[Tinyos-help] Java Makefile

[Muhammad Azhar]

Hi,
   Sorry for the late reply, but I didn't have a chance to use TinyOS for 
the past few days.  Anyway, the 2 structures are not nested structures - 
i.e. they are independent of each other.  Also, I did not add the dash "-" 
sign to the Makefile - in my previous email, the "-" was just to link the 
code to what I was going to say (my apologies for the confusion).
   Actually, I have tried putting a space instead of ";" - but it still 
doesn't work.  Let me just paste the whole Makefile:

COMPONENT=CountAppC
BUILD_EXTRA_DEPS = CountMsg.class BeaconMsg.class

CountMsg.class: CountMsg.java
	javac CountMsg.java

BeaconMsg.class: BeaconMsg.java
	javac BeaconMsg.java

CountMsg.java: C.h
	mig java -target=$(PLATFORM) $(CFLAGS) -java-classname=CountMsg C.h 
countmsg -o $@

BeaconMsg.java: C.h
	mig java -target=$(PLATFORM) $(CFLAGS) -java-classname=BeaconMsg C.h beacon 
-o $@

include $(MAKERULES)

   When I first compiled, it gave me this warning: "warning: Cannot 
determine AM type for beacon (Looking for definition of AM_BEACON)".  I had 
AM_COUNTMSG, but not AM_BEACON initially.  So when I tried running the java 
program for countmsg, the structure for countmsg worked, but when I tried 
running the java program for beacon, there wasn't any output.  Thus, I tried 
inserting AM_BEACON into my C.h file.  I gave it the same value as 
AM_COUNTMSG.  This time round, the warning disappeared, but the output was 
rubbish.  Let me paste some of it:

1172479975200: Message <BeaconMsg>
  [nodeid=0x700]
  [treeDepth=0xd500]

1172479976181: Message <BeaconMsg>
  [nodeid=0x700]
  [treeDepth=0xd600]

1172479977150: Message <BeaconMsg>
  [nodeid=0x700]
  [treeDepth=0xd400]

    The nodeid should be 0x7 and not 0x700.  Also, the treeDepth must always 
be a constant value - in fact it should be 0x1 in this case, as the number 
of hops to the root is only 1 (I have verified this with the countmsg 
structure).  Thus, I tried changing the value of AM_BEACON, but of course, 
as I expected it, running the java program did not generate anything.

    Thank you for your patience.

Regards,
Azhar
