TL : DR - Chromium을 제 3 자 Mac OS X 프레임 워크에 제대로 연결하기 위해 Build.gn 파일 내에서 올바른 호출은 무엇입니까? Contents/Frameworks/app 번들 경로에 있음)?Chromium : GN/Ninja - Build.gn을 통해 OS X 프레임 워크에 연결하지 못함
내 Build.gn 및 경로 설정은 아래를 참조하십시오.
제 3 자 라이브러리를 통한 비디오 캡처에 대한 지원을 추가하여 Chrome 브라우저를 사용자 정의하고 있습니다. 필자는 기존 Build.gn 파일을 수정하여 제 3 자 deps를 찾고 새로운 소스를 컴파일했습니다.
미디어/캡처/비디오/맥/DEPS : 필자 나의 새로운 종속성을 포함하는 기존 크롬 Build.gn을 수정
include_rules = [
"+third_party/decklink",
"+third_party/Syphon",
]
제대로 내 새로운 Build.gn을 찾아 내 프레임 워크, 사이펀 :
내 Build.gn은 다음과 같습니다 :
if (is_mac) {
loadable_module("Syphon") {
lib_dirs = ["//third_party/Syphon/mac/"]
libs = ["Syphon.framework"]
}
컴파일 작품, 그러나 제가 포함하고있는 Framework의 객체를 사용하려고하면 건물이 실패합니다. 나는 OS X/Xcode에서 이러한 링크 오류에 익숙해졌지만 Ninja/GN에서는 오류를 해결하는 올바른 방법이 확실하지 않습니다.
닌자의 출력 :
주 - 얻어진 링커 인수 적절히 -L/경로 Syphon.framework 보유/행/THIRD_PARTY/사이펀/MAC/그러나 -framework를 사용하는 링커 플래그가 명령이 사이 폰을 찾지 못합니다.
나는 (ldflags와 같은) 다른 Build.gn 명령을 사용하려고 시도했지만 모두 동일한 문제가 발생합니다.
감사합니다.
