      Hi everyone,

      I have a problem with Qt Creator not seeing include files when using pkgconfig. Everything builds and runs fine, but the text editor does not see the include files and hence does not autocomplete.

      My setup is:

      Linux 3.6.10-1-ARCH #1 SMP PREEMPT Tue Dec 11 09:40:17 CET 2012 x86_64 GNU/Linux

      Qt Creator 2.6.1
      Based on Qt 4.8.4 (64 bit)

      Example:

      gst.pro
      @QT += core gui

      greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

      TARGET = gst
      TEMPLATE = app

      SOURCES += main.cpp
      widget.cpp

      HEADERS += widget.h

      unix:!macx {

      INCLUDEPATH += /usr/include/gstreamer-0.10

      CONFIG += link_pkgconfig
      PKGCONFIG += gstreamer-interfaces-0.10
      

      }@

      main.cpp
      @#include "widget.h"
      #include <QApplication>

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

      return a.exec&#40;&#41;;
      

      }@

      widget.h
      @#ifndef WIDGET_H
      #define WIDGET_H

      #include <gst/gst.h>
      #include <gst/interfaces/xoverlay.h>
      #include <QWidget>

      class Widget : public QWidget
      {
      Q_OBJECT

      public:
      explicit Widget(QWidget *parent = 0);
      ~Widget();

      private:
      GstElement *m_pipeline;
      GstElement *m_src;
      GstElement *m_sink;
      };

      #endif // WIDGET_H@

      widget.cpp
      @#include "widget.h"

      Widget::Widget(QWidget *parent) :
      QWidget(parent)
      {
      gst_init(NULL, NULL);

      m_pipeline = gst_pipeline_new("pipeline");
      m_src = gst_element_factory_make("videotestsrc", "src");
      m_sink = gst_element_factory_make ("xvimagesink", "vSink");
      
      gst_bin_add_many(GST_BIN(m_pipeline), m_src, m_sink, NULL);
      gst_element_link_many(m_src, m_sink, NULL);
      
      gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(m_sink), this->winId());
      
      gst_element_set_state (m_pipeline, GST_STATE_PLAYING);
      

      }

      Widget::~Widget()
      {
      gst_object_unref(m_pipeline);
      }@

      Sorry for the long post. I don't know if this is a correct place to ask.
      I welcome any suggestions.

      Thanks,
