are you using the Pd-extended builds or did you build Gem yourself?

afaik, Pd-extended does not link against libv4l, thus you do not enjoy it's
pleasures.
simply do
% ldd Gem.pd_linux | grep -i v4l

yep. I'm using pd-extended and yep. Nothing for grep.




finally: afaik, you can force an application built without libv4l to use it
by employing some pre-linker magic. ("LD_PRELOAD_LIB=/usr/lib/libv4l.so pd
-lib Gem" or the like) - please see the README.txt that comes with libv4l
for instructions.

yep. This works:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/pd

Thanks!
