On Ubuntu 9.10, If we just download puredata autobuilds from: http://autobuild.puredata.info/auto-build/ ,  we could not install it on Ubuntu 9.10 just yet because there are these requirements: libmagick++10 and libmagick10, which are not in Ubuntu 9.10 repository.

My workaround: download both in .deb from the Ubuntu inteprid security repository:

http://packages.ubuntu.com/intrepid/i386/libmagick10/download
http://packages.ubuntu.com/intrepid/i386/libmagick++10/download

 Then, install libmagick10 first, then libmagick++10 ..

 Then.. Ta-da .. pd-extended from the autobuild is gonna be easy to install by just double-clicking on the desktop.

One bug I found out since the release of the beta of Ubuntu 9.10 (and I couldn't believe the bug is still around now although there is no such problem on Ubuntu 9.04) is this:

My soundcard: RME Hammerfall Multiface I (now the merchandise on sale is updated to version II, product page: http://www.rme-audio.de/en_products_multiface_2.php) did not start after booting Ubuntu 9.10 although the required package  alsa-firmware-loaders is present. Normally, if alsa-firmware-loader is installed, during the boot, /usr/bin/hdsploader will automatically install firmware for HDSP which enable the soundcard to work (and was working very well with Jack on many Linux distributions).

I checked by running:

$ hdsploader
hdsploader - firmware loader for RME Hammerfall DSP cards
Looking for HDSP + Multiface or Digiface cards :
Card 0 : RME Hammerfall DSP at 0xfdcf0000, irq 16
Upload firmware for card hw:0
Unable to open file '/lib/firmware/hdsploader/multiface_firmware_rev11.bin' for reading

Hmm!! Okay.. so this time a .bin for the firmware loader is missing? Hahhah quite silly, but sounds easy to solve. I checked in /lib/firmware/ .... hey!!! There's no hdsploader in there.. strange enough.

So, ok.. one of the easy workaround comes to my idea: Make It.

1. check if you already have build-essential installed on the system

2. visit ALSA Project's main page: http://www.alsa-project.org/main/index.php/Main_Page

3. see what version of ALSA I got on Ubuntu 9.10: comes out 1.0.20

4. download the alsa-firmware source code from the alsa-project page. Now I see version  alsa-firmware-1.0.20 but any older / newer version should work with no complications, I hope.

5. extract it, go into the directory, and ./configure

6. and make

7. Done! now go into directory hdsploader and you'll see this file: multiface_firmware_rev11.bin in it, just what we need

8. sudo mkdir /lib/firmware/hdsploader and sudo cp multiface_firmware_rev11.bin /lib/firmware/hdsploader

9. run hdsploader

10. … (the system is uploading the firmware to the Hammerfall DSP Multiface and...) Yay! The red LED (Host Error) was blinking then goes off! Now it's ready to use!!!

. . .

But why do I have to do this anyway? It kinda sucks + is so silly.

after i've been testing Ubuntu Karmic (version 9.10) beta release, i decided to install puredata extended version (pd-extended) which is downloadable as .deb from http://puredata.info/downloads but now installing directly from that pd-extended .deb doesn't work anymore. it requires ttf-bitstream-vera from Ubuntu Jaunty, libmagickcore1, libmagickwand1, libmagick++1 (also from Ubuntu Jaunty because in Karmic, it's libmagickcore2, libmagickwand2, libmagick++2 instead).

so i searched and download .deb directly from Jaunty packages:

http://packages.ubuntu.com/jaunty/i386/libmagick++1/download
http://packages.ubuntu.com/jaunty/ttf-bitstream-vera
http://packages.ubuntu.com/jaunty/libmagickcore1
http://packages.ubuntu.com/ko/jaunty/libmagickwand1

then force installing them with sudo dpkg -i (each .deb package names that we've just downloaded)

if the installation went well, the pd-extended .deb should be able to install fine. i tried the pd-extended from the nightly build (now Pd-0.42.5-extended-20091004-ubuntu-jaunty-i386.deb) and the installation also went smoothly.

i hope there will be a better workaround later when Ubuntu Karmic and the new pd-extended is fully released.
