을 포함하는 오류가 발생했습니다. 따라서 OpenMP를 사용하여 일부 C++ 코드를 병렬 처리하려고 시도하지만이 이상한 오류가 계속 발생합니다. 컴파일러는 라이브러리와 모든 것을 찾습니다.하지만 라이브러리 자체에 오류가 있습니다.<omp.h> (C++)
In function 'void set_num_threads(int)':
error: expected primary-initialization before ',' token
오류가이 라인에서 발생합니다 :
extern void omp_set_num_threads (int) __GOMP_NOTHROW;
를 ...하지만 그것은 또한 파일이 정의하는 거의 모든 다른 기능에 오류가 있습니다 그것은 말한다. 컴파일러에 문제가 있다는 것을 알았지 만, 어떻게 될지 또는 어떻게 고칠 수 있는지 모르겠습니다. 도움말 크게 감사드립니다. 고맙습니다.
업데이트 온라인 컴파일러에서 코드를 실행 해 보았는데 동일한 오류가 발생하여 어떤 점이 잘못 됐는지를 알 수 없습니다.
좋아, 제 교수가 가지고있는 난수 생성기를 포함하여 문제가 발생하는 것 같습니다. 이것은 .h 파일의 코드입니다. 내가 넣어 전에 'omp.h을 포함'하는 경우
