Hi Gary, Phil & other folks
First up, Phil, thanks a lot for your explanation of the ncc call
chain
I am still not able to compile the Blink....I have tried to
organize all my doubts & whatever i have attempted, to do to get it
to work, in the following 5 queries :
(1) As suggested by Phil above, i tried compiling the simple 5-line
code he had mentioned.
I created a directory in /opt/tinyos-2.x/apps & created a file
phil.c in it containing the 5-line code.
Now if i try to compile this with just "avr-gcc" it does not
succeed, but if i use the command avr-gcc-3.4.3 it compiles ok.
Am i correct in assuming, & as hinted by Phil, that the problem is
that avr-gcc internally invokes avr-gcc-3.4.3 but is not pointing
correctly to it & hence efforts to compile using avr-gcc fail.
No. Chances are that avr-gcc is not 3.4.3. Try avr-gcc --version. You
can move avr-gcc to a name reflecting its version (e.g., mv avr-gcc
avr-gcc-8.1.2), and then symlink avr-gcc to avr-gcc-3.4.3 (ln -s avr-
gcc-3.4.3 avr-gcc).
If yes, how do i rectify this ?
Here is the output i get..(the commands are in bold)

(2) I tried checking the nesc versions as suggested in Lesson1 of
the TinyOS 2.x tutorial
Here is the output i got :

(3) But when i try to check the version of nesc1(which i guess is
invoked by nescc & is at the bottom of the ncc call chain) i get this
[EMAIL PROTECTED] tinyos-2.x]$ which nesc1
/usr/bin/which: no nesc1 in (/usr/local/arm/3.3.2/bin:/opt/

(4) I also ran the tos-check-env script and checked the MAKERULES
environment variable & here is what i got

(5) When i try to compile the Blink app in /opt/tinyos-2.x/apps I
get a huge list of errors as before, the last 3 lines of which are
as follows :
In component `BlinkAppC':
BlinkAppC.nc:51: cannot find `Boot'
make: *** [exe0] Error 1
The last line looks suspiciously similar to what is mentioned in
Lesson1 of the tinyos-2.x tutorial. So am I invoking an older
version of the nesc compiler, as is menetioned in the tut ?
Also, the 2nd last line says "cannot find `Boot' "...To you(David,
Phil) does this give some hint as to what could the problem
probably be ?
Your TOSDIR environment variable.
My guess is that if you fix your avr-gcc and your TOSDIR, things will
work OK.
Phil
