QT: Undefined Reference to KUrlRequester

ESC201 · 09-30-2009, 03:52 PM

Hi all, I am new to the Linux programming world. I am trying to make a simple application in QT Creator with QT 4.5.2 and I am recieveing the error...

Code:

/path/to/file/ui_mainwindow.h:81: undefined reference to `KUrlRequester::KUrlRequester(QWidget*)'

...when trying to compile the program.

The line the error is on (81) is...

Code:

kurlrequester = new KUrlRequester(centralWidget);

I don't know what other info is relevant, so here's some info about my environment. I'm running 64bit Fedora 11 with Gnome 2.26.3. I've installed all the KDE devel packages I can find in the repos.

Any help or a point in the right direction would be awesome. Thank you!

Try this:

Code:

kurlrequester = new KURLRequester(centralWidget);

Thank you for your reply. I now receive...

Code:

/path/to/file/ui_mainwindow.h:81: error: expected type-specifier before ‘KURLRequester’

/path/to/file/ui_mainwindow.h:81: error: cannot convert ‘int*’ to ‘KUrlRequester*’ in assignment

/path/to/file/ui_mainwindow.h:81: error: expected ‘;’ before ‘KURLRequester’

I assume the latter errors are a result of the first error; no harm in posting them however.

Mind posting ui_mainwindow.h in its entirety?

Sure, mind you all this code was generated by Qt Creator.
