How to build ArduPlane 3.5.1 with Navio support

Hi,

We need Arduplane-3.5.1 for its Quadplane support. It’s not on the Navio repo, so I’ve tried following the instructions on Archived: Building for NAVIO+ on RPi2 — Dev documentation including the 4.8 compiler install and checking out the ArduPlane-3.5.1 tag from the official repo to build from source on the Pi. Unfortunately I’m getting repeated:

cc1plus: error: unrecognized command line option '-std=gnu++11'

and the compile aborts. When could we expect to see a working 3.5.1 on the Navio repo? Alternately does anyone recognise or have a work around for the compile error I’m getting?

Thanks,
Robin

Note the binary is available here: http://firmware.ardupilot.org/Plane/stable/navio/ArduPlane.elf

I’d still like to work out the compile problem if anyone can help.

Thanks,
Robin
