by luigi rensinghoff 26 Apr '04

26 Apr '04

Hi List ! I just wanted to check out pd on Winows XP and have a look at GEM and i alwyas get that error see subject So my question: Where do i define the name of the video driver at all ??? Does anybody have it running on XP. Since ia am generally using Linux i would switch as well, but my videocard works better under XP, because i can have output on 2 screens. Thank you for a solution.... Cheers Luigi __________________________________ Do you Yahoo!? Yahoo! Photos: High-quality 4x6 digital prints for 25¢ http://photos.yahoo.com/ph/print_splash

Zexy and PDP Compilation Problems
by Ian Smith-Heisters 26 Apr '04

26 Apr '04

Hey list, I'm pretty new to compilation of things not made by me, so bear with me if this is moronic. I've downloaded the zexy and pdp sources from the CVS, and am having problems comiling them on Debian Sarge kernel 2.6.3. When I go to the zexy directory (/usr/lib/pd/externs/zexy/src/), read the instructions, alter the makefile to suit my directories, and type make, it says "make: *** No targets specified and no makefile found. Stop." So I give it a target with "make makefile.linux" and I get "make: Nothing to be done for `makefile.linux'." So I type "make clean" and I get "make: *** No rule to make target `clean'. Stop." I'm guessing this is a pretty simple error of ignorance to the workings of make. So. PDP. I type "./configure --prefix=/usr/lib" it works. I type "make" and I get: pdp_imageproc_common.c: In function `_sign': pdp_imageproc_common.c:292: warning: use of cast expressions as lvalues is deprecated make[2]: *** [pdp_imageproc_common.o] Error 1 make[2]: Leaving directory `/usr/lib/pd/externs/pdp/system/image' make[1]: *** [common] Error 2 make[1]: Leaving directory `/usr/lib/pd/externs/pdp/system' make: *** [pdp_all] Error 2 ...after a bunch of the usual make output. I tried it as root and as a regular user. I have libgsl0 and libgsl0-dev and libquicktime1 and libpng installed from apt-get. So, yeah. Any help would be very much appreciated. -ian

Error: DSP loop detected (some tilde objects not scheduled)
by derek＠x-i.net 25 Apr '04

25 Apr '04

Hi all, I'm trying to build a patch which allows the order of a signalprocessing chain to be rearanged... for example, to put the delay either before or after the reverb. Thre problem is that when I conect the outlets and inets of the [pd delay] and th e[pd reverb] that I have created subpatches together, I get the error "DSP loop detected (some tilde objects not scheduled)". I tried putting [*~ 0] objects in the way, or even running the signals through subpatches which can be switched on and off with [block~], but still no dice. I've been very careful to not actually *create* any feedback loops in the patch, as you will see if you look at the example I have attached. Is there any other way of doing this? Or is there something wrong with my logic? thx! d.

recursive abstractions
by Tim Blechmann 25 Apr '04

25 Apr '04

hi all, i'm curious if someone has tried to build recursive abstractions in pd ... if so, i'm really interested in how you did that ... cheers...

Re: gridflow on 10.3, with pd (fwd)
by Mathieu Bouchard 25 Apr '04

25 Apr '04

I finally isolated the problem in combining GF/Pd/X11/OSX, and it is not GF's fault. It boils down to this: pd/src/makefile links Pd to Tcl/Tk (using -framework Tcl -framework Tk in LDFLAGS) but this is wrong, because it does so on the Pd server, which doesn't run any Tcl code! It would be so nice if this were fixed in all three branches of Pd (miller,devel,impd). I've made the fix only in makefile though. it would be better if it were made in configure.in then propagated to relevant files. ---------- Forwarded message ---------- Date: Wed, 31 Mar 2004 15:34:24 -0500 (EST) From: Mathieu Bouchard <matju(a)sympatico.ca> To: James Tittle II <tigital(a)mac.com> Subject: Re: gridflow on 10.3, with pd On Wed, 31 Mar 2004, Mathieu Bouchard wrote: > The problem with the X11 thing is that for some mysterious reason it does > not allocate the Window while at the same time appearing to be doing > so. Then when I try writing in the window, I get a X11 error and it goes > boom. Ok, an update on this, I used GDB to figure things out, and here's what it does look like: 1. For some weird reason, the server links with both Tcl and Tk. I would have expected at most Tcl, and actually, given my experience with Pd, I would have expected none, as I haven't seen any calls to Tcl in the server code. 2. Tk/OSX seems to define X11 functions, such that although GridFlow is dynamically linked by gcc/ld to work with libX11.so, it gets all its X11 functions from Tk, because apparently the Tk port to OSX involves a kind of X11 emulator implemented with Quartz, _and_ this emulator doesn't work well enough that GridFlow could display anything. Which leads to: #0 0x0b0e71c8 in TkMacOSXGetDrawablePort (drawable=4194305) at tkMacOSXSubwindows.c:964 #1 0x0b0e61d4 in XResizeWindow (display=0x32b620, window=4194305, width=16, height=16) at tkMacOSXSubwindows.c:284 #2 0x00988d88 in FormatX11::resize_window(int, int) (this=0x1b3370, sx=16, sy=16) at format/x11.c.fcs:374 #3 0x00b0c844 in void FormatX11::grid_inlet_0<long>(GridInlet*, int, Pt<long>) (this=0x1b3370, in=0xdde620, n=-1, data={p = 0x0, start = 0x0, n = 0}) at format/x11.c.fcs:413 So GridFlow wants to use X11, and it ends up in Tcl/Tk's hands, in the frigging server. Neat, eh? ________________________________________________________________ Mathieu Bouchard http://artengine.ca/matju

If you make a [plugin~ freeverb3] and send it a print message, it will spit out the usage on the console. Mine says: This is plugin~ version 0.2 -- NO WARRANTY -- Copyright (C) 2000 Jarno Sepp?nen freeverb3: "Freeverb (Version 3)"; control 6 in/0 out; audio 2 in/2 out Loaded from library "/usr/lib/ladspa/cmt.so". Control input(s): #1 "Freeze Mode" #2 "Room Size" #3 "Damping" #4 "Wet Level" #5 "Dry Level" #6 "Width" Control output(s): Audio input(s): #1 "Input (Left)" #2 "Input (Right)" Audio output(s): #1 "Output (Left)" #2 "Output (Right)" Maybe that gets you started? [plugin~ freeverb3] only has 3 inlets, 2 for audio, 1 for controls, and there are 6 controls. Hope that helps. -jason http://noisybox.net
