내가 알고있는 라이브러리의 링커 오류가 프로젝트에 있습니다.

Question

그래서 저는 3dar SDK를 사용하고 있으며 sdk와 결과 SM3Dar.h 헤더를 구현 한 독립 실행 형 응용 프로그램을 빌드하는 데 아무런 문제가 없었습니다. 하지만 이제는 더 큰 프로젝트의 일부로 동일한 SDK를 사용하려고 시도 했으므로 제대로 작동하지 않는 것 같습니다. 헤더 파일이 거기에 있다는 것을 알 것 같지만 그 파일과 라이브러리와 올바르게 통신하지 않습니다. 나는 iPhone 5에서 실행하려고하는데 최신 Xcode가 있습니다.

는하지만 이러한 오류가

Answer 1

내가하지 armv7s를하는 ARMv7 라이브러리만을 위해 지어진 생각받을 수 있습니다. 이것이 문제인지 확인하려면 프로젝트 빌드 설정에서 armv7 용으로 빌드하도록 프로젝트를 구성하고 해당 빌드가 작동하는지 확인하십시오. 이 경우 라이브러리의 업데이트 된 버전을 얻거나 armv7 용 코드 만 빌드하면됩니다.

Add "-lc++" to Other Linker Flags in your Build Settings.
