ok I am giving qt a try when it comes to programing.. but for the life of me I can not get anything to compile..

here is my first program 

#include <qapplication.h>
#include <qpushbutton.h>

int main( int argc, char **argv )
{

QApplication a( argc, argv );
QPushButton hello( "Hello world!", 0 );
hello.resize( 100, 30 );
a.setMainWidget( &hello );
hello.show();
return a.exec();

}

ok this is why I post this stuff. I alwyas find my answer 10 min later.

my make file created by qmake is incorrect.. I also needed to create a env variable called QTDIR which pointed to /usr/qt/3

and add a linking -lqt

along with my lib was wrong.. qmake said it was in /usr/X11R6/lib but it was in /usr/qt/3/lib

this command showed me what to do

g++ -Wall -I/usr/qt/3/include -L/usr/qt/3/lib test.cpp -o hello -lqt
