Problems viewing images with pv
Hi,
Photon installation on my embedded sh7780 target seems to work well - I can start ped, shelf and other applications. I
cannot view files with pv or use bkgdmgr, however.
Here is my session
# Welcome to QNX Neutrino on HiCO.SH7780

#
pv starts and shows an error window with text "Unable to load example.jpg file"
The example.jpg is a simple image from our web site (I have also tried different images).
What do the "RegionSet(): rid=42 not found..." mean? Am I maybe missing some resources on the target?
BTW: On linux I always use 'strace -e open <program>' in situations like this. Is there a similiar way to get a trace of
all resources which a given process tries to open on QNX? I'm aware of the dtrace project, but it probably won't yet
work on SH architecture.
