답변1
cmake이전에 설정된 모든 변수를 덮어쓴다고 가정하고 Ubuntu 컴퓨터에서 opencv 디렉터리를 복사했습니다 . 그런데 CMakeCache.txt를 덮어쓰지 않아서 경로가 잘못 인식되는 것 같아요.
쉬운 수정:
- 다음에서 깨끗한 opencv 배포판을 다운로드하세요.http://opencv.org/
- 이전과 같이 튜토리얼을 따르세요.
답변2
첫째, 시스템이 최신 상태가 아닙니다. pacman -Syu.gcc 버전이 5.2.0이라고 말씀하셨습니다 . 현재 버전은 6.3.1입니다. 그래서 어떻게든 CMake는 /usr/bin/gcc-5대신에 통지하는 것을 사용하고 싶어합니다 /usr/bin/gcc.
둘째,ABS. 로컬 ABS 트리가 최신 상태인지 확인할 수 있습니다. 그런 다음 /var/abs/extra/opencv디렉터리에 복사 하고 makepkg.
셋째, 어떤 이유로 ABS를 사용하고 싶지 않더라도 /usr/local아치 리눅스에서는 사용하면 안 됩니다. 바라보다https://wiki.archlinux.org/index.php/Arch_packaging_standards#Directories. 을 사용해야 합니다 /usr.
