- Subject: Dependency generation with -MM
I want to implement an automated system that generates dependency information
for my project's sources. I've used the standard technique:
OBJS=a.o b.o ../../directory/c.o
/bin/rm -f depend
for i in $(OBJS); do \
$(CPP) -MM $(CPPFLAGS) `echo $$i | sed "s/\(.*\)\\.o$$/\1.cpp/"` >> depend;\
ifeq (depend,$(wildcard depend))
The problem with this approach is that the following line:
g++ -MM ../../directory/c.cpp
outputs the following make rule:
I would like it to output the rule as:
Is there any way to do this with a g++ switch (I couldn't find one in the
manual), or do I have to write my own utility to perform that conversion?
Thanks in advance.
