Sending list of floats out an outlet
by Ben Bogart - FMPM/F1999 16 Jul '02

16 Jul '02

I want to calculate a series of floats and output them as a list out the outlet, I see: void outlet_list(t_outlet *x, t_symbol *s, int argc, t_atom *argv); but don't know how to set the contents of the list, ie I'm not sure how to use gensym("list"). Thanks Ben B. Bogart ---------

width of graphical representation
by Philip Stolz 14 Jul '02

14 Jul '02

I've written an external that generates a variable amount of outlets in its new-method. The amount is dependent on a number specified in the external's object box at creation time. Typically I need up to 16 or even more outlets. Since only textwidth is considered for the width of the graphical representation (object box) of my external, I can't distinguish more than 8 (hardly distinguishable) outlets displayed. Has anyone an idea, how the width of an object box can be specified or changed in the new-method? Thanks in advance, Phil.

GEM-0.87b2 OS X released!
by tigital 11 Jul '02

11 Jul '02

get it at: http://homepage.mac.com/tigital ...and here's what's new: --------------------------------------------------------------------------- beta2 release: - resizing window now works with [dimen x y] message before window creation [dimen 500 500] is default - profiling is off by default ([profile 0]) - compiler optimization is level 3 (ie. everything's much faster!) - window double buffering is default; can be changed to single buffering by [buffer 1] message to gemwin (thanks for pointing this out Ben!) --------------------------------------------------------------------------- I also finally figured out how to correctly build the external in project builder without all the "un-packaging" hassles...so what? well, this was the major reason I hadn't released the source, which means we're really close to the source release, so iohannes, get that CVS ready! Also, I'm interested in any example patches, especially complex patches that would really give the port a workout... ;-) jamie

Hey all, How are people developing under OSX? using the command line or IDE? Anyone developed a working makefile for OSX externals? Thanks! Ben B. Bogart ---------

Re: [PD] tiny gcc 3 compile problem
by Krzysztof Czaja 09 Jul '02

09 Jul '02

hi, since this is my patch (the htons call), I am the one to blame... I am not sure why this code is undefined -- it is probably the new -Wsequence-point warning introduced in gcc 3.0, although there _is_ a sequence point between pre-incrementation and a function call (unless htons is now a macro, not a function call)? How about gcc 3.1?

GEM-0.87b1 for OS X released
by tigital 09 Jul '02

09 Jul '02

http://homepage.mac.com/tigital ...like the subject line says: it's not finished (what is?), but it's at a spot where I think people can start learning/experimenting...no source yet, far too much ugly debug stuff in there now, and I want to do a major change to how the film/movie's are loaded (mac side only)... ...also, I'm building this in Project Builder as a bundle. Unfortunately, pd won't load it as a bundle: right now I have to open up the bundle and navigate to the 'executable/library', then pull it out and place it in the same place that the bundle is, then delete the bundle and finally rename the moved library "GEM.pd_darwin"...this then is loaded just fine by pd (btw, I'm using pd-0.35-test29)...anyone have an idea how to get around this/do it correctly? I figure that the source and project builder stuff should wait to be released when this is worked out... oh, and here's some stuff from my first attempt at a readme...start banging away and send me some bug reports! enjoy, jamie -------------- beta1 release: - Place GEM.pd_darwin in your pd-0.35-testX/extras folder - To run pd with GEM, add "-lib GEM" to your command for pd ie: /Applications/pd-0.35-test29/bin/pd -lib GEM - The default graphics window is at [offset 0 0]...you can change this in any patch by adding a message to [gemwin] for [offset x y] - The graphics window is defaulted to 500x500 on the main monitor: the dimensions can be changed, but I haven't made it aware of multiple monitors (yet), or fullscreen for that matter... - pix_imageInPlace doesn't seem to work - 3d font/text isn't implemented yet... - when using pix_movie or pix_film, you can load *.mov or *.mpg, but the *.mpg will crash, because it can't tell the # of frames or framerate yet...*.avi's won't load if they are in Indeo compression - *.obj 3d models load, but only do this after a window has been created. There are several examples that use a [loadbang] to load everything on opening the patch, but we need an OpenGL context to do this on the mac, which means you need to open a graphic window before you can load a model... - particles seem to work fine - no saving of images/movies yet - no video input yet (soon!) - mouse, tablet, and orb input aren't working - Remember, this is a debug version, so there's lots of output to the console about what's going on, and no compiler optimizations are on

Trouble compiling under OSX
by Ben Bogart - FMPM/F1999 04 Jul '02

test 29, OSX 10.1.5 tcl/tk MacOSXtk8.4a4-2 (from sourceforge) HW Single G4-733 ./configure fails with: -I/Library/Frameworks/Tcl.framework/Versions/Current/ Headers -I/Library/Frameworks/Tcl.framework/ Versions/8.4/PrivateHeaders -c -o ../obj/t_tkcmd.o t_tkcmd.c /Library/Frameworks/Tk.framework/Versions/Current/ Headers/tk.h:86: header file 'X11/Xlib.h' not found ... /Library/Frameworks/Tk.framework/Versions/Current/ Headers/tkDecls.h:1084: undefined type, found `GC' /Library/Frameworks/Tk.framework/Versions/Current/ Headers/tkDecls.h:1086: undefined type, found `Pixmap' /Library/Frameworks/Tk.framework/Versions/Current/ Headers/tkDecls.h:1087: undefined type, found `XColor' /Library/Frameworks/Tk.framework/Versions/Current/ Headers/tkDecls.h:1091: undefined type, found `Pixmap' cpp-precomp: warning: errors during smart preprocessing, retrying in basic mode make: *** [t_tkcmd.o] Error 1 Looks like there are still X11 calls in the OSX version? Any ideas? I'll soon be teaching a PD class at a facility with mostely Macs, hoping to get it to work here at work first. I can run test26 precompiled, but The audio does not open due to: using input device -1 using output device 0 nchan 2, flags3, bufs 8, framesperbuf 256 Error -9999 occured opening portaudio stream Error Message Invalid number of channels. I also tried running it with 1,3,4 channels, no change. The precompiled stuff works fine on the Dual 450 running 10.1.0 (as I just discovered) so its only the Single 733 "quicksilver" which is giving me problems. Thanks Ben

passing symbol arguments to a method
by Ben Bogart - FMPM/F1999 02 Jul '02

02 Jul '02

Hello all, I'm trying to build a PD method for this SDL function: SDL_Surface *IMG_Load(const char *file); problem is I can't figure out how to pass the symbol argument as a filename which IMG_Load expects. Here is my current method: void load_images(mystruct *x, t_symbol* image1_src, t_symbol* image2_src) { /* Symbol pointer stuff */ image1 = IMG_Load( (char *) image1_src ); if (image1_src == NULL) { post("Image 1 could not be opened"); } image2 = IMG_Load( (char *) image2_src ); if (image2_src == NULL) { post("Image 2 could not be opened"); } SDL_Flip(screen); } Which results in a segfault. I tried it without typecasting but gcc just complains that its the wrong pointer type. class_addmethod(myclass, (t_method)load_images, gensym("open"), A_DEFSYM, A_DEFSYM, 0); I also tried using argv and atom_getsymbol() with the same pointer-type porblem. What am I doing wrong? Thanks Ben B. Bogart ---------
