Hi list
I'm looking for some Pd-extended build for Ubuntu 11.04 x64 (Natty Narwhal, 2.6.38 kernel). I've tried to compile 0.42.5 by myself (with this guide : http://puredata.info/docs/developer/DebianWheezyAmd64 and http://ubuntuforums.org/showthread.php?t=1767292) but got stuck because of issues between 2.6.38, V4L and pdp.
The best thing would be to help Lorenzo get pdp working with v4l2 and remove the v4l stuff. You could also try removing pdp from the build, in externals/Makefile, see the variable LIB_TARGETS. Then at least you'll have all of Pd-extended minus pdp. Or another kludge is to make a symlink to the old v4l:
sudo apt-get install libv4l-dev sudo ln -s /usr/include/libv4l1-videodev.h /usr/include/linux/videodev.h

The best thing would be to help Lorenzo get pdp working with v4l2 and remove the v4l stuff.
It doesn't seem so trivial though... I hadn't understood correctly that pdp_v4l2 is actually part of pidip, not pdp.
So following the radical approach of totally getting rid of v4l in favour of v4l2 here's my first attempt where I brutally replaced pdp_v4l.c with the contents of pdp_v4l2.c, replaced #include <linux/videodev2.h> with #include <libv4l1-videodev.h> and renamed the setup function and symbol in the setup function to pdp_v4l (i.e. the object is still [pdp_v4l] when you load the pdp library).
It seems to work (only the [pdp_v4l] didn't test the rest) on a vanilla build of 0.43
I did some changes to configure.ac concerning the ability to pick up the pd source file (giving for granted puredata-dev is installed) and the videodev.h headers.
- changed the default prefix to /usr
- changed videodev.h to videodev2.h
Sorry this is all very hacky... but as I said I'm very new to this kind of 'packaging' thing.

packagers can easily install to /usr by specifiying "--prefix=/usr" in their packaging rules.

sorry for being so down-to-earth. the above mentioned issues shouldn't be too hard to resolve though, and it would make you skip the "packaging noob" status :-)

Ok. It would make sense then to have pdp_v4l2 in pdp. Anyhow pidip is still in the official source for 0.42 extended presented on the front page of puredata.info
That said I don't have the skills/time to create a pdp_v4l2 so I guess if the pidip code can't be used someone (tm) should pick up the task.

We can definitely help with the tricky bits. It would be a valuable
contribution to PDP. You could also contact Yves directly (the pidip
author) and see if he would be willing to let you include the pdp_v4l2
code in PDP as the same license.
At the very least, it should be easy to get pdp_v4l compiling again
using the new header.

Does V4L2 totally support PWC cameras' special options ?
I ask because V4L1 has an extension for it, and V4L2 doesn't, so, I was wondering whether V4L2 could cover all of PWC's options.
If not, then it's a good idea to use pdp_v4l.c in order to get to special features of those cams. (Though that doesn't work with most recent kernels... I just have to not upgrade it)

it seems like part of the brokenness of the wiki-page is, that Gem (and pd-pdp) are currently not in wheezy. at least for Gem i can confirm, that it (re-)entered Debian/testing yesterday. it was blocked for several days (and even removed from testing) by a transition of ImageMagick.

I managed to compile pd-extended by tweaking /externals/Makefile as Hans previously suggested :
#LIB_TARGETS += hid pdp pidip gem2pdp iem16 pdp_opengl postlude
LIB_TARGETS += hid iem16 postlude
I don't use pd to make graphics (for now ;) ), so i removed all the pdp-related libs. I can upload my build somewhere if someone needs it, just contact me by e-mail as im not always reading the list.
