[rrd-users] "rrdtool: can't resolve symbol 'posix_fadvise'" What does this mean?

[Martin]

Hi,

I'm setting up 1-wire net to log different temperature sensors.
I have a Seagate Dockstar running OpenWrt, OWFS and RRDTool. 
My sensors work fine but I have problem with RRDTool. 
I have no idea what "rrdtool: can't resolve symbol 'posix_fadvise'" mean,
can someone give me a hint where to start looking?

rrdtool: can't resolve symbol 'posix_fadvise'
