[probly trivial] escaping special character in messages
by Nicola Bernardini 09 Jun '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear list, sorry if this question has already been asked - I did not find much on the archives. How do you escape special characters (i.e. ';' and ',') in messages?

Re: [PD] Using CC (C++) to compile externals

Hi, I cc'd this to pd-dev <pd-dev(a)iem.kug.ac.at> because that's the new list for this kind of questions. Schram, M.J. hat gesagt: // Schram, M.J. wrote: > I want to make a pd-external which makes use of a library which > needs C++. I'm a newbie in writing PD externals.

No, not exactly, but I had to solve similar problems when I ported the dx7 emulator rx-saturno to a PD external (see footils.org). rx-saturno is written in C++, so maybe I have some tips. First I read the Usenet-FAQ on "Howto Mix C and C++" somewhere, that's of help, search google for it. Basically what's needed is: You should use the same compiler for all sources involved. You should define the external's setup function as: extern "C" void something_setup(void) After I discovered flext at http://www.parasitaere-kapazitaeten.net/Pd/ext I wrote most of my externaly directly in C++. ciao, -- Frank Barknecht _ ______footils.org__

The problem of zombies only arises if the process exits, so killing it should not be necessary. Maybe that is the problem under some unixes. Well if someone wants to look at the code, I am starting to setup some CVS repositories which will be used for demudi packageing later. To access it: export CVSROOT=:pserver:anoncvs@devel.demudi.org:/cvsroot cvs co ggee I have included Yves "floating point argument patch" and left my solution to the zombie problem. The setup is not very well tested, so there may be problems. I will add other externals there later, ... Guenter

I need a formula

hi, i'm trying to use a bp~ object so that it can filter frequencies betweem Fmin and Fmax. i think the central frequency should be set to ( Fmin+Fmax )/2, but what value should be given to the Q factor ?? thanx. yves/

GEM OSX is now loading!
by tigital 04 Jun '02

04 Jun '02

yea! ...now I can get down to the REAL stuff! My method for getting it to work requires a bit of a run-a-round, and I'm gonna look into this a bit more, cuz I'm sure there's an easier way to do it, but here it is in a nutshell: All the problems I was having seemed to stem from my attempt to build a dynamic library, using the library template in project builder...I then recalled that one of my older projects had been a mod for Quake 2, and that it was a bundle that was basically used like a shared library, so I made another target similar to the quake2 mod, but retaining the pd/gem-specific things...At first, this didn't work either, but then I looked into the bundle "package" and withdrew the actual library, renamed it Gem.pd_darwin, and then used it to replace the bundle "package" that it was in...I then used "run executable" (previously set up to start pd -lib GEM -verbose), and the whole thing loaded just fine... ...of course, as soon as I tried to open a patch, the whole thing crashed, but it reported what happened very nicely with GDB...anyway, the crash was expected, so now I can start from there... l8r, jamie

hi, thanks to Michael & dan... i've got the answer now. sorry for this real newbie question but i never studied dsp... should i ?? cheers, yves -------- Original Message -------- Subject: Re: [PD-dev] I need a formula Date: Mon, 3 Jun 2002 10:28:26 -0400 (EDT) From: Michael Casey <mkc(a)media.mit.edu> To: Yves Degoyon <ydegoyon(a)free.fr> Center Frequency 0.5 * (Fmax + Fmin) Q factor = ----------------- = -------------------- Bandwidth (Fmax - Fmin) The Heisenberg uncertainty principle dictates that a high Q filter (narrow frequency selectivity) will have low temporal resolution and that high temporal resolution will have low frequency selectivity.

Some progress?
by tigital 03 Jun '02

03 Jun '02

hiya yves (and anyone else who may be lurking)... ...well, I finally managed to get a successful build using ProjectBuilder and the following LDFlags: -bundle -undefined suppress -flat_namespace ...which I just copied from one of the extras examples...weird that it allowed the "-bundle", as opposed to the earlier tries...however, I also didn't include a symbol.exp file: and the following occurred when trying to run pd -lib GEM -verbose: ... tried /Applications/pd-0.35-test23/bin/GEM.pd_darwin and succeeded /Applications/pd-0.35-test23/bin/GEM.pd_darwin: couldn't load GEM: can't load library ... ...I think this means I'm getting somewhere? Seems like it means "I found what you want me to load, but something still isn't quite right"...I'm not sure how to approach this, so any ideas are greatly appreciated! tanx, jamie

? about symbol exports

hi, ...I've been trying to make an OSX port of GEM using Project Builder, which is basically an IDE built around using GCC and GDB...unfortunately, I'm having problems with symbol exports. ...I followed the project builder documentation and made a text file with all of the symbols that I need exported (I think), then added that to the project and did a clean recompile...unfortunately projectbuilder spits this out after some warnings (mostly unused variables, but also alot of "shadow declarations", which I'm unfamiliar with): /usr/bin/jam -d1 JAMBASE=/Developer/Makefiles/pbx_jamfiles/ProjectBuilderJambase JAMFILE=- build ACTION=build _DEFAULT_GCC_VERSION=2.95.2 _GCC3_IS_IN_OFFICIAL_LOCATION=YES BUILD_STYLE=Development CPP_HEADERMAP_FILE=/Users/tigital/Desktop/gem-0.87/src/PBprojects/gem_darwin/build/gem_darwin.build/Gem_d_w-oPart.build/Gem_darwin.hmap SRCROOT=/Users/tigital/Desktop/gem-0.87/src/PBprojects/gem_darwin OBJROOT=/Users/tigital/Desktop/gem-0.87/src/PBprojects/gem_darwin/build SYMROOT=/Users/tigital/Desktop/gem-0.87/src/PBprojects/gem_darwin/build DSTROOT=/tmp/gem_darwin.dst ...updating 8 target(s)...
