Problem with the error function
by Pierre Guillot 21 Feb '21

21 Feb '21

Hello, There is a crash on Linux version of Camomile when an attempt to read a file that doesn't exist with the [textfile] or [text define] objects ( https://github.com/pierreguillot/Camomile/issues/239). After some investigation, it seems that the call of the error() function from the binbuf_read_via_canvas() function generates the crash ( https://github.com/pure-data/pure-data/blob/eeef4ba9130d3182146927c37fa57d6…) - if I remove this line, the problem is fixed. I tried to find the problem with this error() function and I realised that this Pd error() function might not be used in fact (because if I remove all the content of this error() function and so it doesn't do anything, the program still crashes). I can even remove the definition of the function ( https://github.com/pure-data/pure-data/blob/eeef4ba9130d3182146927c37fa57d6…), the plugin still compiles! So I think that there is confusion and another function is used instead of the Pd one from s_print.c. t could be this function ( https://man7.org/linux/man-pages/man3/error.3.html) from error.h but I can't find where this header could be included. First of all, is my assumption (the confusion between two functions with the same name) plausible? If so, do you think it could be the one from error.h? And can I fix this? If you want to test, I suggest you use the dev/cmake-support branch of Camomile that is pretty easy and straightforward to compile and the VST3 plugin. Thank you for your assistance! All the best, Pierre

Using Pd on macOS with Tcl/Tk installed via Homebrew
by Dan Wilcox 05 Feb '21

05 Feb '21

Howdy all, Just a quick note that I tested running Pd from the command line using a newer version of Tcl/Tk installed via the Homebrew package manager. Works fine, Tk Wish 8.6.11 on macOS 11.2. You mainly need to make sure the right wish app is invoked and *not* the old buggy version which comes with the system. For testing, I used: /opt/homebrew/opt/tcl-tk/bin/wish8.6 ~/src/pure-data/tcl/pd-gui.tcl If you add /opt/homebrew/opt/tcl-tk/bin to the start of your PATH, then Pd would use the alternate install automatically. Anyway, one more step towards being able to build & install Pd to the system via Homebrew. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Re: [PD-dev] [PD] soundtouch~ for Pd Vanilla

I took liberty of moving this to pd-dev. On Wed, 2021-01-27 at 22:59 -0300, Alexandre Torres Porres wrote: > It's only missing binaries for windows64 bits, linux64 bits and > raspberry pi versions.

It seems my version of g++ (9.3.0) doesn't accept double-dash flags (anymore?). For it to compile on amd64, I had to add '-fPIC' to LINUXCFLAGS. It compiles without error then, but loading the binary crashes Pd: ~~~ $ pd -open soundtouch~-help.pd pd: AAFilter.cpp:107: void soundtouch::AAFilter::calculateCoeffs(): Assertion `length >= 2' failed. Pd: signal ~~~ On armv7, I had to remove '-msse' from LINUXCFLAGS for it to compile. The resulting binary loads fine in Pd, but I hadn't a chance to really test it, because I don't have sound on that machine. Roman

Cross compiling for windows from mac
by Eric Lennartson 28 Jan '21

28 Jan '21

Hey everyone, I've been using pd-lib-builder and make as my build system for compiling my library. I have a very basic understanding of make and compilers, so it's mostly been a monkey see, monkey do affair, where I look at other peoples makefiles to understand how to get things to happen. So I have two questions. A. How do I cross compile for windows from mac using pd-lib-builder and make? B. If someone cloned my repo to their windows machine, what would they need in order to compile using pd-lib-builder and make? Thanks, Eric

Object for getting array values when you're clicking on it and changing it.
by Alexandre Torres Porres 24 Jan '21

24 Jan '21

Hi, if I need my mouse interaction on a table to immediately affect controls of my patch (think of it as some sort of multislider or whatever), what I do is have a metronome getting values from it at a reasonably high rate with [array get]. That is far from ideal, this is why I want to design a new [buffer] object that outputs values from tables/arrays when you click on it and change them. Any idea, hints or clues on how I could do that? And is there an interest that a new function in [array] could do that? cheers

Using pd_bind and pd_findbyclass to access data from another external
by Eric Lennartson 20 Jan '21

