maemo 5

Installing maemo 5 (freemantle, see codenames) for N900 (maemo 5 does not run on the N810) in a SUSE Linux 11.2 x32 virtual machine resulted in 

Processing was halted because there were too many errors.

So trying SUSE 11.1 (where maemo 4 worked): 

root@i386 # useradd -m scratchboxuser
root@i386 # passwd scratchboxuser
root@i386 # wget http://repository.maemo.org/stable/fremantle/maemo-scratchbox-install_5.0.sh
root@i386 # chmod 777 maemo-scratchbox-install_5.0.sh
root@i386 # ./maemo-scratchbox-install_5.0.sh -s /scratchbox
root@i386 # /scratchbox/sbin/sbox_adduser scratchboxuser
root@i386 # su - scratchboxuser
scratchboxuser@i386 $ wget http://repository.maemo.org/stable/fremantle/maemo-sdk-install_5.0.sh
scratchboxuser@i386 $ sh maemo-sdk-install_5.0.sh

main.cpp 

#include <QApplication>
#include <QPushButton>
int main(int argc, char ** argv)
{
  QApplication qa(argc,argv);
  QPushButton* qp=new QPushButton("hello world");
  qp->show();
  return qa.exec();
}

Build and run it: 

export DISPLAY=:4
qmake -project && qmake && make && ./qttest
