CLAM project의 예제를 빌드하고 연결하려고합니다. 나는 다음 오류를 링크하고 얻는다. 나는 틀린 것을 모른다.링커에서 오류가 발생했습니다. C++ linux Scons : CLAM project

아무에게도 도움이 될 수 없습니다. 어떤 변화하는 I는 다음과 같습니다 SConstruct 할 수 있도록해야합니다

libdl이 누락 된 것처럼 보입니다. 당신이 그것을 어디에 추가하는지 잘 모르겠습니다. 덕분에 – cup
; 나는 그렇게 생각하지만 어디에서, 나는 너무 궁금해하고있다. – telcom
아마도 CPPPATH를 설정 한 후 env.Append (LIBS = [ 'dl'])와 같은 것일 수도있다. – cup
