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

[Steve Shipway]

fadvise is the function used for providing hints for memory-mapped IO functions, which means rrdtool 1.4 (I think) so I'm not sure how you're getting this when you say you installed RRDTool 1.2!

The error message indicates that the RRDTool libraries cannot find the required function in the dynamically-loaded libraries.

You might need to install the appropriate libraries for mmap and fadvise support?  Or you might need to recompile rrdtool from the source code for your particular flavour of unix?

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?
