[osg-users] [build] iv file not being read

[Mattias Helsing]

Hello Abhinav,

There is nothing for anyone to go on to even try to help you. The code
snippet is not even osg code so no chance for us to know anything
about what it does.

* use a debugger to see what "readAll" returns and why
* crank up OSG_NOTIFY_LEVEL
* see Paul Martz top 10 debugging tips at
http://www.skew-matrix.com/bb/viewtopic.php?f=6&t=5

cheers
Mattias
