Can anyone tell me if there is an existing problem or if I have to
install a fix for this? I ran tos-check-env. It worked fine.
I recently installed TinyOS-2. I am trying to compile either Blink or
Null in simulation mode. I am getting the following compiler (g++)
errors on the sample code:
declaration shadows global declaration
-fPIC ignored for target (all code is position independent). This is
followed by lots of compile-time errors.
I get the following output
make micaz sim 1>out.txt 2>err.txt
.........out.txt..............
