In the Makefile only the objects are listed. I don't see the rules
for creating the objects. For instance, I would like to know the
place where the compile command to create mac-802-11.o is located
(since I want to add a -Ddegub flag to the cc command).
There isn't an explicit rule to make mac-802_11.o. The makefile falls
back on the
implicit rule to build a .o file from a .cc file, which is
.cc.o:
@rm -f $@
$(CPP) -c $(CFLAGS) $(INCLUDES) -o $@ $*.cc
If you want to set that macro for all files in ns, you should do is
to add -Ddegub
to DEFINE in Makefile.in, re-run configure, and then make, or better
yet, just run
CFLAGS=-Ddegub make
That will set the CFLAGS variable in your system environment before running
make, which will incorporate its value into the CFLAGS string that it uses.
If you only want to set that macro on the one file, add a rule to
Makefile.in similar
to the following:
mac/mac-802_11.o: mac/mac-802_11.cc
@rm -f $@
$(CC) -c $(CFLAGS) -Ddegub $(INCLUDES) -o $@ $*.cc
Then, re-run configure and make.