20 Jan '21

Hello all, I've been working on trying to send data between different externals, but I'm not doing something quite right. I've looked at the code in d_global.c as well as for send and receive. The only difference I can see is that mine is not all in the same .c file while in the pd source it is. Here's the external with the data. Just an int for now, but it will be holding a binary tree later. static t_class *send_test_class; typedef struct _send_test { t_object x_obj; t_symbol* name; int value; }t_send_test; static void *send_test_new(t_symbol *s, t_floatarg f) { t_send_test *x = (t_send_test *)pd_new(send_test_class); x->name = s; x->value = f; pd_bind(&x->x_obj.ob_pd, s); // bind to the name we're given post("send_test created with name %s, and value %d", x->name->s_name, x->value); return(x); } static void send_test_free(t_send_test *x) { pd_unbind(&x->x_obj.ob_pd, x->name); // unbind when deleted } void send_test_setup(void) { send_test_class = class_new(gensym("send_test"), (t_newmethod)send_test_new, (t_method)send_test_free, sizeof(t_send_test), CLASS_NOINLET, A_DEFSYM, A_DEFFLOAT, 0); } And here's the receiver. static t_class *send_test_class; static t_class *rcv_test_class; typedef struct _send_test { t_object x_obj; t_symbol* name; int value; }t_send_test; typedef struct _rcv_test { t_object x_obj; t_symbol* name; int value; } t_rcv_test; static void *rcv_test_new(t_symbol *s) { t_rcv_test *x = (t_rcv_test *)pd_new(rcv_test_class); x->name = s; t_send_test* sender = (t_send_test*)pd_findbyclass(x->name, send_test_class); x->value = sender->value; post("sender value is %d", sender->value); post("rcv_test created with name %s, and value %d", x->name->s_name, x->value); return(x); } static void rcv_test_free(t_rcv_test *x) {} void rcv_test_setup(void) { rcv_test_class = class_new(gensym("rcv_test"), (t_newmethod)rcv_test_new, (t_method)rcv_test_free, sizeof(t_rcv_test), CLASS_NOINLET, A_DEFSYM, 0); } What exactly is it that I'm doing wrong?

Threaded I/O for Pd
by Giulio Moro 18 Jan '21

18 Jan '21

Hi there, I created a PR that implements threaded I/O for Pd's GUI and netsend/netreceive objects. The objective is to have the audio thread free of select()s and locks wherever possible ("best effort RT-friendly"). Our Bela users have been using libpd with previous versions of these commits for almost 5 years and I thought it was about time to try and upstream the changes. It's my first big PR submission for Pd, so I am looking forward to your comments. Details in the PR: https://github.com/pure-data/pure-data/pull/1261 Kind regards, Giulio

building fluid~ on Linux (was: [PD] fluid~ for Pd-Vanilla - test version)

