KFileDialog undefined reference

[kandalf]

Hi guys!
I'm starting to program with KDE. I have some experience on C++ and Qt and now, after a long time away from these tools, I'd like to start programming to this lovely desktop.
I started with a tutorial from Antonio Larrosa's site and I got stucked when I got this error:

MainWindow.o(.text+0x711): In function `MainWindow::fileOpen()':
/home/leonardo/development/console/kde/tutorial/src/MainWindow.cpp:67: undefined reference to `KFileDialog::getOpenURL(QString const&, QString const&, QWidget*, QString

I have included <kfiledialog.h>
Does anybody know why this can be hapenning?

Thanx a lot in advance.

Maybe you don't link your program with appropriate libraries?

[kandalf]

Maybe... I'm using KDevelop 3.5.2 I think it takes care of all that stuff.
Is kio the library needed?
I tried to modify the project options adding -lkio to the LDFLAGS on project options menu buth after that I got the message

C compiler cannot create executables

And taking a look to the Makefile generated in the src subdir I found this line:

LIB_KIO = -lkio

What made me think that was using this lib but now, after your post, I found in KDevelop's output that -lkio is not mentioned anywhere. This is the final output of compile try

/home/leonardo/development/console/kde/tutorial/src/MainWindow.cpp:67: undefined reference to `KFileDialog::getOpenURL(QString const&, QString const&, QWidget*, QString const&)'
collect2: ld returned 1 exit status

Any ideas what library do I need and how can I add it to KDevelop?

Thanx a lot again and sorry for these newbie questions.

Ok, I have the first approach to the solution of this problem.
It is so not the best, but it works.
I had to add -lkio, by hand, to the LDFLAGS line in the Makefile built in srcs after running configure script in the console.
The result LDFLAGS line is:

LDFLAGS = -lkio

LDFLAGS = -lkio

To copy to clipboard, switch view to plain text mode 

Now the question is how to automate this task for KDevelop environment.
Is it a bug in KDevelop or am I doing something wrong?

Cheers!

I'm don't know much about autotools, but it seems that they add libkio all by themselves.

I thought so, but aparently they didn't this time.
It might be a KDevelop's or Kandalf's error
Maybe I'm not properly setting project's configuration.

Do you work with KDevelop?

Do you work with KDevelop?

Yes, but unfortunately I don't use autotools.

[kandalf]

Nevermind, I found it. In the right side of the KDevelop's window I have a tab with Automake settings.
From there I can modify what I want.

Thanx a lot for your time anyways.

Cheers.
