[Qt-interest] Qt 4.6.3 and Mingw compiler strange behaviour

  First, just an observation: As I think you realize, this problem
  has nothing to do with the compiler per se; your problem seems
  to be that your makefile isn't correctly aware of all of the
  dependencies in your project. And qmake, of course, creates
  makefiles that are driven by the data in your .pro/.pri "project" files.

  So, when was the last time you ran "qmake -project" (or manually
  edited your .pro/.pri files)? Was it before you added the problematic
  header file to your project?

Hi all.
I'm using Qt sdk Win opensource 2010.04.
I'm observing a strange behaviour of the compiler and I don't understand the cause.

When I modify a header file in my Qt project the g++ compiler doesn't recompile all the files that include it. If I want to correctly build the program I must clean the whole project each time (and this is very annoying).


This seems to be a problem of the makefile that is generated by the qmake.
I tried with different computers and different Qt versions but I got the same results.


Did someone notice the same behavior? Is there a solution?

Thanks
  Davide
