Auto-detect dependencies for make
When qmake generates a make file, I think that it must specify which files depend on others, so that the compiler knows which source files need to be recompiled.
For example, suppose I have
Code:
HEADERS = foo.h bar.h
SOURCES = foo.cpp
and in foo.cpp, I have
Code:
#include "foo.h"
#include "bar.h"
...
If bar.h is modified, then foo.cpp is recompiled upon make.
Here's my question. What if I don't want bar.h to appear in the HEADERS variable? Then foo.cpp will not be recompiled when bar.h is modified :(. Is there a way for me to tell qmake to please look at bar.h --- but don't run moc on it?
Re: Auto-detect dependencies for make
I think I have solved my own problem.
I was mistaken in my previous post.... this has nothing to do with which files appear in the HEADERS variable. It has a lot to do with the DEPENDPATH variable.
But it's not so straightforward. If somebody could write a detailed explanation of the rules for which files get recompiled when, that would be very useful.
The reason that this is important, is that if a header file changes and a library or plugin does not get recompiled, it can lead to an unexpected program crash.
