supernova 3.7 compile fail on ARM (Beaglebone)

[danstowell]

On my Beaglebone Black, supercollider compiles fine with supernova turned off. Trying to compile supernova results in:

Sorry @timblechmann but please allow me to ping you on this one too, it's beyond me.

[timblechmann]

gcc 4.7.2 is an ancient compiler ... it is not even the latest gcc-4.7, as the latest 4.7 bugfix is 4.7.4. i'd recommend a more recent one.

fwiw, according to wikipedia, beaglebone uses a single-core arm cortex a8 cpu. on this type of CPU, one will probably be better of with scsynth, as the wire buffers can be shared among different synth.

Oh that's a rather good point - not much point worrying about supernova on such a device. OK I'll just mark it as wontfix then.
