[Contiki-developers] Micaz: attempt to use poisoned SPMCR error

[George O. <G.O...@br...>]

Hello all

I have been running regression tests locally with current master (fff769a) and a couple of micaz-related tests fail, including hello-world.

If run manually, it throws this:

contiki-2.x/examples/hello-world (master)$ make TARGET=micaz
  CC        ../../cpu/avr/dev/flash.c
In file included from ../../cpu/avr/dev/flash.c:4:0:
/usr/lib/gcc/avr/4.7.2/../../../avr/include/avr/boot.h:112:16: error: attempt to use poisoned "SPMCR"
make: *** [obj_micaz/flash.o] Error 1

The test passes on Travis so I am suspecting it may be caused by different versions of the toolchain between travis and my system. That's what I have installed:

$ dpkg -l | grep avr | cut -f 3-40 -d " " 
avr-libc                                    1:1.8.0-3 
binutils-avr                                2.20.1-3     
gcc-avr                                     1:4.7.2-2

Travis is slightly older:
Setting up binutils-avr (2.20.1-2) ...
Setting up gcc-avr (1:4.5.3-3) ...
Setting up avr-libc (1:1.7.1-2) ...

Anyone have any ideas for a proper fix, other than rolling the toolchain back?

Thanks for your time
George
