Out of memory when building Erlang on EV3 running release ev3dev-jessie-2015-12-30

[jfcloutier]

While I could build Erlang from sources in the previous release (ev3-ev3dev-jessie-2015-09-13), I now run into an out of memory condition.

Note that I MUST build Erlang from sources in order to install an 18.* version which I require.

Any suggestion?

Thanks!

Don't compile on your EV3. Use brickstrap.

Or mount more swap as in #520.

[jfcloutier]

Trying both. Thanks!

All good. Thanks again.
