Hi,
Open the attached file, look at the dependecy file for my derived.cpp. It depends just on myderived.h.
Now add a #include <stdio.h> to myderived.cpp and compile. The .depend file is not updated.
Close the project and re-open it and change something in myderived.h and compile. The .depend will be correctly updated.
This means (I may be wrong) that in the middle of a session the .depend file can be not consistent
with the source.
See my previoues post for OS and version.
