Hello,
I have a problem with dependencies across directories. Let me describe it:
We have the following directory structure:
/tmp/makefiletest/
makefile.inc
A/
a.h
a1.h
makefile
B/
b.cc
makefile
makefile.inc
---
VPATH /tmp/makefiletest
A/makefile
---
a.h: a1.h
touch $@
B/makefile
---
b.o: A/a.h
/tmp/makefiletest/B> make b.o
The goal of this test if to have b.cc recompiled if a.h or a1.h changes.
If a.h changes, it works, but if a1.h changes it does not work. I am
aware that the A/makefile file is not read, and so the dependency
between a1.h and a.h is not discovered.
We follow this makefile pattern for our codebase, and only recently I
discovered this "bug" in our pattern. Is there an easy way to fix it
without braking everything?
Thanks,
Ray
