Dependencies

[Uri Shkolnik]

Hi,

I'm quite novice to Make :-( ,  and I'm using 
1) GNU Make 3.81 i386-pc-mingw32 
and 
2) GNU Make version 3.79 (RedHat v9)

My problem is that when modifying (or just "touch") a source file (*.c) the 
Make detects it and recompiles that specific file. (without re-compiling the 
rest of the project, and that's just fine)

BUT, when modifying an included header file (*.h) the Make does not detect it 
and that causes a major problem (I need to forcedly rebuild the entire project).

The relevant part of my makefile is attached below. Any assist will be more 
than welcome.


Best Regards,

Uri
