Help with writing externals
by thewade 02 Apr '04

02 Apr '04

Hello faithfull list, I have a question reguarding writing externals. Ive never really built anything Ive written myself in linux sence my CSCI classes in college, can someone remind me as to how to build in the linux environment? Heres my makefile ----------------------------------------------------- LDFLAGS = -Wl,-export-dynamic -lasound -lrt -ljack LIB = -ldl -lm -lpthread -lasound INCLUDE = -I/usr/local/include BIN_DIR = ../general EXT= pd_linux sphere: $(CC) $(LDFLAGS) $(INCLUDE) -o $(BIN_DIR)/sphere~.$(EXT) sphere~.c fft-bin: $(CC) $(LDFLAGS) $(INCLUDE) -o $(BIN_DIR)/fft-bin~.$(EXT) fft-bin~. ----------------------------------------------------- but the compiler isint finding my m_pd.h I think, as I get: gcc -Wl,-export-dynamic -lasound -lrt -ljack -I/usr/local/include -o ../general/fft-bin~.pd_linux fft-bin~.c /usr/lib/gcc-lib/i386-redhat-linux/3.3.3/../../../crt1.o(.text+0x18): In function `_start\': : undefined reference to `main\' /tmp/ccAyKAvm.o(.text+0xf): In function `fftbin_tilde_new\': : undefined reference to `gensym\' etc... Also, how would I put both of these into one .pd_linux external through linking? Just provide two .c files to be compiled instead of one? THanks for the help! -thewade

I just use a [route $1] filter on the [midictlin] output. m. -----Original Message----- From: pd-list-admin(a)iem.at [mailto:pd-list-admin@iem.at]On Behalf Of Star Morin Sent: Friday, April 02, 2004 12:06 PM my problem is that i want to use the argument as the midi channel arg to a few ctlin objects, but only the first instance of the abstraction works, an it's midi omni (2nd outlet of ctlin disappears, thought, after adding $1). is there something that i'm missing? is there a better methodology of asigning a midi channel in the context of an abstraction? any help would be great - thanks! _________________________________________________ Scanned on 02 Apr 2004 20:11:09 Scanning by http://erado.com

hi list - i'm having some trouble that you guys might help w/. i've created an abstraction that i want to pass a single numeric argument to, an subsequently use that number as the creation arguments of some objects and sub patches. all good, works for everything *except* midi ctlin object. my problem is that i want to use the argument as the midi channel arg to a few ctlin objects, but only the first instance of the abstraction works, an it's midi omni (2nd outlet of ctlin disappears, thought, after adding $1). is there something that i'm missing? is there a better methodology of asigning a midi channel in the context of an abstraction? any help would be great - thanks! -star

Newbie... OSX-GEM
by IVAN Esquinca 02 Apr '04

02 Apr '04

Hello... Well, this is my first letter to this mailing list...Im really new to this software, Ive found it very interesting and growing...I still learning... I decide to use this software for its capabilities in live performances not only of sound but also of images.. in this respect, images, GEM is the external to use, as I understand... nevertheles, I havent been able to run it... as I say.. Im really new to this... nobody gides me only my eyes thru the documentation, patches, etc... anyway, I dont know if gem came in the first compiled pkg version(0.37) or in the next not pakaged version(0.37-1), wich I install later... The fact is that varius externals that I dont know yet are in the extra folder, in this folder is also the gem.pd_darwin file. In the doc folder are also other "new" folders, these are: abstractions, CVS, flext, GEM and tutorials. When I try to run any of the examples in the GEM folder, a list of errors is printed in the terminal widow. for example, with redsquare.pd this is printed: gemwin ... couldn't create gemhead ... couldn't create rotate ... couldn't create color ... couldn't create square ... couldn't create 01.redSquare.pd 1 0 0 0 (message->text) connection failed 01.redSquare.pd 2 0 8 0 (text->text) connection failed 01.redSquare.pd 3 0 0 0 (message->text) connection failed 01.redSquare.pd 4 0 0 0 (message->text) connection failed 01.redSquare.pd 5 0 0 0 (message->text) connection failed 01.redSquare.pd 6 0 11 0 (text->text) connection failed 01.redSquare.pd 7 0 6 1 (gatom->text) connection failed 01.redSquare.pd 8 0 6 0 (text->text) connection failed 01.redSquare.pd 9 0 8 1 (message->text) connection failed 01.redSquare.pd 10 0 8 1 (message->text) connection failed 01.redSquare.pd 17 0 11 0 (message->text) connection failed 01.redSquare.pd 18 0 11 0 (message->text) connection failed 01.redSquare.pd 19 0 11 0 (message->text) connection failed 01.redSquare.pd 20 0 11 0 (message->text) connection failed And eventough a window is opened, it is not functional.... In the other hand, I tried to use Jack server for direct the pd sound to another aplication(a sound editor), and also recive errors... -first, when I run Pd and the Jack server is not loaded, the terminal window says that the default conection with Jack server couldnt be stablished( the preferences of jack server are not configured to be the default output)...only that, everything seem to work correctly despite this... -second, when I turn on the Jack server, the first error doesnt apear, but the output still being the build-in not jack, so, I change the output in the audio preferences of Pd, and receive this as an answer in the terminal: Could not create format converter: error = 0x666D743F = 'fmt?' PaOSX_OpenCommonDevice: PAOSX_DevicePropertyListener failed. : error = 0x666D743F = 'fmt?' Error number -10000 occured opening portaudio stream Error message: Host error. Dont know if Im doing it right... I hope some body can help... still being lost in information... more questions will come.... thanx Ivan _________________________________________________________________ Charla con tus amigos en lÃnea mediante MSN Messenger: http://messenger.microsoft.com/es

