습니다 : /. 나는 기억에서 그것을하고 있었고

CMAKE_CXX_COMPILER=... cmake ..

아니

cmake .. -DCMAKE_CXX_COMPILER=...

하나! CC가 cpp 파일을 성공적으로 컴파일하는 데 사용되는 것이 여전히 이상하지만 개체 파일을 연결할 수 없습니다.
