제가 만든 UnrealMemory 이름의 프로젝트에 있는 여러 소스파일들을 UnrealMemory2 라는 이름의 새로운 언리얼엔진 프로젝트를 만들어 해당 소스폴더에 붙여넣은 후, UNREALMEMORY2_API로 전부 바꾸고 UnrealMemory2 프로젝트를 개별 빌드하면 아래와 같이 오류없이 빌드가 성공하나,

binaries 와 save, derivedcaches, intermediate 폴더를 삭제하고 시도하였으며, .uproject로 generate Vs project files 를 실행해도 동일하게 콘솔창이 뜨게 됩니다.

 

정상적으로 에디터를 실행하기 위해선 어떤 방법이 필요한지 알고싶습니다.

아래 오류로 보건데 이전에 작업한 빌드 프로세스가 죽지 않고 해당 파일을 계속 점유하고 있어서 문제가 발생하는게 아닌가 싶네요. 리부팅을 한 번 해보시겠어요?

(12>Unhandled exception: System.IO.IOException: The process cannot access the file 'F:\LeeProject\UnrealMemory2\Intermediate\Build\Win64\x64\UnrealGame\DebugGame\UnrealMemory2\MyGameInstance.cpp.obj.rsp' because it is being used by another process.

컴퓨터 리부팅을 하고 다시 f5를 눌러보았지만 여전히 에디터가 실행되지 않고, 콘솔창과 동일한 내용이 출력이 됩니다.

그리고 아래에는 막 마친 솔루션빌드를 진행 후 출력된 결과입니다.

(잘 몰라서 빌드내용을 전부 긁어왔습니다만, 당장 해결하지 않아도 진도를 나가는데 있어서 지장이 없기 때문에 해결하지 못한채로 넘어가도 아무 문제 없습니다.)

네 아마도 제가 소스코드를 받아서 조사해봐야 문제를 해결해드릴 수 있을 것 같네요.
검색해보니, 관련 에러는 기존 소스를 수정하면서 코딩할 때, 이전 코드의 파편이 남아 발생하는 것처럼 보입니다.
가급적이면 처음부터 깔끔하게 새롭게 만들어보시는 것도 권장드립니다.
언리얼 엔진은 복붙도 구조를 알아야 가능하거든요.
