Hello, I just installed Ubuntu 9.04, pd-ext 0.41.4 on my new Toshiba Qosmio F50-138 (GeForce 9700M GTS) and all works fine except the webcam with GEM. So i decided to download sources and compiled GEM with libv4l as describe at http://www.mail-archive.com/pd-list@iem.at/msg26631.html I have (./configure) :

[...]

...

LIBS : -lmpeg3 -ljpeg -ltiff -lGLU -lGL -lXext -lXext -lX11 -ldl -lz -lm -lpthread : -lftgl -L/usr/lib -lquicktime -lpthread -lm -lz -ldl - lquicktime -lpthread -lm -lz -ldl LDFLAGS : -shared -Wl,-export-dynamic

[...]

...

input-support use v4l : yes

[...]

...

GEM works fine after that, but [pix_video] still not work, i get in the Pd console : video driver 0: video4linux So nothing about video4linux2 :( What can i do ?

it seems like configure does not recognize that you have libv4l installed.

if you want to compile Gem with native libv4l support, make sure that you also have the _development_ packages for libv4l installed ("libv4l-devel" or the like on rpm-based distros)

Both (libv4l-0 version 0.5.8-1 and libv4l-dev version 0.5.8-1) have been installed with synaptic. I try apt-get install libv4l-dev, but i get a confirmation that i have the most recent version. I don't know if that can help you to understand but the pidip object [pdp_v4l2] works fine here.

if you want to just use the LD_PRELOAD hack, then you won't see the "video4linux2" line when starting Gem but it should work anyhow...

No, i don't want :) But if it is the only one solution, i will try it. Any Idea ? ++

oh, i somehow had the impression that you were using fedora. anyhow, you did as i would have told you :-)

No no, Ubuntu 9.04.

no, that's unrelated, as pdp does not use libv4l (yet).

good.

i think you might be missing pkg-config ("apt-get install pkg- config"), which is used by Gem's configure to detect relevant flags for installed libraries.

pkg-config was installed.

if this doesn't help either, you would need to post the entire configure output.

Ok Iohannes, that was the problem. All works fine now. Thanks a lot. ++

OK :

you have to use the latest svn from Gem, not the 0.91 release (which does not have libv4l support and will never have).
