error when compiling with qmake and make

[rasputin]

hei
I am trying a simple helloworld program to test qt4, and it seems like I have wrong library files or something

Here's the program I try to compile:

** This file is provided AS IS with NO WARRANTY OF ANY KIND, INCLUDING THE
** WARRANTY OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
**
************************************************** **************************/

#include <QApplication>
#include <QPushButton>

int main(int argc, char *argv&#91;])
{
QApplication app(argc, argv);

QPushButton hello("Hello world!");
hello.resize(100, 30);

hello.show();
return app.exec();
}

And here's the last lines of the result of the compiling:

In file included from /usr/include/qt4/QtGui/qpolygon.h:47,

/usr/include/qt4/QtCore/qvector.h:253: error: ‘ptrdiff_t’ does not name a type
make: *** [main.o] Error 1

As usual I use qmake -project
then qmake
and then make.

It did work in other distros.

Re: error when compiling with qmake and make

Looks to me like qt 4 is not installed correctly. How did you install it?
You may have more luck with this question in qt related forums like http://www.qtcentre.org/forum/ Good help there.
Good luck.
