change in header file -- when to recompile in c

Question

In C, I have a header file file1_0.h which is included by only file1.h and file1.c.

file1.h is included by many other files say, file2.c, file3.c and file4.c

If I make any change in file1_0.h I know that I need to re-compile file1.c but do I also need to recompile file2.c, file3.c and file4.c ?

Create a makefile with dependency rules. – Fiddling Bits Aug 08 '14 at 01:59 — Fiddling Bits, Aug 08 '14 at 01:59

Yes.

All your other files depend on file1_0.h since file1.h depends on it and all the others depend on file1.h. So you need to recompile "to be safe".
