Re: Makefile

[xueyue]

Dear Marcus, 
I was not able to solve the problem with your following suggestion. This
was due to that I still can not totally understand how to modify
respective Makefiles. However, I did 
solve the problem with my own awkward but successful way. 
First, in each subdirectory where some classes are defined, there is a
Makefile, for example, the Makefile in modelSwarm/node directroy looks
like:

====================
ifeq ($(SWARMHOME),)
SWARMHOME=/usr
endif
APPLICATION=test

OBJECTS=main.o MATSNodeItem.o MATSLinkItem.o
include $(SWARMHOME)/etc/swarm/Makefile.appl
main.o: main.m
MATSNodeItem.o: MATSNodeItem.h MATSNodeItem.m
MATSLinkItem.o: MATSLinkItem.h MATSNodeItem.h MATSLinkItem.m
======================= 
here main.m is just the main programme doing nothing. (without
it,  make will not work).  

then in a (super) directory, there is a Makefile:
=============================================================
ifeq ($(SWARMHOME),)
SWARMHOME=/usr
endif
SUBDIRS = modelSwarm/node modelSwarm/traveller modelSwarm
APPLICATION=mats
OBJECTS=main.o 
headers:
                 for i in $(SUBDIRS) ; do $(MAKE) -C $$i;  done         

=============================================================

then, when make is executed in this superdirectory, all 
Makefiles' command in directories in SUBDIRS will be executed, i.e.,
make will be successfully executed in each of the directories in
SUBDIRS.

I have been able to go round  the problem, and the solution 
is good enough for my project. But I think this problem should 
not have happened if files in /usr/etc/swarm/, Makefile.lib,
Makefile.rules, and Makefile.common, etc., are correct.  Why
I am saying so? Let us look again at Makefile I sent before:

=============Makefile=======================
ifeq ($(SWARMHOME),)
SWARMHOME=/usr
endif
APPLICATION=mats
OBJECTS=main.o traveller/Traveller.o clock/CurrentTime.o ModelSwarm.o
node/MATSNodeItem.o node/MATSLinkItem.o router/RouteFinder.o
include $(SWARMHOME)/etc/swarm/Makefile.appl
main.o: main.m ModelSwarm.h
router/RouteFinder.o: router/RouteFinder.h router/RouteFinder.m
==============End====================================

To  our general understanding, make will produce two  object
files: main.o and router/RouterFinder.o. However, 
When make is executed, we can see the process of compiling, and the
following command will be executed:
egcs -c -Wno-import -Wno-protocol -g -O2 -fno-inline -D_GNU_SOURCE
-I/usr/include/swarm router/RouterFinder.m

The only problem is that after RouterFinder.m is compiled, 
the result can not be written in router/RouterFinder.o!!!

That is why I think some files in /usr/etc/swarm/ may have 
some minor faults. If so, I think they may need to be modified.

Cheers!
