I'm not sure if my last message went through b/c of the file limits, so I
guess I'll repeat the message except link the files to a file hosting site.
I'll start with replying to soliton's questions first. Here are the
printouts for where sdcc, gpasm and gplink are installed.

[end of printout]
As you can see, sdcc is installed in /usr/local/bin, while gplink and gpasm
are installed in /usr/local/share/gputils/.
Now, responding to jan's suggestions:
1. gputils is installed in /usr/local/bin/
2. location of the lkr files are in /usr/local/share/gputils/lkr/
3. location of crt0i.o is in /usr/local/share/sdcc/lib/pic16/. However,
there are multiple copies of them, as shown below:

Anyway, there is one strange thing that I have found. I have modified jan's
template as shown in the attached zip file and still got the following error
message:

[error message end]
However, when I have modified another Makefile and code similar to the one
Xiaofan's last reply suggested, I manage to get a hex file created in the
end. However, it had the same behaviour as the one I have made with piklab,
which is my code doesn't automatically execute whenever I apply an external
power supply. It only executes when I plug in my PICKIT2 after instructing
PICKIT2 to be on with the command "pk2 -on". I'm beginning to suspect that
this is a hardware problem, perhaps with the power on timer and the brown
out register.
Btw, the files are in http://www.mediafire.com/?4bxc9z2t94m for the software
project folder using Jan's Makefile template, and
http://www.mediafire.com/?bzz9kt467qm for the software project folder using
Xiaofan's suggested Makefile template.
Thanks for your patience,
Stanley
