Issue solved, manual update of compiler from 4.6,3 -> 4.7.2 enables the make process. Similar problem also reported in post.

Using

• sudo apt-get update
• sudo apt-get upgrade

does not upgrade compiler. I used instruction according to How to upgrade GCC to 4.7+.

Have been running MySensors for some time now with a EthernetGW running on Arduino. To clean-up the installation, I'm trying to get the Gateway running on my Raspberry instead but something stops the make process.

pi@raspberrypi ~/MySensors $ ./configure --my-gateway=ethernet --my-port=5003 --my-transport=nrf24                       [SECTION] Detecting target machine.
[OK] machine detected: SoC=BCM2836, Type=Rpi2, CPU=armv7l, REV=a01041.

pi@raspberrypi ~/MySensors $ make

cc1: error: bad value (cortex-a7) for -mtune switch
Makefile:102: recipe for target 'build/drivers/Linux/log.o' failed
make: *** [build/drivers/Linux/log.o] Error 1

Any hints what I have done wrong ?
