Ошибка при включении файлов заголовков qgis

Question

Я работаю над созданием простого приложения qt с использованием QGIS API для загрузки простого файла карты или формы. Но в настоящее время я застрял, включая файлы заголовков qgis. Код очень прост:

// 
// QGIS Includes 
// 
#include <qgis/qgsapplication.h> 
// 
// Qt Includes 
// 
#include <QString> 
#include <QApplication> 
#include <QWidget> 
int main(int argc, char ** argv) 
{ 
    // Start the Application 
    QgsApplication app(argc, argv, true); 
    QApplication a(argc, argv); 
    return app.exec(); 
} 

Я просто пытаюсь включить qgsapplication на первом этапе. Но это показывает, так много ошибок (38 ошибок в окне вопросов), а вот выход компиляции:

Может кто-нибудь дать мне предложение? Моя среда - OpenSUSE 13.2, QT 4.8.6, QGIS 2.8.

Answer 1

Я не знаю QGis, но, похоже, вы должны #include заголовки QGis после QT.

Answer 2

Попробуйте с
