Program won't compile since update from Qt5.4 to Qt5.5 | Error in Qt files?

Printable View

This is my old system where my program compiles just fine:

Code:

qt5-base 5.4.1-2
qt5-declarative 5.4.1-2
qt5-doc 5.4.1-2
qt5-graphicaleffects 5.5.0-2
qt5-location 5.4.1-2
qt5-quick1 5.4.1-2
qt5-quickcontrols 5.4.1-2
qt5-script 5.4.1-2
qt5-sensors 5.4.1-2
qt5-svg 5.4.1-2
qt5-tools 5.4.1-2
qt5-translations 5.4.1-2
qt5-webchannel 5.4.1-2
qt5-webkit 5.4.1-2
qt5-xmlpatterns 5.4.1-2
qtchooser 48-1
qtcreator 3.3.2-1

After the update:

Code:

qt5-base 5.5.0-2
qt5-declarative 5.5.0-2
qt5-doc 5.5.0-2
qt5-graphicaleffects 5.5.0-2
qt5-location 5.5.0-2
qt5-quick1 5.5.0-2
qt5-quickcontrols 5.5.0-2
qt5-script 5.5.0-2
qt5-sensors 5.5.0-2
qt5-svg 5.5.0-2
qt5-tools 5.5.0-2
qt5-translations 5.5.0-2
qt5-webchannel 5.5.0-2
qt5-webkit 5.5.0-2
qt5-xmlpatterns 5.5.0-2
qtchooser 48-1
qtcreator 3.5.0-1

This is the error I get:

Code:

It seems like it fails compiling as soon as I include anything Q* in a .cpp file. Even if I remove the statements from src/controller.cpp, a similar error gets thrown in the next file where I include Q*. In it's always "initializer provided for function". A new project compiles fine and I can't pinpoint anything that causes the error in my project. Does anyone have an idea what causes the problem? I'm pretty desperate at this point, any help will be appreciated. I can also upload the source files if the error is too ambiguous.

Re: Program won't compile since update from Qt5.4 to Qt5.5 | Error in Qt files?

What are the first 5-10 lines of src/controller.cpp? If line 1 is an include of controller.h or something else from your sources then that file would be useful to see.

What version of GCC?
Are you doing a clean rebuild without any pre-compiled header lying about?

Re: Program won't compile since update from Qt5.4 to Qt5.5 | Error in Qt files?

controller.cpp

Code:

#include "controller.h"
#include <QObject>
#include <QString>
#include <QVariant>
#include <QVariantList>
#include <QVariantMap>
#include <string>
#include <vector>
#include "controller.h"
#include "itemcontroller.h"
#include "modelcontroller.h"
#include "knowdesk/knowledgeDB.h"
#include "templatecontroller.h"
#include "filecontroller.h"
#include "libs/easylogging++.h"
 
 
void Controller::setQuery(QueryController* q) {
    query = q;
}
 
QueryController* Controller::getQuery() {
    return query;
}
.
.
.

controller.h

Code:

#ifndef CONTROLLER_H
#define CONTROLLER_H
 
class QueryController;
class FileController;
class ModelController;
class TemplateController;
class ItemController;
class KnowledgeDB;
 
class Controller {
  public:
    void setQuery(QueryController*);
    QueryController* getQuery();
 
    void setFile(FileController*);
    FileController* getFile();
 
    void setModel(ModelController*);
    ModelController* getModel();
 
    void setTemplate(TemplateController*);
    TemplateController* getTemplate();
 
    void setItem(ItemController*);
    ItemController* getItem();
 
    void setDB(KnowledgeDB*);
    KnowledgeDB* getDB();
  private:
    QueryController* query;
    FileController* file;
    ModelController* model;
    TemplateController* template_;
    ItemController* item;
    KnowledgeDB* db;
};
 
#endif // CONTROLLER_H

I don't actually use any of the Q* in controller.cpp. If I remove the #include <Q*> statements, this error will be thrown in the next Header File that attempts to include Q*, itemcontroller.h:

I have gcc version 5.2.0 and the same error appears after I delete all build files, rerun qmake and rebuild.

I went back in my repo and found that the point where this compilation error first appears is when I change

Code:

QApplication app(argc, argv);
QQmlEngine engine;

Code:

QtQuickControlsApplication app(argc, argv);
QQmlApplicationEngine engine;

But even after changing this in back in the main.cpp file, or even commenting everything there out, it fails much at other files. So I'm not sure if this relates.

Here are the source files: http://ge.tt/13W34MP2/v/0
You need SQLite and QtCreator as I haven't configured it for static build yet.
I can offer to 0.08BTC (around 17â‚¬) for anyone who can help me.
