gstreamermm 및 Qt 컴파일 오류

Qt를 처음 사용하고 Qt로 기본 gstreamermm 예제를 실행하려고합니다. qt의 main.cpp에 gstreamermm.h를 포함 시키면 컴파일 오류가 발생합니다. 나는 그 오류가 무엇을 말하는지 이해할 수 없다. 이 예제에서는 Qt 생성자를 사용하고 있습니다.gstreamermm 및 Qt 컴파일 오류

#include <QApplication> 
#include <gstreamermm.h> 

int main(int argc, char *argv[]) 
{ 
    QApplication a(argc, argv); 
    MainWindow w; 
    w.show(); 

    return a.exec(); 
}

정말 감사 위 대한 컴파일 오류를

Qt가 Q_FOREACH의 줄임말로 foreach 매크로를 정의하기 때문에 오류가 나타납니다. 이는 몇 가지 gstreamermm 클래스에서 foreach 메소드 선언과 충돌합니다.

  1. 이 Qt는 프로젝트 파일에 CONFIG += no_keywords 줄을 추가

    이 문제를 방지 할 수있는 몇 가지 방법이 있습니다. 예를 들어 다음과 같은 Qt 전용 키워드를 사용할 수 없습니다. signals 및 slots. QtCreator에 의해 자동 생성 되었기 때문에 이미 사용하고 있다면 Q_SIGNALS 및 Q_SLOTS 매크로로 대체 할 수 있습니다.

  2. gstreamermm.h을 Qt 헤더 앞에 넣어서 헤더 포함 순서를 변경하십시오.

  3. gstreamermm.h을 포함하기 전에 Qt 헤더를 포함시킨 후 #undef foreach을 넣습니다.

2와 3은 헤더 포함의 순서가 잘 작성된 라이브러리를 사용하는 잘 작성된 응용 프로그램에서 문제가되지해야 하나 어떤 #define s 또는 #undef Ines는 소개 안하기 때문에, 훨씬 덜 우아한 솔루션있는 사용 된 라이브러리의 문서에 명시 적으로 명시되지 않는 한 포함 된 선언에 영향을줍니다. ../untitled/mainwindow.h:18:9 : 오류 : 예상 이제

맞아요 -'no_keywords' 수 있습니다 기존 코드를 해독하십시오. 이것을 피하려면'slots'을'Q_SLOTS'로 변경하십시오. 이 발언을 포함하도록 답변을 업데이트했습니다. –

그게 효과가! 감사. 그러나 나는 그 문제가 무엇인지를 정말로 이해할 수 없다. – sap