I just updated pd-fluidsynth repo to get your and Lucas' most recent changes. I didn't have to modify anything for the build process to work. ~~~sh cd pd-fluidsynth make pkglibdir=$HOME/pd-src/workspace/Linux-arm7-32 make pkglibdir=$HOME/pd-src/workspace/Linux-arm7-32 install cd $HOME/pd-src/workspace/Linux-arm7-32/fluid~ sh linuxdep32.sh rm linuxdep32 ~~~ However, the crucial part is that the included libfluidsynth.so should not be "tainted" with support for all kinds of things. This means, you can't take the one shipped by the distro. > Can you describe the steps and put it in our readme (with a PR)? You mean what steps were necessary to compile fluidsynth? I didn't have to do anything suprising or special. I just had to figure out how to disable everything by reading the docs about building. This is what I came up with (I hope it is correct and complete): ~~~sh git clone https://github.com/FluidSynth/fluidsynth/ cd fluidsynth mkdir build cd build cmake -Denable-libsndfile=off -Denable-jack=off -Denable-alsa=off -Denable-oss=off -Denable-pulseaudio=off -Denable-ladspa=off -Denable-aufile=off -Denable-network=off -Denable-ipv6=off -Denable-getopt=off -Denable-sdl2=off .. make sudo make install ~~~ After this, I compiled fluid~ with steps from above. Regarding the makefile of pd-fluidsynth, I don't understand the purpose of this section: --- define forLinux ifeq ($(firstword $(subst -, ,$(shell $(CC) -dumpmachine))), i686) datafiles += scripts/linuxdep32.sh else datafiles += scripts/linuxdep64.sh endif endef --- Depending on which arch is detected, it'll add one or the other script in the build result. I think what this is meant to do is to _execute_ the arch specific script, so that libraries get included. I'm not yet familiar with makefiles to tell you just right away how this is done, but according to the snippet, I'd suppose something like this: --- define forLinux ifeq ($(firstword $(subst -, ,$(shell $(CC) -dumpmachine))), i686) $(shell /bin/sh scripts/linuxdep32.sh) else $(shell /bin/sh scripts/linuxdep32.sh) endif endef --- In order to include the additional dynamic libraries, you'd add 'libfluidsynth.so*' to 'datafiles'. However, the above detection fails for arm7 and it'll wrongly executes scripts/linuxdep64.sh. I think instead of an if-else, it could detect the arch and execute the appropriate script with arch in the name. If the scripts for several archs turn out to be the same, they could be symlinked. Just an idea. Another thing about scripts/linuxdep*.sh script. I think they should call cp with the -d flag. Without it, it creates three full copies of the same .so file. With -d symlinks are preserved. I realize it's a lot of suggestions. Sorry for that. So maybe a PR would be easier for you to digest. Thing is I don't feel yet sufficiently confident with these matters, but am happy to learn. Roman

Releasing to deken
by David Rush 06 Jan '21

06 Jan '21

Hi - So during lockdown here in Ireland, I bought a Sensel Morph to try and improve my PD performance abilities. I love the device, and very quickly graduated to trying to work with its MIDI MPE capabilities. This rapidly led me down the road to writing an an external [mpoly] object to handle the variety of messages that need to be dispatched for MPE. Having become frustrated with limitations in Sensels MIDI mapping software, I then proceeded to write a series of external objects that use the Sensel device API to directly communicate with PD. And it all seems stable enough to release, but I'm a bit hazy on some aspects of publishing to deken, and was hoping someone could either answer my questions or point me to an appropriate document (as these questions haven't been addressed in anything I have found so far). 1 - How can I test my packaging and its installation? 2 - Can deken packages be deleted/removed/name changed? 3 - Do I need to support all architectures on day 1? (currently I build Linux/Win) 4 - Where can I get the nice help templates used by Else/Cyclone &cet? Everything I've found online seems to be both massively out of date and expects that you already know how to use it. 5 - One or Two packages? Currently, I have two separate shared libs, one requires the Sensel library, one does not. I haven't checked the licensing yet, but I assume the Sensel library probably can't be distributed in a deken friendly way. So that's my list :) Any help would be greatly appreciated. The help template question is particularly vexing, as I find that help files for PD objects are *essential* to being able for me to figure things out, even when I grab someone else's code.

PD 0.51-4 bug fix candidates
by Dan Wilcox 20 Dec '20

20 Dec '20

Howdy all, As quickly discussed on GitHub, there are a couple bugs which may warrant a 0.51-4 release. In addition, here is a little list of things I think would be good fixes to have: windows: save-to-/tmp/foo.wav bug networking & libpd: getaddrinfo() rejects dual stack socket settings on BSD and Android (https://github.com/pure-data/pure-data/pull/1232 <https://github.com/pure-data/pure-data/pull/1232>) mac: update patch window size after configure (https://github.com/pure-data/pure-data/pull/1236 <https://github.com/pure-data/pure-data/pull/1236>) multi-instance & libpd: set pd_this for readsf~ and writesf~ threads (https://github.com/pure-data/pure-data/pull/1227 <https://github.com/pure-data/pure-data/pull/1227>) writesf~: fix infinite loop on I/O error (https://github.com/pure-data/pure-data/pull/1224 <https://github.com/pure-data/pure-data/pull/1224>) mac: add back-ported patch for Tk 8.6.10 which fixes disabled Help menu items (https://github.com/pure-data/pure-data/pull/1226 <https://github.com/pure-data/pure-data/pull/1226>), note: requires re-building and packaging Wish.app in mac/stuff -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>
