Problems when installing QT 4 on Solaris

I have compiled Qt 4.2.1 on Solaris 9 SPARC, no compile error. The command line program such as qmake and uic running ok, but when I runned any gui (designer, qtdemo) program, the program hanged there.
How can do I?

How far does the applications run? Can you run them in a debugging session to get more info? Could it be some sort of problem with your Qt - X11 setup?

I tried to compile qt 4.1.4 on solaris. The problem is as same as Qt 4.2.1, here is my truss output:

There are so man brk!

I don't think Johan meant strace output when he mentioned the debug session...

Compile an application (any application) in debug mode, then run it from within a debugger and step through the code until it hangs. Then you'll know what call causes the trouble.

Try this app:

Code:

---

#include <QApplication>
#include <QPushButton>
 
int main(int argc, char **argv){
  QApplication app(argc, argv);
  QPushButton button;
  button.setText("Falafel");
  button.show();
  return app.exec();
}

---

I used the solaris dbx to debugger this simplest GUI program. but when I type stop in main, then run, then step, the program hanged at QApplication(argc, argv), but the Qt's source code can't step into.
How can do I?

You need to have a debug version of Qt libs.

Finally, my company buyed a Sun Ultra 45 workstation and I installed Solaris 10. At last, I compiled Qt 4.2.2 sucessfully on this machine. Thanks all who has helped me!
