I am having trouble running any of the gridflow exmaples on PD. my gridflow directory is located at /usr/lib/pd/extra/gridflow. I created the .pdrc file in /home
I am a newb to this.So how do i add the CPLUS_INCLUDE_PATH for gridflow? also what is LIBRARY_PATH and LD_LIBRARY_PATH and  what is this path supposed to be?

hi,
I installed Gem here: /usr/lib/pd/doc/Gem .After doing so pd found Gem.pd_linux.I'll just highlight the errors i've faced so that it becomes easier for those who have dealt with installing pd with gridflow:

I know this is too much to ask but can you post detailed instructions(i'm new to linux..sorry..)

Sisil.

I have been trying to run the motion_detect.pd  and have been unable to configure the camera. I have installed v4l (format/videodetect.c). Does gridflow support any webcam?(i have a integrated Creative webcam on my laptop.) I read on a forum about some driver for the philips cam. How do i go about installing drivers for camera for gridflow?(i'm a newb...)(can i make any cam other than the philips one, which has drivers ,work?and usually from what source does gridflow get video?).

Thnks,
Sisil

Pure Data does work on windows. However will the gridflow libs work on windows as well? what if i use cygwin. Has anyone tried this before (i'm a newb...so any help is appreciated)

Sisil.

I just can find the #labeling file? i have gridflow 0.9.4 has it been replaced by some other file??
