[Tinyos-help] Passing Arguments at compile time

[Darren Bishop]

I have explained how to set source and destination nodes.

What you now need to do is use conditional branching in your makefile:

ifdef SRC
PFLAGS += -DSRC_NODE=$(SRC)
else
PFLAGS += -DSRC_NODE=0
endif

Invoke make like so:

prompt$ SRC=2 make pc
