undefined reference to..

I don't know if here's the right place to ask but, since I use only Linux I whant full compatibillity with KDE and I don't know what am I doning wrong:

#include <kfiledialog.h>

KFileDialog* dia = new KFileDialog ("/", "*", this, "dia",false);

*** error***

undefined reference to `KFileDialog::KFileDialog[in-charge](QString const&, QString const&, QWidget*, char const*, bool)'

Some tips for full compatibillity with KDE are allso welcome :)

thank you

You have to link the appropriate kde libs.
For KFileDialog, it's -lkio if I remember correctly.

Go to the "Automake manager"-tab, right-click on your project name in the list, choose "Options". Then switch to the tab "Libraries", click on the "Add"-button and either type "-lkio" or "$(LIB_KIO)".

The library is usually named like the respective section in the API docs.

For example if a class is documented in kio, the lib is libkio, which means linker directive -lkio or variable $(LIB_KIO)

if just dont find the lib who belong to any class or function in the api, as anda_skoa explained, this are the most common link directives:


-lkdecore
-lkdeui

and more,.. just try if you cannot find them
