qt4 headers???

all im trying to do is get this to compile:

#include <QApplication>
#include <QLabel>
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel *label = new QLabel("Hello Qt!");
    label->show();
    return app.exec();
}

and here is the errors i get:

/home/nick/Projects/test1/main.cpp|1|error: QApplication: No such file or directory|
/home/nick/Projects/test1/main.cpp|2|error: QLabel: No such file or directory|
/home/nick/Projects/test1/main.cpp||In function 'int main(int, char**)':|

/home/nick/Projects/test1/main.cpp|8|error: 'app' was not declared in this scope|
||=== Build finished: 9 errors, 0 warnings ===|

im assuming its because i dont have the qt4 headers installed but i could be wrong.  how do i install them?

maybe im just setting it up wrong.  is there a special way you have to do it w/ codeblocks?

Re: qt4 headers???

Okay, I googled it for you.

In the same directory as your source code run:

qmake -project; qmake; make

Presto, chango, magico! It works!

Re: qt4 headers???

yeah, i knew how to do it that way.  i guess i should have been more specific.  what exactly do i have to do to get it to compile in Code::Blocks?
