hi i seem to be having some trouble making a simple example to display the output of a division of 2 integers. it seems that PD is reporting inaccurate calculations for reasons unknown to me. i was hoping that if i send the patch to this list i could possibly get help in understanding what it is i do incorrectly. thanks. #N canvas 328 200 593 299 10; #N canvas 0 0 595 418 guts 1; #N canvas 0 0 450 300 graph1 0; #X array array1 12 float 3; #A 0 1 2 3 4 5 6 7 8 9 10 11 12; #X coords 0 0 12 12 200 140 1; #X restore 336 72 graph; #N canvas 0 0 450 300 graph1 0; #X array array2 12 float 3; #A 0 1 2 3 4 5 6 7 8 9 10 11 12; #X coords 0 0 12 12 200 140 1; #X restore 336 254 graph; #X msg 41 40 \; array1 0 1 2 3 4 5 6 7 8 9 10 11 \; array2 0 1 2 3 4 5 6 7 8 9 10 11; #X obj 70 237 tabread array1; #X obj 68 341 tabread array2; #X obj 70 263 s array1-disp; #X obj 68 369 s array2-disp; #X obj 84 125 metro 2000; #X obj 84 167 random 12; #X obj 164 167 random 12; #X obj 206 342 /; #X obj 206 372 s result; #X obj 84 98 inlet; #X obj 41 17 loadbang; #X obj 206 276 r array1-disp; #X obj 222 307 r array2-disp; #X connect 3 0 5 0; #X connect 4 0 6 0; #X connect 7 0 8 0; #X connect 7 0 9 0; #X connect 8 0 3 0; #X connect 9 0 4 0; #X connect 10 0 11 0; #X connect 12 0 7 0; #X connect 13 0 2 0; #X connect 14 0 10 0; #X connect 15 0 10 1; #X restore 18 377 pd guts; #X obj 76 53 nbx 2 45 -1e+37 1e+37 0 0 empty array1-disp empty 0 -6 0 72 -262144 -1 -1 4 256; #X obj 74 151 nbx 2 45 -1e+37 1e+37 0 0 empty array2-disp empty 0 -6 0 72 -262144 -1 -1 6 256; #X text 61 119 --------------------------; #X text 289 119 =; #X obj 338 105 nbx 8 45 -1e+37 1e+37 0 0 empty result empty 0 -6 0 14 -44926 -1 -1 0.444444 256; #X obj 18 356 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 1 1 ; #X text 39 355 <- start; #X connect 6 0 0 0;

externals
by Chuckk Hubbard 11 Aug '06

Is http://pure-data.sourceforge.netstill updated? I just made zexy from it and found it doesn't have [operating_system]. I'll try again with zexy from ftp://iem.at/pd/Externals/ZEXY . Although I don't see any record of OS being added in the release notes... -Chuckk -- "Far and away the best prize that life has to offer is the chance to work hard at work worth doing." -Theodore Roosevelt

