QT Program debug,GDB on Linux

[darpan]

Hi,
I am new to qt linux. I want to know about the ways of debuging qt program in linux.
(1) I go through the GDB debugger on linux.
I have following questions:
To Debug using GDB, with which option i have to compile the qt program on terminal.
how i can put a break point in qt program function.
(2) if i take my qt project in kdevelop , how can i set environment variable in kdevelop to build the qt program succesfully.

Thanks and Regards

To Debug using GDB, with which option i have to compile the qt program on terminal.

The minimum is to use "-g" option. If you use qmake, add "CONFIG += debug" to your .pro file.

how i can put a break point in qt program function.
