[Pdns-dev] PowerDNS on a Raspberry Pi running NetBSD

[Christof Meerwald]

Hi,

just tried running PowerDNS (Recursor 3.5.2 and auth 3.3-pc1) on my
Raspberry Pi (with NetBSD 6.1) - and it worked with some small code
changes:

So, time_t is defined as int64_t (i.e. long long), therefore I needed
to add another overload to Logger to avoid overload resolution
disambiguities.

__sync_fetch_and_add doesn't seem to be supported on that particular
platform, but there is a sys/atomic.h header providing similar
functions.
