CMake

Question

kullanarak Qt moc hatası

Qt ile GUI oluşturan ve CMake kullanarak makefiles oluşturma bir OpenCV uygulama yazmaya çalışıyorum.

This file was generated using the moc from 5.2.1. It cannot be used with the include files from this version of Qt. (The moc has changed too much.)

Tamam: Ben sorun ben make komutu çalıştırmak çalıştığınızda hata alıyorum olmasıdır. Bu yüzden moc'u qt4 yerine qt4'ten kullanmaya çalışmalıyım (hem qt4 hem de qt5 yüklü). Tabii ki,ve /usr/bin/moc'a sahip olduğumdan, tek yapmam gereken şey invoke sudo update-alternatives --config moc, ama tek alacağım update-alternatives: error: no alternatives for moc.

Kaynağım ve başlık dosyaları şunlardır: Hmmm ...

nedenle, sorunun ya qt ya benim CMakeLists.txt sürümüyle olduğunu düşünüyorum, işte bunun için kullanılan koddur Şu an çok boş ama onları da göndereceğim. Kim bilir, belki de hata var.

main.cpp:

#include <iostream> 
#include "VigilWidget.h" 
//#include <QApplication> 

int main(int argc, char *argv[]) { 
    QApplication app(argc, argv); 
    std::cout << "Testing"; 
    VigilWidget vigil; 
    vigil.show(); 
} 

VigilWidget.cpp:

#include "VigilWidget.h" 

VigilWidget::VigilWidget(QWidget *parent) 
    : QWidget(parent) 
{ 
    ui.setupUi(this); 
} 

VigilWidget.h: Neyse

, iki gün bu almanın en iyi parçası geçirdim uzak ve gerçekten bazı yardım gerçekten takdir ediyorum! Çok teşekkürler! Qt5 için

Yapılandırma:

set(QT_VERSION_REQ "5.2") 
find_package(Qt5Core ${QT_VERSION_REQ} REQUIRED) 
find_package(Qt5Quick ${QT_VERSION_REQ} REQUIRED) 
find_package(Qt5Widgets ${QT_VERSION_REQ} REQUIRED) 
set(CMAKE_AUTOMOC ON) 

add_executable(${PROJECT_NAME} ${SOURCES}) 
target_link_libraries(${PROJECT_NAME} 
    Qt5::Core 
    Qt5::Quick 
    Qt5::Widgets  
) 

Ve iyi kullanılması QtQuick yerine QWidgets mümkünse.