I got a different version of here http://homepage.mac.com/tigital but it crashes(ver888) when i start the render with a message that the model object is a problem with the error pix_texture: using client storage src/Geos/model_loader.cpp:1164: failed assertion `model' I also got a version from http://taproot.dyndns.org/~cgc/downloads/index.html updated 02/17/04 but that wont start up at all. I t exits with a message dyld: /usr/local/bin/pd Undefined symbols: _btowc _iswctype _mbsrtowcs _towlower _towupper _wcscoll _wcsftime _wcslen _wcsrtombs _wcsxfrm _wctob _wctype _wmemchr _wmemcmp _wmemcpy _wmemmove _wmemset Trace/BPT trap Any ideas?

fft on control data
by charles verron 02 Apr '04

02 Apr '04

Hi list, does anyone know how to take a real time fft on control data stored in a table, as oppose to fft of signal ? I tried the vasp.cfft object, but I can't understand why it takes 2 buffer-name arguments (is the second one assumed to be zero) So if anyone has experience on fft on control data I would appreciate your advice... Thanks -- Charles Verron Charles.Verron(a)la-kitchen.fr La Kitchen

Re: PD-list digest, Vol 1 #1065 - 14 msgs
by Stefan Turner 02 Apr '04

02 Apr '04

Hey, Any chance of some more info on how this might work? Would there be a new object to apply any transformation to vertex positions and colours, or would it be based on getting and setting arrays? I think both could be quite useful, with the 'transform-vertex' (or whatever) object being (presumably) more efficient and ok for simpler stuff, and arrays for anything more complicated. Sorry for all the questions, but this sounds just like what GEM is currently lacking (for my needs). Sorry if any of this has been answered: I haven't been able to find much about it. Cheers, Stefan Message: 14 To: timon botez <timon(a)sosolimited.com> Subject: Re: [PD] Gem .OBJ quest. Date: Fri, 02 Jan 2004 10:13:44 -0600 (CST) From: cgc(a)humboldtblvd.com Cc: pd-list(a)iem.at Hi Per vertex manipulation of models is not possible with the current version of GEM, but I have written a new way of rendering models and 3D objects that will allow exactly this. I was hoping to have it ready to go by the first of the year but that hasn't happened. Look for something in the next few months. cgc Quoting timon botez <timon(a)sosolimited.com>: > Halo, another Gem q. > Does anyone know if there is a way to access the polygons on a imported > > .obj file? > Im drying to distort a model over time and has no idea how to go about > > it. > > Any clues are welcome > HNY > > Timon. > > > _______________________________________________ > PD-list mailing list > PD-list(a)iem.at > http://iem.at/cgi-bin/mailman/listinfo/pd-list > ___________________________________________________________ WIN FREE WORLDWIDE FLIGHTS - nominate a cafe in the Yahoo!

I've been wondering? How do you make PD talk to other programs? Just trying to find which are the preferred methods by the list. I personally prefer OSC, but I know that there are other ways. What do you recommend? Guillermo
