오류 그 소리에 설치 : http://quantlib.org/install/macosx.shtml에서, 컴파일 예제를 실행에 error: linker command failed with exit code 1 (use -v to see invocation)

,

`

이것은 무엇을 의미하며 왜 LLVM이 호출됩니까? 저는 최신 Xcode, Mac OSX 10.12.1을 사용하고 있습니다. 파이썬에는 익숙하지만 명령 줄 설치 또는 컴파일에는 익숙하지 않습니다. ...

Answer 1

오류는 매우 간단합니다. BermudanSwaption.cpp 만 컴파일했지만 전체 QuantLib도 컴파일해야합니다. 그렇지 않으면 링커가 구현을 찾을 수 없습니다.
