How to use part of one project in other project?

[Draqun]

Hi.

This is my first real app with QT and QtCreator. Can someone tell me how in QtCreator 3.5.1 in Ubuntu use part of one project into another? Directory three looks that

Project/
    my-qt-project/
        inc/
           #some headers
        src/
            #some sources
        main.cpp
    my-qt-project-gui/
        main.cpp
        #other sources

my-qt-project is a console version of app. The second one is version with GUI which use a lot of code from the first one, but I cannot import headers and compile it. In project build settings I set my-qt-project as a dependency.

There a simple way to share part of one project with another? I tried use https://wiki.qt.io/SUBDIRS_-_handling_dependencies but it does not work.
http://stackoverflow.com/questions/16876690/qt-creator-how-do-i-add-one-c-project-to-another - I was here too.

Best regards.

Hi and welcome to devnet,

The subdirs template is the right thing to use. Usually you would create one or more library projects with the common code and then one project per application.

What did you try exactly ? Can you share your .pro files ?

Basic project

CONFIG += c++11
QMAKE_CXXFLAGS += -std=c++11
QT += sql
QT -= gui
TEMPLATE = app
TARGET = qt-simple-notifier
INCLUDEPATH += . \
                include

# Input
SOURCES += main.cpp \
    src/QtSimpleNotifier/DatabaseManager.cpp

DISTFILES += \
    LICENSE \
    README.md

HEADERS += \
    inc/QtSimpleNotifier/DatabaseManager.h

Project with GUI

template = subdirs
SUBDIRS += ../qt-simple-notifier

#include(../qt-simple-notifier/qt-simple-notifier/inc/*)
#include(../qt-simple-notifier/qt-simple-notifier/src/*)

INCLUDEPATH += ../qt-simple-notifier
CONFIG += c++11
QMAKE_CXXFLAGS += -std=c++11
QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = qt-simple-notifier-gui
TEMPLATE = app


SOURCES += main.cpp \
        mainwindow.cpp \
    addreminderdialog.cpp

HEADERS += mainwindow.h \
    addreminderdialog.h

FORMS    += mainwindow.ui \
    addreminderdialog.ui

RESOURCES += \
    resources.qrc

DISTFILES += \
    LICENSE \
    README.md

My *.pro files.

I don;t want create library project with shared code. I just want include and compile a few class in project with GUI from project with console interface.

Best regards.

Even without a library, your design is wrong.

You should have something like:

-- MyProject
---- cli_project
---- gui_project

With MyProject being the subdirs template pointing to the other two. Then in your GUI project you'll use SOURCES += ../cli_project/file_you_want.cpp etc.

That was more complicated than I thought.
Thanks for help. Now all work fine.

Best regards.

Why are you adding the src folder to INCLUDEPATH?
