Probleme beim Umstieg von qmake auf cmake

msauer75

Hallo zusammen,

ich wollte jetzt mal ein Qt Projekt von qmake auf cmake umstellen. Leider bekomme ich beim erstellen einer Library immer nur Fehler.

Der Inhalt der qmake.pro:

Ein Aufruf von make in dem qmake Projekt gibt keinen Fehler und das Programm wird fehlerfrei compiliert.
Hat einer von Euch eine Idee woran das Problem liegen könnte?

Danke für Eure Hilfe.

@msauer75 said in Probleme beim Umstieg von qmake auf cmake:

include_directories(${Qt5

Das ist unnötig.

file(GLOB

Das sollte nicht genutzt werden. Die sourcen bitte ordentlich einzeln aufführen.

${Qt5Widgets_EXECUTABLE_COMPILE_FLAGS}

Was soll das? Unnötig.

-pipe -O2

dito

controllers::NavigationController

in welcher Source-Datei ist das? Ist es eine statische oder dynamische lib oder ist es direkt mit in diesem Projekt?
Wenn dynamische lib - wird die Klasse korrekt exportiert?

msauer75

@Christian-Ehrlicher

Danke Dir schon mal für deine Tips. Die unnötigen Punkte habe ich aus diversen Infos / Tutorials wo die das so gemacht haben.

Bezgl.

controllers::NavigationController

Die Klasse ist in einem include File in der Library gc-lib:

namespace controllers {

class GCLIBSHARED_EXPORT NavigationController : public QObject
{
    Q_OBJECT

public:
    explicit NavigationController(QObject* _Parent = nullptr) : QObject(_Parent) {}

signals:
    void goDashboardView();
    void goGcListView();
    void goGcEditView();
    void goGcMapView();
    void goGcSearchView();
    void goGcDescViewShort();
    void goGcDescViewLong();
    void goGcDescViewHint();
    void goAdminView();
    void goWpEditView();
    void goWpNoteView();
    void goWpMapView();
    void goPqImportFileOpenView();
    void goPqImportBackView();
    void goGsakListView();
    void goGcDescView();
};

Die einzelnen FUnktionen sind Signale, die aus meiner masterview.qml kommen:

    Connections {
        target: masterController.ui_navctrl
        onGoDashboardView: contentFrame.replace("qrc:/views/DashboardView.qml")
        onGoGcListView: contentFrame.replace("qrc:/views/GcListView.qml")
        onGoGcEditView: contentFrame.replace("qrc:/views/GcEditView.qml", {selectedCache: masterController.ui_cache})
        onGoGcMapView: contentFrame.push("qrc:/views/GcMapView.qml", {selectedCache: masterController.ui_cache})
        onGoGcSearchView: contentFrame.replace("qrc:/views/GcSearchView.qml")
        onGoGcDescViewLong: contentFrame.replace("qrc:/views/GcDescView.qml", {dispText: masterController.ui_cache.ui_desclang, headerText1: "Beschreibung lang"})
        onGoGcDescViewShort: contentFrame.replace("qrc:/views/GcDescView.qml", {dispText: masterController.ui_cache.ui_desckurz, headerText1: "Beschreibung kurz"})
        // onGoGcDescViewHint: contentFrame.replace("qrc:/views/GcDescView.qml", {dispText: masterController.ui_cache.ui_hint, headerText1: "Hinweis"})
        onGoGcDescView: contentFrame.push("qrc:/views/GsakDescView.qml", {cacheItem: masterController.ui_cache})
        onGoAdminView: contentFrame.replace("qrc:/views/AdminView.qml")
        onGoWpEditView: contentFrame.replace("qrc:/views/WpListView.qml")
        onGoWpNoteView: contentFrame.replace("qrc:/views/WpNoteView.qml")
        onGoWpMapView: contentFrame.replace("qrc:/views/WpMapView.qml", {selectedCache: masterController.ui_cache, wpListe: masterController.ui_wpliste})
        onGoPqImportFileOpenView: contentFrame.replace("qrc:/views/PqImportView.qml", {importDone: false, pqImport: masterController.ui_pqimport})
        onGoPqImportBackView: contentFrame.replace("qrc:/views/PqImportView.qml", {importDone: true, pqImport: masterController.ui_pqimport})
        onGoGsakListView: contentFrame.replace("qrc:/views/GsakListView.qml", {onViewLoad: masterController.ui_gsak.onViewLoad()})
    }

@msauer75 said in Probleme beim Umstieg von qmake auf cmake:

GCLIBSHARED_EXPORT

Wird dies korrekt gesetzt wenn die lib gebaut wird bzw. genutzt wird?
Ist die Lib statisch oder dynamisch.

Die unnötigen Punkte habe ich aus diversen Infos / Tutorials wo die das so gemacht haben.

Schlechte Beispiele gewählt :)

@Christian-Ehrlicher

D.h. die sourcen einzeln in add_executable?

@msauer75 said in Probleme beim Umstieg von qmake auf cmake:

SET(SOURCES
eins.cpp
eins.h
zwei.cpp
...
)

add_executable(blub ${SOURCES})

@Christian-Ehrlicher

Nachdem ich jetzt alle Resourcen (*.cpp, *.h, *.qrc) einzelnen in die jeweiligen CMakeLists.txt Dateien hinzugefügt habe kann ich das ganze Projekt compilieren und die Anwendung auch starten.

Danke dir für deine Hilfe.
