Qt with eclipse C++
-
Hi to all, im using C++ eclipse and make a simple GUI on Qt (Im using linux Tumbleweed). The GUI is a simple window with 2 buttons . I use the UIC file to generate a cpp file (header file) and then import that file into eclipse, also I added the Qt include folder into eclipse library path. Till here no problems, when I try to display the GUI on eclipse using this code inside main :
Ui::MainWindow *dialog; QMainWindow w; dialog = new Ui::MainWindow(); dialog->setupUi(&w); w.show();this error is shown:
undefined reference to `QMainWindow::QMainWindow(QWidget*, QFlagsQt::WindowType)'
I have this includes :
#include "QtWidgets/QApplication"
#include "QtWidgets/QDialog"Im new in the Qt world. Also is possible to get a tutorial about eclipse C++ and Qt?
Thanks in advance

I add Qt5Core Qt5Gui and Qt5Widgets and it works.

Do you mean to include path?
The error message means that you're not linking against Qt libs. -
hi jsulm,
you are right, I add the Qt include folder to eclipse include path. Looking Qt library folder, do I need to add all those library to eclipse library?
Thanks

When last I looked at the Qt plugin for eclipse it was hopelessly broken. At the time eclipse had a lot of problems parsing the Qt framework include files and MOC system for code checking. Are you using the plugin, or just using eclipse as an editor?
