LNK2019 : 해결되지 않은 외부 기호 _WinMain @ 16이 함수에서 참조했습니다. ___tmainCRTStartup

Question

이 오류를 해결하기 위해 이미 2 시간 씩 인터넷을 검색하여 많은 사람들이이 오류를 발견했지만 내 자신의 경우에 대한 해결책을 아직 찾지 못했습니다.

대개의 경우 솔루션은 솔루션의 속성 (콘솔 또는 Windows)에서 서브 시스템을 적절한 옵션으로 변경하는 것입니다. 하지만 내 것은 창문에 맞춰져 있는데, 내 경우에는 맞는 창문입니다. 내가 파일> 새로 만들기> 프로젝트> Win32 프로젝트> (선택) Windows 응용 프로그램> 사용이 솔루션을 생성 할 때 (체크)

내 문자 세트가 나는 기본적 생각 유니 코드로 설정

빈 프로젝트. 정보가 여전히 문의하시기 바랍니다 필요가있는 경우

감사

Answer 1

WinMain을 C++ 네임 스페이스에 넣습니다. WinMain()은 응용 프로그램 네임 스페이스가 아닌 전역 네임 스페이스에서 자유 함수 여야합니다.
