Hello,
I was actually successful building xbmc (pvr) for the Pandaboard on Ubuntu 11.10 using the TI SGX libraries.
After installing the packages mentioned in the README.ubuntu file (plus the TI 'libgles*-sgx-omap4*' and 'libegl1-sgx-omap4* files) I called:

Code:

./bootstrap
./configure --enable-gles --enable-neon --disable-debug
make -j2

I don't know which other parameters make sense to be used on the Pandaboard.

Running the 'make -j2' took 3 hours 30 minutes with a lot of pseudo warnings:

Code:

the mangling of 'va_list' has changed in GCC 4.4

I still have to do more tests as this morning I only started the build and called different menu items before going to work.

As some might be interested in this here is the full 'odyssey' getting a Ubuntu 11.10.

Originally I wanted to build XBMC it on the Linaro Ubuntu 11.10 builds for the Pandaboard but there is currently a problem generating the system for the SD-Card (at least from a Ubuntu 10.04 LTS Desktop system) because there is a failure adding the 'ti-uim' stuff (Linaro Bug #886101) with the linaro-image-tools. On a Desktop System with Ubuntu 11.10 and maybe 11.04 it should work.

I then tried the preinstalled Linaro Ubuntu Pandaboard image (with hardware accelerated graphics driver) which is ready for SD-Card deployment. I had some major display errors with this one. If anyone here wants to test it get the preinstalled Linaro Ubuntu 11.10 Desktop package here (packages for other boards like e.g. BeagleBoard, Origen, etc. are also available at this location):
http://releases.linaro.org/images/11.10/...u-desktop/

For installation of the image you can also use the command described here at the Ubuntu Image for ARM page using zcat and dd on one line:

As the above Linaro build had some problems I finally got to the official Ubuntu 11.10 Desktop release for armel omap4. The installation procedure wasn't that stable as it crashed several times after I selected the german keyboard layout but finally I got through it (this is no overheating issue as my Pandabaord has a big headsink attached; max temperature compiling XBMC was 47 °C).

Then I installed the TI graphics drivers (ubuntu-omap4-extras-graphics) as well as the multimedia packages (ubuntu-omap4-extras-multimedia - because of a conflict the metapackage had to be deselected again but the already selected packages for the multimedia parts could be installed) for Ubuntu 11.10 (aka Oneiric Ocelot):

With the multimedia package (gstreamer and gst) and graphics driver installed I wasn't able to play videos with Totem nor VLC. I could hear some sound but generally the system just hangs itself instantly.
Clarification: Totem 3.x directly crashes when I try to play an XviD encoded AVI file (haven't tried an *.mvk with h.264 yet). VLC uses it's own code for decoding (not gstreamer) and plays the video on the X desktop in a window (TOP tells me it uses ~34% of CPU). When I hit the Stop button of VLC the X desktop crashes and is restarted. When I try to play the XviD fullscreen it becomes a slideshow (lots of skipped frames).

So far I've not yet tried it again without those packages as at least some hardware acceleration would be nice.

Update 2011-11-15: With the latest TI update released yesterday the crashes trying to play a video file seem to be gone at least with Totem 3.x (TI-packages from ppa: ubuntu-omap4-extras - 1.1 - 2011-11-14, pvr-omap4 - 1.7.9.2.1.7-1 - 2011-11-09, and so on). Playing an XviD video at 1:1 sized window the CPU usage is at 15% but there are some screen glitches at the lower half of the screen (it think I read this in a bug description...seems to be a known but still unresolved problem). The glitches also show up on fullscreen and it looks as if some packages are dropped but it's nowhere near the previous slideshow.
VLC as well as XBMC tests follow shortly.
Update 2011-11-20: xbmc is playing XviD (SD) content pretty well. Currently it's only too slow when you play HD content. Maybe I take a video and put it on Youtube when I get the time.
VLC on the other hand wasn't running as good as Totem, but I think that could have been expected. It seems it's not using the acceleration support offered by the TI components.
