QDoubleValidator porting to Linux issue

[mqt]

When we try to port a Qt4 code from windows to linux, we are getting following error
error: no matching function for call to ?QDoubleValidator::QDoubleValidator()?
It is working fine in windows. Any ideas?

Does this work?

#include <QDoubleValidator>
 
int main() {
  QDoubleValidator v;
  return 0;  
}

#include <QDoubleValidator>

int main() {
  QDoubleValidator v;
  return 0;  
}

QDoubleValidator v;
has not worked. But QDoubleValidator *v=new QDoubleValidator (0); worked
Thanks

What do you mean that it has "not worked"?
