silly undefined refrence to main

[quickNitin]

Well i need more help!!!

I am designign a form in Qt4.1.2 dsigner.
I inherit form-class and put some more features. In the same file i am defining main() and naming this file as main.cpp;

i went through copy book stpes for compilation . It results in link time error

g++ -Wl,-rpath,/usr/local/Trolltech/Qt-4.1.2/lib -o Info -L/usr/local/Trolltech/Qt-4.1.2/lib -lQtGui_debug -L/home/qt-x11-opensource-src-4.1.2/lib -L/usr/X11R6/lib -lpng -lSM -lICE -lXi -lXrender -lXrandr -lXcursor -lXinerama -lfreetype -lfontconfig -lXext -lX11 -lQtCore_debug -lz -lm -ldl -lpthread
/usr/lib/gcc/i386-redhat-linux/4.0.0/../../../crt1.o(.text+0x18): In function `_start':
: undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [Info] Error 1

pro file also look good.
Is there a web link talking about all such silly novice issues.

I have done some modification to make my code work , its doing . What iremeber is i was inheriting class generated by uic and puting sme more operations. then typical main where this error was resulting.

i found , even if i am creating a dialog in designer it still do not inherit from QDialog class. Ihave to make a object to pass to setupUi(). Is it normal.
Also i am following following steps for compilation
1. qmake -project
2. qmake
3. make

but qmake donot detects ui file and convert to equivalent .h but it shows entry for it in pro file.

The class generated by uic is not a widget. It's just a class for creating the designed ui for the given widget. I strongly suggest you to read this doc: Using a Component in Your Application
