[rrd-users] Failed to create graphs

I have written a simple C program to collect CPU usage and Memory
usage from a linux kernel, and plot them using RRD.

This code seems to be working fine on Red Hat Linux machine, but when
I actually cross-compile the same program to suit PPC85xx (Power PC
architecture) and run the program, data collection seems to be working
fine, i.e ".rrd" file gets created and i can see it getting updated.
However, when i plot this .rrd on the PPC 85xx, teh graph.png file
gets created, but its size is 0KB.

What do you think is the problem here, that the same program works on
Red Hat Linux standalone machine (.rrd file created, graph works
fine), but doesnt work on PPC85xx machine (.rrd created, but graph is
of 0 size)?

Could it be any of the libart or any other graphing library being
screwed up on 85xx? I am using different versions of RRD on LInux
machine and 85XX machine.

Linux RRD version - 1.2.10
PPC85xx - 1.2.7
