[hid] undefined symbol: hid_platform_specific_free
by Christian Klotz 08 Nov '04

08 Nov '04

Hi Hans, hi all I want to try your [hid] object - in this case on a gentoo linux system. But when pd tries to load hid.pl_linux I get the error mesg undefined symbol: hid_platform_specific_free and the library wont be loaded. Do you or anybody else know whats the problem? thanks, regards Christian --- Christian Klotz Kunsthochschule Kassel / School of Arts Kassel ::digitalpool

'Consistency check failed: canvas_create_editor'?
by Roman Haefeli 08 Nov '04

08 Nov '04

hi what does this error-mesage mean: 'Consistency check failed: canvas_create_editor' ? i get it, when i dynamically open patches by messages to pd. as far as i can say it happens only when in try to open bigger patches (>30kB). is this caused by an error in my programming or a problem in pd? is there a way to avoid this? thanx roman

Hi Tim... I checked this out to see if I could merge my newest changes in... but I can't compile it - I get errors like: g_io.o(.text+0x706): In function `vinlet_perfsimd': /home/msp/pd/attic/cvsdevel-copy/pd/src/g_io.c:156: undefined reference to `copyvec_simd' (I'm on a P4, running Fedora 2 with its default development environment.) thanks Miller On Fri, Nov 05, 2004 at 05:17:55PM +0100, Tim Blechmann wrote: > hi all ... > > i created a devel_0_38 branch that is based on miller's 0.38-test7 ... > > i would strongly suggest to deprecate devel_0_37 and work on devel_0_38. > > most of the features of devel_0_37 are still available and i hope i > haven't missed or broke anything ... > > have a lot of fun with it ... > > cheers ... tim > > -- > mailto:TimBlechmann@gmx.de ICQ: 96771783 > http://www.mokabar.tk > > After one look at this planet any visitor from outer space > would say "I want to see the manager." > William S.

added print method to comport external
by Marc Boon 07 Nov '04

07 Nov '04

In search for a way to send strings to an usb character display from within pd, I came upon the comport external: http://iem.kug.ac.at/ritsch/programmier/pd_externals/comport/ Although a bit outdated, it worked right out of the box, but lacked an implementation of the print method, although the function header was already present as a comment in the source. The only way to send characters was by sending ascii codes as float messages. Since I don't know how to convert a string message to a series of float messages, I decided to implement the missing print method. I also inlcuded the /dev/ttyUSB0-7 devices in the device list, to facilitate opening an usb serial device, like my Matrix Orbital LK204-24-USB. The only problem still is that I can't send a message containing comma's, because the message is then split in two messages. Any suggestions on how to do this? Of course, I could also have used the system object like this [system echo "Hello, world!" >/dev/ttyUSB0], but I also need input from the lcd module, and the system object doesn't provide that.

hi all ... is there any way to change the behaviour of the pd-cvs list that diffs of *.pd files won't be sent? i'm sure, i'm not the only one having problems when reading diffs of pd patches ... cheers ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk After one look at this planet any visitor from outer space would say "I want to see the manager."

Gem [create( freezes system
by Christian Klotz 07 Nov '04

07 Nov '04

Hi again, after trying to get Gem completely working for a couple of days on my linux machine with sis chipset, I tried gentoo with kernel 2.6.9. I have a nVidia Geforce 5700 in there and everything seems to work. There is the latest nvidia driver installed 1.0-6111 but as far as I click the create message the system freezes. I read something about old drivers (in 2002) with the same behaviour but I couldnt find anything related to the current one. Does anybody know something about this? regards, christian --- Christian Klotz Kunsthochschule Kassel / School of Arts Kassel ::digitalpool

Undocumented pd ( midirealtimein and midiclkin etc) ?
by rodney 07 Nov '04

07 Nov '04

Hi all, I have seen references to midirealtimein and midiclkin but no documentation on them. Is that because they do not actually work? What other 'undocumented' PD native objects are there? Using % for 'mod' is one I guess? Rod. Rodney Berry

Also try several other numbers here. Midi is a mystery. ;) If you're an early adopter, you might want to test Pablo's new ALSA seqnecer patches for Pd. Links should be in pd-dev and they also were posted in the pure-data.sf.net patch tracker. > modprobe snd-virmidi gives > > FATAL: Error inserting snd_virmidi > (/lib/modules/2.6.4-52-default/kernel/sound/drivers/snd-virmidi.ko): No such > device > > beside the two soundcards it is not possible to install virmidi. Yast is > telling me I/o or IRQ conflicts. Strange. I'm no Suse expert at all, but snd-virmidi should not generate any IRQ problems: it's a virtual card without IRQs. Maybe you miss some device files in /dev/? Strange, normally Suse has quite good ALSA support (as the ALSA team is employed at Suse). Ciao -- Frank Barknecht _ ______footils.org__

I don't know if and I doubt that this is the reason for your troubles, but device files should be owned by root generally. You can make it so by: $ chown root.audio /dev/midi* /dev/snd/* $ chmod g+rw /dev/midi* /dev/snd/* Does (hw) midi work with other software like MusE or pmidi?

So virtual midi connections to other midi software will not be possible. Hardware midi through the SiS card should work, though. Normally "client 72" is mapped to /dev/midi2. To access it from Pd, use "pd -mididev 3" (because 3=2+1) Ciao -- Frank Barknecht _ ______footils.org__
