Dear List,
I'm planning to buy a Raspberry Pi sometime soon, and I'd like to know the implications of the ARM11 chip on the use of Pd. I know nothing about the differences in architectures, so i'd like to know :
- why an ARM chip would be a problem for compiling, installing and running
Pd,
- if there exists another option that's up to date (Pda seems a bit old),
- if Libpd could be used instead (given that i only want to run Pd patches
on the Raspberry Pi, I don't need to edit anything on it).
Thank you in advance!
Cheers!
Pierre.

At work, I use an iPhone ARM7, and an Android ARM7, with basically the same libpd build on each.
I'm using it through the m_pd.h interface as much as possible instead of libpd's own ; either can be used.

It's not a problem--Pd compiles and runs on the arm architecture. Android devices for example have arm processors. Debian pure data packages are available for arm.
compilation-wise... there's some gcc options that you use to specify arm architectures. I'd say "nothing to it", but you'll most likely have to play a bit to find the differences.

Don't you want to try the graphics processor on the R. Pi? At the very least, it should be good enough for tcl/tk.
Thank you in advance!

That's good news! I suppose Debian packages can't be installed in Fedora, can they?

If Pd can be installed then I'll definitely stick to it.

No--planet CCRMA has some i386 pd packages, but not arm. If you want to run Fedora and Pd, you will need to compile it. If only you knew the power of the dark side, and by dark side, I mean Debian.
If you didn't get your pre-order in time for this batch, you'll have to wait a month, I bet. By the time I got to work this morning, it was too late.
i figure it won't be too long before nearly everyone including planet CCRMA has a build going specifically for the Pi. there' s a very good chance the Pi Foundation can license the design to other makers, so by May or so i'd bet a number of different places will have them in stock. the biggest issue for me is how much DSP performance you get out of something whose speed matches the iPhone 3GS. the awesome thing would be to put their display engine to work doing DSP but i think that's a long way down the line if ever due to the limited API access. i started a thread about this a bit ago and if i remember, the falling down point of ARM was that it didn't handle floating point well. i'd be curious how much these devices could be pushed.

There are some fedora packages of pd floating around. It would be great for someone to update them and include them in the pure-data SVN or some repo somewhere. Also, if someone makes a fedora package .spec file for the Library Template, it'll be really easy to package lots of other libraries for Fedora.
If you get Debian running on the Pi, then just apt-get install puredata.

I'm not sure how easy it is to generalize ARM platforms though. The processor in the RasPi is an ARM11, compared to for instance the Cortex-A found in beagleboards and other devices it has quite a reduced instruction set and doesn't support stuff like NEON, which can be very beneficial for media applications (not sure if Pd could make use of it though).
Talking about ARM personally, I'm interested in getting PD and Gem (preferably pd-extended) running on the Pandora, which has a Cortex-A8 like the beagleboard. I have tried the debian package here http://enchevetres.org/doku.php?id=tek:puredata inside the pandebian program (a chroot to run debian packages for the pandora os), but the program was completely unusable.
If anyone has success getting pd-extended compiled for Cortex-A8 from source I'm very much interested in any tips.

If you have Debian running on the Beagleboard, building Pd-extended should just be a matter of following the standard Debian instructions. Start with BuildingPdExtended on puredata.info.

i figure it won't be too long before nearly everyone including planet CCRMA has a build going specifically for the Pi. there' s a very good chance the Pi Foundation can license the design to other makers, so by May or so i'd bet a number of different places will have them in stock. the biggest issue for me is how much DSP performance you get out of something whose speed matches the iPhone 3GS. the awesome thing would be to put their display engine to work doing DSP but i think that's a long way down the line if ever due to the limited API access. i started a thread about this a bit ago and if i remember, the falling down point of ARM was that it didn't handle floating point well. i'd be curious how much these devices could be pushed.

No--planet CCRMA has some i386 pd packages, but not arm. If you want to run Fedora and Pd, you will need to compile it. If only you knew the power of the dark side, and by dark side, I mean Debian.
If you didn't get your pre-order in time for this batch, you'll have to wait a month, I bet. By the time I got to work this morning, it was too late.
