hi
i'm trying to do the exercise of lesson 7 of tinyos tutorial.
i've got a bug in step two which consist of In SimpleCmdM.nc, to
initialize the sounder and add a new command action that will turn the
sounder on and off.
i've joined to the mail the file simplecmdM.nc that i modified.
changes were made at line 64, 80, 124-130 and 148.
when i compile simplecmd i got this error message:
$ make install mica2
compiling Bcast to a mica2 binary
ncc -o build/mica2/main.exe -Os -board=micasb -target=mica2
-DCC1K_DEF_FREQ=9164
00000 -Wall -Wshadow -DDEF_TOS_AM_GROUP=0x7d -Wnesc-all
-finline-limit=100000 -f
nesc-cfile=build/mica2/app.c Bcast.nc -lm
SimpleCmd.nc:56: cannot find `Sounder'
make: *** [build/mica2/main.exe] Error 1
i'm trying to fix the bug. help me please.

* SimpleCmdM is a tiny OS application module.
* This module demonstrates a simple command interpreter for the TinyOS
* tutorial. The module receives a command message from the radio, which
* is passed to the ProcessCmd interface for processing. A task is posted
* to process the command. The command packet contains a one-byte
* 'action' field specifying which action to take; as a simple version,
* this module can only interpret the follwoing commands:
* Led_on (action = 1), Led_off (2), radio_quieter (3), and radio_louder
(4).
*
* This module also implements the ProcessCmd interface.
