externals/build SConscript
by Lorenz Schori 02 Nov '05

02 Nov '05

hi i've done a little work on the SConscript in external build system to better support osx: - define MACOSX for osx builds (for miXed) - remove -dynamiclib from SHLINKFLAGS and add -bundle and - bundle_loader ../../pd/bin/pd - fink and darwinports locations are added to CPPPATH and LIBPATH if they exist - search for *.libs files in win/darwin/linux and after in src directory and add the flags - some few externals still don't compile because of missing libraries and .libs or minor include problems. perhaps we could introduce some static link option (i'm not sure if i'd like statically linked externals). another possibility would be to just grep for the used libraries (*.libs) and bundle them with the externals or with pd.app (not quite trivial. see: http://qin.laya.com/ tech_coding_help/dylib_linking.html). lorenz

[flext] how to call the right setup function
by Georg Holzmann 01 Nov '05

01 Nov '05

Hallo Thomas, list! I have a problem with flext in the following situation: I derive from a class, which is derived from flext_dsp, but should have no setup function, ... example: class A : public flext_dsp { FLEXT_HEADER(A,flext_dsp) [...] // no setup function here } class B : public A { FLEXT_HEADER_S(B,A,setup) [...] private: static void setup(t_classid c); FLEXT_CALLBACK(some_methods_from_A_or_B) }; FLEXT_NEW_DSP_V("B_name",B) void B::setup(t_classid c) { [...] } everything compiles fine, but when I try to load B.pd_linux I get: load_object: Symbol "B_setup" not found Thanks for any hints, LG Georg

class_setfieldnames
by Mathieu Bouchard 29 Oct '05

29 Oct '05

hi everybody, I just added this: EXTERN void class_setfieldnames(t_class *x, const char *s); It's intended to store the names of the fields. What counts as fields and what doesn't is another story. Each struct inheriting from t_gobj has a number of things in it, but I'm especially intending this for messages as found in *.pd files, that is, constructors of objects. By convention I include *every* atom in the creation message, which includes pretty obvious things like "#X obj". What people type in an objectbox starts at argument number 5. (and argument numbering starts at 0). example of use: class_setfieldnames(bang_class, "foo bar x1 y1 class w hold break isa " "snd rcv lab ldx ldy fstyle fs bcol fcol lcol"); where the string is a space-separated list of fields, and in this case it's straight from running desire.tk and typing this in the tcl box: global fields; list $fields(bng) ____________________________________________________________________ Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju Freelance Digital Arts Engineer, Montréal QC Canada

C++ support
by Mathieu Bouchard 28 Oct '05

28 Oct '05

Hi. I have added a new option to the sconsfile. Now if you do this: scons plusplus=1 You get to compile the Pd source code as C++. I've made about a dozen commits to prevent error messages in doing so. There is still some more work to be done here, because it doesn't fully compile yet. This initiative is only so that we have more doors open for the future. I currently have no plans to use C++-specific things in devel, DesireData or not. ____________________________________________________________________ Mathieu Bouchard - tél:+1.514.383.3801 - http://artengine.ca/matju Freelance Digital Arts Engineer, Montréal QC Canada

How to initialise array?
by Ed Kelly 27 Oct '05

27 Oct '05

Hi all, Please excuse my lack of knowledge, but I am truly stuck. I'm having trouble with this external I've written. Basically it needs to initialise an array as it is loaded, so that when audio is turned on it starts an array-FIFO process where one array calculated from the input vector is stored in another on each block. I tried putting a for loop in the _new function, and this works when the object is loaded from within a PD patch. But when I try to load the patch again it crashes PD. Does anyone know of a command that initialises an array to zeros? I will I have to make a workaround?

interactive video interface for windows
by Colin Gilboy 20 Oct '05

20 Oct '05

Hi PD-Dev list. This is my first post. Welcome me, heartily. I'm working on a webcam motion-detection based external for pd in windows. Right now I have a video detection module that runs in python and connects to a lightweight socket communication external in pd. The idea is that the user can define little regions (via pd) in the webcams field of vision (at this point, rectangles) and if the python side detects motion in those regions, it spits out the id number of that particular region in the pd external. that way particular regions can be mapped (via select, moses, whatever...) to some actions in pd. It works, but it's bulky because it requires python. I believe a similar system exists in PDP, but as far as I understand, that doesn't work in windows, and my webcam doesn't get along with linux. I'm pretty sure I can get this whole system to work purely in C/C++ and run directly through the pd external, but I haven't been that ambitious yet (python's so nice for prototyping). Is it worth the effort? Otherwise, anyone have any comments, tips, direction? Thanks, colin

audio api settings
by Tim Blechmann 20 Oct '05

20 Oct '05

hi miller, is it intended that the audio devices are disabled by default? i think the behaviour of "pd -jack -channels 2" should be, that jack is opened with 2 input and 2 output channels and both input and output are be enabled ... cheers ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

REALLY_POSIX_MEMLOCK
by Tim Blechmann 20 Oct '05

hi miller, i'm not sure, why you introduced REALLY_POSIX_MEMLOCK ... what's wrong with: #if (_POSIX_MEMLOCK - 0) >= 200112L as it's in devel for some time now? cheers ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

more .net dev questions
by Conor 20 Oct '05

20 Oct '05

Hi folks, I was hoping to begin tinkering around some of the source to pd using visual studio.net as the ide. Does anyone have by any chance some dsw/.sln to share with me so as i do not have to go through the make script on construct the dsw by hand! Are there any unusually build requirements? Best regards, Conor