Re: [PD] PD markov object

Please tell us a bit more about your problem. Yes, my apologies. I'm using cygwin. It seems that the makefile is tailored only to linux, and my goal is to compile a .dll for windows. At first the compilation itself failed with lots of "undefined reference to ..." that quickly scrolled off the dos window (why can't they put a scrollbar on it?!). I tried hacking the makefile, and now it compiles to the *.o files OK, but the linking still failes with a similar multitude of "undefined reference" errors, all things to do with pd, like "outlet_float," etc. I've pasted the makefile below. I understand that the problem is with includes and libraries, but I haven't find a solution. Any clues (or a working makefile!) are appreciated :) -Chris (makefile) current: all # This makefile is a ripoff of the zexy lib makefile # by johannes m. zmoelnig (thanks, johannes :-) # mahash/mapwrite/mapread makefile # everything is GnuGPL that should come with the object # make sure that the "m_pd.h" is somehow available either by putting it into this # directory, by adding it's path to the INCLUDE-path or by putting it into an # already included path, e.g. "/usr/local/include/" #these are the user adjustables : adjust them to fit into your system # PD will install to $(DESTDIR)$(INSTALLL_PREFIX)$(PDLIBDIR), which is /usr/local/lib/pd # by default DESTDIR = INSTALL_PREFIX = /cygdrive/c/WINDOWS/Desktop/pd-0.38-4/pd-0.38-4-devel-2 PDLIBDIR = /lib INSTALLDIR = /externs HELPFILEDIR = /doc/5.reference #these were the user adjustables TARGETS = dice in_out markovUtils rb_tree buffer dice2 fileio markov rand table # ----------------------- LINUX ---------------------------- .SUFFIXES: .pd_linux LINUXOBJECTS = $(TARGETS:%=%.o) ARCH = $(shell uname --machine) PD_DIR = $(DESTDIR)$(INSTALL_PREFIX)$(PDLIBDIR) ifeq (${ARCH},alpha) AFLAGS = -mieee -mcpu=ev56 endif LINCLUDE = -I/usr/include -I/cygdrive/c/WINDOWS/Desktop/pd-0.38-4/pd-0.38-4-devel-2/src $(LINUXOBJECTS): *.h CFLAGS = -O2 -g -Wall $(LINCLUDE) $(UCFLAGS) $(AFLAGS) \ -DPD -O2 -funroll-loops -fomit-frame-pointer \ -W -Wshadow -Wstrict-prototypes \ -Wno-unused -Wno-parentheses -Wno-switch everything: clean all install distclean install: # cp maphash.pd_linux $(PD_DIR)$(INSTALLDIR) # cp maphash-help.pd $(PD_DIR)$(HELPFILEDIR)/maphash.pd # cp maphash-io.pd $(PD_DIR)$(INSTALLDIR) # cp maphash-io-example.txt $(PD_DIR)$(INSTALLDIR) # ln -s $(PD_DIR)$(HELPFILEDIR)/maphash.pd $(PD_DIR)$(HELPFILEDIR)/mapread.pd # ln -s $(PD_DIR)$(HELPFILEDIR)/maphash.pd $(PD_DIR)$(HELPFILEDIR)/mapwrite.pd uninstall: # rm $(PD_DIR)$(INSTALLDIR)/maphash.pd_linux # rm $(PD_DIR)$(INSTALLDIR)/maphash-io.pd # rm $(PD_DIR)$(INSTALLDIR)/maphash-io-example.txt # rm $(PD_DIR)$(HELPFILEDIR)/maphash.pd # rm $(PD_DIR)$(HELPFILEDIR)/mapread.pd # rm $(PD_DIR)$(HELPFILEDIR)/mapwrite.pd distclean: touch dummy.o touch dummy.pd_linux touch dummy~ touch _dummy rm *.o *.pd_linux *~ _* clean: touch dummy.o touch dummy.pd_linux rm *.o *.pd_linux all: $(LINUXOBJECTS) @echo :: $(LINUXOBJECTS) ld -L/cygdrive/c/WINDOWS/Desktop/pd-0.38-4/pd-0.38-4-devel-2/lib -export_dynamic -shared -o markov.dll *.o -lc -lm strip --strip-unneeded markov.dll .c.pd_linux: gcc $(CFLAGS) -O2 -DPD -fPIC $(INCLUDE) -c -o $*.o $*.c (end makefile)

Multiple (same) instances, and [sssad]
by Tas Pas 10 Aug '06

10 Aug '06

Hi list, I have a patch that features the same abstraction many times. Each one of these abstractions are connected to different objects so they do other things each. Now, trying to intergrade a snapshot feature to my patch, using the [sssad] object, I came to a problem with the abstractions: I opened each one within the patch and added the [aaasd xxx] object. When I save them all the same abstractions had the [aaasd xxx] object, which made my state load difficult (all the abstraction's setting are the same). Can pd load each abstractions the object oriented way? Each abstraction to have it's set of properties? If not, do I have to set for each of my abstraction outlets for their settings?

OT: collectives in america?
by Kevin McCoy 10 Aug '06

10 Aug '06

Hello everyone, I've been enjoying looking around the sites of different groups/events in Europe that have formed around free software (Pd in particular), like APO33, OpenLab, goto10, etc... are there any that are operating in the U.S.? I just haven't come across any yet. Or Japan? Thanks for any info! Kevin

pd crashes jackd
by Ben Saylor 10 Aug '06

10 Aug '06

I've been having this problem for quite a while... whenever I quit PD, jackd crashes after a few seconds. Looking in the Connections window in qjackctl, I can see that PD's ports remain after quitting until the crash. If I run jackd in the terminal with the same command as qjackctl runs (jackd -R -P89 -t10000 -dalsa -dhw:0 -r44100 -p128 -n2 -P -S) , its last words are: jackd watchdog: timeout - killing jackd I'm running Debian testing, jackd 0.101.1-1, Pd-0.39.2-extended-test4, but this has been happening for several PD versions (not sure when it started). Is anyone else seeing this? One other jack app I know of, jack-rack, actually has the same problem. Ben

array copy speed test
by Hans-Christoph Steiner 10 Aug '06

So I did a little speed test between C and Pd for doing an array-to- array copying. Pd didn't fair so well. Can anyone thing of a better algorithm for copying in Pd? .hc

That is another solution ofcourse, but it would be way more > practical to have only one text file and one qlist object. How about using arrays in data structures to sequence? I seldom use qlist because this is more versatile. If you pack all the important data for each step of a sequence into an element of an array, you can call up any step easily, as many times as you like. I made a quick example patch. It takes a little more patching than a qlist, but, if I understand correctly, it does exactly what you want. Does this help? -Chuckk
