OSX compile problem
by Joshua McFadden 28 Sep '02

28 Sep '02

Hello, all! After a bit of a dormant period, I'm trying to get pd to compile on my OSX box (10.2, all recent updates as far as I know). I get this problem when I try to compile: cc -DPD -DUNIX -Wall -W -Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno-switch -O2 -DMACOSX -I/usr/X11R6/include -I../portaudio/pa_common -I../portaudio/pablio -I../portaudio/portmidi-macosx -Wno-error -DINSTALL_PREFIX=\"/usr/local\" -I. -c -o ../obj/g_text.o g_text.c /usr/include/architecture/ppc/math.h:440: too many args (1) to macro 'cabs' (0 expected) cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode make: *** [g_text.o] Error 1 I'm totally baffled about that header file - the complex abs macro 'cabs' _does_ take an argument: [lasa:~/runtemp/pd-0.35-0/src] josh% grep cabs /usr/include/architecture/ppc/math.h extern double cabs ( _complex z ); Is there something else that's wrong? The only caveat I can find for OSX is that I need to have Tcl installed - I have it in two different places. :) Anybody have a suggestion? Thanks!! -- Joshua McFadden http://mindsound.org/

RE: [pd] cellular automata

:Hi, :If you're on windows, check out Framestein (http://framestein.org), :it's 2D, has an implementation of Conway's Game of Life to get you :started... I'll send you more info on it if you like. :cheers :Juha Great. I haven't gotten a chance to really look at framestein in depth but now i will try. The game of life patch should be very helpful. (of course, before i even get started coding i'm thinking back towards GEM and how it would be so fun to make it 3d and have all the cubes spin around on differenet axis' etc. but now im ahead of myself) thanks, walter carpenter

cellular automata with pd
by wwcarpen 26 Sep '02

26 Sep '02

Hello everybody. I've been interested in doing some experiments with cellular automata scpecifically visual but maybe i could journey into different controls for sound and composition as well. I'm interested in starting simple, and then seeing where i could go with it, but i don't know quite where to begin. I'm thinking GEM is what i want to use here for my output. what is the best way to set up a grid to have the fill of the blocks alternate their color according to rules? I don't have much expirience with coding so i get hung up on the most effective way to do it. Maybe someone has started a framework like this i could take a look at? Also I'm thinking that maybe there is a simpler way of outputing the graphics, because all I want is 2D for now. I thought about using plain text symbols in the console window but that isnt really elegant enough, and the data structures always seem to get unstable on my machine when the patch becomes complex (i guess this could be poor coding on my part) anyway. thanks for any info, walter carpenter ps, in the time I took attempting to send this message (long, pointless story..) i did find the cellular automata external that comes with maxlib. I think it will help me out a lot, although it still doesnt explain how i should go about setting up a basic array for the visual output.

:you could just set up a grad of Gem squares in one plane and send thier :individual colour values from your CA stuff... simple enough? :Ben Ok, I guess it can't be that difficult. I'm just concerned I'm going to make a really messy patch if i wanted to make say, a 1024x768 grid, but i guess i'm just going to have to expiriment to see how to do it most efficiently. thanks, walter carpenter

DirectSound buffers
by MLN Kazem, Aerospace Engineering 25 Sep '02

25 Sep '02

Hi List, Any hints on where I find the following info? On windows platforms does/ can pd use DirectX - does/can pd create DirectSound secondary buffer objects and can these be accessed before they are mixed in the primary (if they are at all) - would the usage of DirectSound cause real-time problems? am I missing the point of pd? thanks Mandana ---------------------- MLN Kazem, Aerospace Engineering M.Kazem(a)bristol.ac.uk Tel. 0117 9288219 Fax. 0117 9272771

GOP positions
by marius schebella 25 Sep '02

25 Sep '02

hi, i mentioned a problem some time ago, which is really annoying for me, that is that if i open a patch, its size gets bigger by two pixels. (and also is opening with at least 247*46 pixel). this is destroying the positioning of objects of a graph on parent-window. ok some of my GOPs are intended to be smaller, so whenever i make a change within it, i have to correct the size in an editor... but there is also another problem: some of the objects are shifted by one pixel, which could be the result of a rounding-error... and i found that the gop-size properties are saved in a line like "#X coords 0 0 1 1 123 23 1;". but that doesnot fit together with the very first lin #N canvas ..." respectively if both values are equal, still the GOP doesnot look equal. thank you for your patience. marius.
