When I try to run tutorial code that works on other computers, such as
BlinkToRadio, I get warnings such as the following
/opt/tinyos-2.x/tos/lib/timer/VirtualizeTimerC.nc: In function
'VirtualizeTimerC$0$fireTimers':
/usr/lib/ncc/nesc_nx.h:272: warning: dereferencing pointer 'btrpkt' does
break strict-aliasing rules
/usr/lib/ncc/nesc_nx.h:272: warning: dereferencing pointer 'btrpkt' does
break strict-aliasing rules
BlinkToRadioC.nc:45: note: initialized from here
/usr/lib/ncc/nesc_nx.h:283: warning: dereferencing pointer 'header' does
break strict-aliasing rules
etc
and then an error
/usr/lib/gcc/avr/4.4.2/../../../../avr/bin/ld: BFD 2.17 internal error,
aborting at reloc.c line 445 in bfd_get_reloc_size
/usr/lib/gcc/avr/4.4.2/../../../../avr/bin/ld: Please report this bug.
make: *** [exe0] Error 1
Has anybody encountered this or any solution? i have tried compiling with
-no-strict-aliasing but the output is confusing, no warnings but the last
three lines are just colons which I do not understand.
