Python 2.7을 사용하여 스크립트를 실행하기 위해 우분투에 pymedia를 설치하려고합니다. 그래서 종속성을 추적하여 설치했습니다.
sudo apt-get install python-dev libogg-dev libvorbis-dev liblame-dev libfaad2-dev libasound2-dev python-pygame libmp3lame-dev libevent-dev
따라서 위의 설치를 마쳤을 때 pymedia를 빌드하는 다음 단계에서 다음을 얻었습니다.

인쇄물에서 볼 수 있듯이 패키지는 (제대로 설치되었음에도 불구하고) '찾을 수 없음'으로 언급됩니다. 그리고 오류의 결론은 나에게 gcc 오류처럼 보입니다. 누군가 여기서 무엇이 잘못될 수 있는지 지적할 수 있다면 정말 도움이 될 것입니다.
답변1
아주 많은 사람들이 이 문제를 겪고 있습니다. 이는 아마도 엉망인 스크립트 때문일 가능성이 높습니다.
분명히 64비트 공유 라이브러리는 플래그를 사용하여 컴파일해야 하며 -fPIC이 경우 sound.cpp는 그렇지 않습니다.
여기 에는 setup.py라는 함수가 있습니다 disable_fPIC(). 해당 함수에 속한 모든 코드를 명령문으로 바꾸면 함수를 비활성화할 수 있습니다 pass.그래서:
def disable_fPIC():
pass
