do it. Building on the ERL would be interesting also as it's meant purely as a run environment and most of the build chain doesn't exist and would have to be installed. At one time when I was messing with the BIND9 DNS server I'd thought about building an
ER build virtual machine (it's an ARM CPU) but didn't go through the trouble. I just moved my DNS and DHCP to a RasPi where it's all much easier.</span><br>

<div>Rasmus Lerdorf has an interesting (older) blog post about upgrading the version of php on the edgerouter. He installed gcc onto his ERL and compiled his code. He noted that there wasn’t a tool chain to target the cpu on this device for him to compile from
another machine. It worked out well and it’s actually part of the production builds now. </div>
