Arch Linux: cuda로 opencv를 빌드하는 중에 문제가 발생했습니다. libopencv_core.so.3.4.0: 'cblas_dgemm'에 대한 정의되지 않은 참조입니다.

저는 현재 내 아치 리눅스 머신에 cuda가 포함된 opencv 버전을 구축하려고 합니다. 이를 위해 나는 사용합니다opencv-cuda-git기본 버전으로. 또한 PKGBUILD를 수정하고 opencv를 내 시스템에 추가로 적용하기 위해 추가 플래그를 추가했습니다.

그러나 빌드 프로세스(makepkg csri)를 실행할 때마다 다음 오류 메시지와 함께 실패합니다.

이전 검색에 따르면 이 오류는 cublas의 연결 오류로 인해 발생할 수 있습니다. 그래서 추가해봤는데-L/opt/cuda/lib64그리고-루쿠브라스도착하다CMAKE_CXX_FLAGS. 전혀 차이가 없습니다.

또 다른 블로그에서는 g++-6 대신 gcc-6을 사용하는 것을 제안합니다. 그러나 이렇게 하면 또 다른 오류가 발생합니다.
