Hi List, Ok nearly there making pidip on an fc3 ccrma machine. I uncompressed the pd source and the ffmpeg source and the configure when well. I did make clean. It went ok I did make and it went ok until I got this:- pdp_capture.c: In function `XMyClientWindow': pdp_capture.c:123: warning: implicit declaration of function `XWindowByProperty'pdp_capture.c: In function `XMyGetWindowImage': pdp_capture.c:201: warning: dereferencing type-punned pointer will break strict-aliasing rules pdp_capture.c:329: warning: implicit declaration of function `XDestroyImage' pdp_capture.c:433: warning: implicit declaration of function `XGetPixel' pdp_capture.c:533: warning: dereferencing type-punned pointer will break strict-aliasing rules pdp_capture.c:539: warning: dereferencing type-punned pointer will break strict-aliasing rules pdp_capture.c: In function `pdp_capture_do_capture': pdp_capture.c:562: error: `XTextProperty' undeclared (first use in this function) pdp_capture.c:562: error: (Each undeclared identifier is reported only once pdp_capture.c:562: error: for each function it appears in.) pdp_capture.c:562: error: syntax error before "window_name" pdp_capture.c:574: error: `XError' undeclared (first use in this function) pdp_capture.c:655: warning: implicit declaration of function `XGetWMName' pdp_capture.c:655: error: `window_name' undeclared (first use in this function) make[1]: *** [pdp_capture.o] Error 1 make[1]: Leaving directory `/usr/lib/pd/externs/pidip/modules' make: *** [pdp_pidip_all] Error 2 [root@localhost pidip]# Can anyone help me out here? what does it mean? dominic

instaqlling pd on win xp pro
by charles thorley 05 Jul '05

05 Jul '05

hey all...i posted a question on the puredata.antibling.org forum, but so far noone's anwswered me, and i'm getting a little bit itchy. i recently downloaded and installed pd on my xp pro box, and when i try to run pd.exe, it thinks for a moment, then seems to do nothing. however, pd.exe is actually running in the process manager. i'm hoping someone has some insight as to how i might make pd a little more accessible. :) thanks in advance, charles __________________________________________________ Do You Yahoo!?

audio input does not work
by Yvan Vander Sanden 04 Jul '05

04 Jul '05

hi, I have just upgraded my system to fedora core 4, installed pd etc., but my sound input is not working. dac~ gives output, for example when I connect an osc~ to it. adc~ has no input, however. I've checked the alsa mixer, and the microphone is on. (direct output works, and other applications like skype are working too.) I have configured pd (version 0.38.4) with --enable-alsa and --enable-jack. The jack server is started with: ----- [root@laptop ~]# jackd -d alsa -d hw:0 jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead ----- that should be ok, i have a 16bit soundcard in my laptop. After that, i start pd -jack: ----- pd -jack priority 8 scheduling enabled. memory locking enabled. priority 6 scheduling enabled. memory locking enabled. Configuring for UNIX Pd version 0.38.4 devel {OSS 2} {ALSA 1} {jack 5} courier ----- no errors here. The pd window gives me the output: Opened Alsa Client 128 in:1 out:1 Computing audio gives no error, except jack sometimes outputs the following message: **** alsa_pcm: xrun of at least 9.553 msecs But i don't get any input. Tried to connect adc~ to dac~, and also tried to connect adc~ with fiddle to see some output, but nothing is coming in... dmesg gives no errors either. I don't really know where to look now. I tried some older versions of pd, with the same result. Has anyone here encountered the same problems? regards, yvan vander sanden -- (\(\ (x.x) (")") This is the decapitated bunny virus.

GEM : text3d small bug
by cyrille henry 04 Jul '05

04 Jul '05

hello, unlike GEM Geos, text3d does not define a GLnormal. So it's normal depend on the last thing drawn to the sreen : light on the text depend on previus object. attachement is a small example. i think i've got official gem 0.90, compiled with FTGL (ubuntu linux). i just test on my computer...

amdf~
by Ed Kelly 04 Jul '05

04 Jul '05

Dear all, enclosed is an external I am working on to find the Average Magnitude Difference Function. It crashes PD at the moment, and I don't know why. I'm sure there must be a way to do this more efficiently - is my understanding of vectors right? and is it possible to compare two vectors in the signal block by input[i] > input[i+p] where *input is a pointer to a signal vector?

HID for new PowerBook users
by Max Neupert 04 Jul '05

04 Jul '05

hi list, if you are using a 2005 powerbook you will have fun trying this: 1. download the ams-tracker http://www.kernelthread.com/software/ams/download/AMSTracker.html and place it on the root directory of your hd. 2. run the patch for a simple theremin: rotate your laptop to contol tone and volume by rotation or control a cube that stays always leveled: i don't know how to stop the shell though, so you might want to kill all the amstracker threads after experimenting with it. it might crash pd too. any comments appreciated. max Links: http://www.kernelthread.com/software/ams/

blocksize and audiobuf on PDa
by David NG McCallum 04 Jul '05

04 Jul '05

List, Could you chaps who've got PDa working let me know what you've fiddled your audiobuf and blocksize to? I'm not really sure how to mess around with those. I'm on an HP h5500. Thanks! David -- __ _ _ _ _ __ ___ _ ___ __ _ _ _ ____ __ Music wants to be free http://sintheta.org

uh oh... more dumb pd/gem linux questins
by David Kendall 04 Jul '05

04 Jul '05

Hello Everyone So, after all the fussm the other day about compiling Pd on Fedra Core 4, I fonally managed to get Pd working. I am not sure I remember how I did it, but it involved a somhat intuitive, somewhat logical shifting of directories containing the relevant .h files. Now I want to compile GEM to run with Pd on Linux (yikes!), and I expect plenty of fudging around, to make sure that all the proper libraries are installed &c. I do have a simple question that I hope will speed up the compilation process, though. When the GemLibs documentation says: put the GemLibs near your Gem-src path. something like: <src>/GemLibs/ <src>/gem-<version>/src ... then, by "Gem-src path", do they mean the location within the Pd directory where the source code for GEM resides? (i.e. /home/david/pd/extra/gem/src) Or would the GemLibs source reside in a location closer to the libraries upon which gem/pd are dependent? (i.e. /lib/src/GemLibs) I understand that I will have to feel around to figure out exactly where all of my .h files should go. But if I can know to put the source code within the Pd directory, or near more general source libraries, then I think the process of figuring ou whre everything goes would be a lot simpler. As always, thanks in advance, and apologies if I am being dense here. ;-) David -- homepage - http://davidkendall.net mp3 - http://ruccas.org
