PATCH: one-liner for linux with multiple audio cards

I think we should try to find a way to avoid nameclashes! Taking the above example, someone might only be using the maxlib library and thus [gauss] is perfectly allright. Let's say someone else is running Pd with footils library, there one would get gauss from footils... Not what we want, I guess! On the other hand, I think, it would be rather easy to implement a mechanism that tell's pd from which library to load an object from when typing [libraryname.objectname]. This could be used to force Pd to use gauss from maxlib, not from footils in case both are present. But, right, this makes object boxes much longer. BTW, what does Pd right now if there are two identical objects? Does the one win that is loaded into Pd first? (I gues the order is Pd core objects -> libraries -> single externals -> abstractions ?) > I'm not sure, > how a "using namespace maxlib" could be implemented or be useful in > the PD programming language. We allready have a similar thing when specifying which library to load. I don't see any differences here. I think the best - and most difficult to implement - way would be to create objects as usual but to save information about the libraries / namespace (invisibly) in the pd patch. In case one of the libraries is missing on another machine, one would get an error message instead of an object from a wrong library. But then we still need a mechanism to force Pd to use a special library. Olaf

sending data to Pd with UDP
by Floris Groen 12 Aug '02

12 Aug '02

Hi, I'm quite new to this whole Pd thingy. I'm trying to send data to Pd over the network using winsocket and UDP, but it doesn't seem to work. When I tried receiving stuff from Pd then it did work. Basically I'm just sending a character array using the winsocket sendto function. Does anyone know how to get this to work?

gem-related libraries, runtime errors
by Artem Baguinski 12 Aug '02

12 Aug '02

hello i'm trying to make a gem package for gentoo GNU/Linux distribution. compiling it following instructions in src/Gnu/README.build was no problem. but on ftp there were some more packages, which i dont know what to do with. they ain't mentioned in the README.build, but it seems (i tried some examples) they are quite useful. to make a package i'd rather know in what order should i build these other packages [and what are there, where they came from etc]. i also read in the mailing list archive about libmpeg3 dependancy, it isn't mentioned in the document either. i have pd/gem installed on my debian machine and there they work absolutelly perfect (but they are older versions also). on gentoo machine gem generates lots of errors and sometimes "misbehaves". example: ============================================================ reading startup file: /home/buggs/.pdrc GEM: Mark Danks GEM: ver: 0.84-5 GEM: compiled: Aug 11 2002 >>> here i open a patch (red square) >>> then click on create error: GEM: Unable to create single buffer window error: GEM: Error creating const context error: GEM: A serious error occured creating const Context error: GEM: Do not continue! GEM: window created >>> i click 1 GEM: Start rendering >>> everything seems to work alright >>> then i click 0 GEM: Stop rendering >>> and finaly destroy... Segmentation fault pd_gui: pd process exited >>> hmmm.... seems it understood me literally :) ============================================================ pd/gem segfaults every time i do destroy and complains about creating single buffer window and context. i have a feeling this two are related... do simptoms look familiar to anybody? thanks. -- Artem Baguinski (http://www.artm.org/) V2_Lab - International Lab For the Unstable Media (http://www.v2.nl/V2_Lab/) Eendrachtsstraat 10 - 3012 XL Rotterdam

I read: > BTW, what does Pd right now if there are two identical objects? there is noc such thing as two identical objects once [name~] is loaded all references to it will call name_tilde_new() pd will simply not try to load another object (or abstraction) wiht that name. > Does the one win that is loaded into Pd first? of course see above > (I gues the order is Pd core objects -> libraries > -> single externals -> abstractions ?) no the order is the order of your path and lib flags (of course the core objects will always be there since they are loaded at startup) and (at least for abstractions) . comes first in the search path) regards, x -- chris(a)lo-res.org Postmodernism is german romanticism with better http://pilot.fm/ special effects.

readsf¬, writesf¬

Thanks, Marius. Thanks, Olaf: - The standard PD Objects readsf¬ and writesf¬ are marked like "only UNIX" - How must be installed the Sfio.zip? How must being distributed the files among the PD folders (in Win 98)? Whit which keys can be typed this strange tilde like readsf¬ who needs the audio objects? --------------------------- > Hi, > > you should use readsf~ and writesf~ (standard Pd objects), but there's also a windows port if sfread~ / > sfwrite~ available: > > http://www.akustische-kunst.org/puredata/winport/sfio~.zip > > Olaf > > salvador mestre schrieb: > > > hello everybody...I have win 98.
