[Freeswitch-users] Cross compiling freeswitch for raspberry pi

Wed Jan 1 21:01:17 MSK 2014

Is cross-compiling an academic exercise?  If not, why not just natively
build it?  Natively building Asterisk or FreeSWITCH is as straightforward
on the Raspberry Pi as it is on more mainstream platforms.  Here's how I do
it:

It takes awhile, but doesn't require any head-scratching.
