libpd / pd-for-ios Goto Github PK

I'm currently upgrading my app to 64-bit so I can release it to the app store.. It relies extensively on the libpd libraries.

My code works perfectly in 32 bit.. However, on arm64 standard architectures (as specified by Apple's new standards) - libpd compiles, but crashes immediately at runtime.. The offending code is here, in d_arithmetic.c :

static void scalartimes_dsp(t_scalartimes _x, t_signal *_sp)
{
if (sp[0]->s_n&7)
dsp_add(scalartimes_perform, 4, sp[0]->s_vec, &x->x_g,
sp[1]->s_vec, sp[0]->s_n);
else
dsp_add(scalartimes_perf8, 4, sp[0]->s_vec, &x->x_g,
sp[1]->s_vec, sp[0]->s_n);
}

dsp_add is causing an EXC_BAD_ACCESS error. Has anyone managed to compile libpd in 64 bit?

I've been through every single instance of 'malloc' in the project and added 'sizeof' to them, but it still crashes here.

I tried replacing the libpd source with the files from Miller Puckette's 64-bit update - Pd version 0.46-5, 64 bits, compiled for Macintosh OSX 10.8 or later, from Miller's website - but now I'm getting compile errors in z_libpd.c here:

sched_tick(sys_time + sys_time_per_dsp_tick);

and

int libpd_process_short(int ticks, short *inBuffer, short outBuffer) {
PROCESS( short_to_sample, * sample_to_short)
}

with PROCESS returning the error: 'too many arguments to function call, expected 0 have 1'

I hope someone can help, I'm ready to release my app, and Apple's new standards have caused me to pull my hair out.

Here's dsp_add():

void dsp_add(t_perfroutine f, int n, ...)
{
int newsize = dsp_chainsize + n+1, i;
va_list ap;

dsp_chain = t_resizebytes(dsp_chain, dsp_chainsize * sizeof (t_int),
newsize * sizeof (t_int));
dsp_chain[dsp_chainsize-1] = (t_int)f;
va_start(ap, n);
for (i = 0; i < n; i++)
dsp_chain[dsp_chainsize + i] = va_arg(ap, t_int);
va_end(ap);
dsp_chain[newsize-1] = (t_int)dsp_done;
dsp_chainsize = newsize;
}

Thanks,

I am having issues in building/ linking the example project. Am I missing something? Any advice greatly appreciated..

MacOS Big Sur Version 11 beta
Xcode Version 11.6
as a deployment target, iOS 8

Compiling PdLinkSample in XCode 10.1 does not work anymore. Using LinkKit 3.0.4 I get the errors

"Implicit declaration of function 'ABLLinkCaptureAppTimeline' is invalid in C99"

and

".....pd-for-ios/pd-for-ios/PdLinkSample/PdLinkSample/ViewController.m:41:5: Use of undeclared identifier 'ABLLinkTimelineRef'; did you mean 'ABLLinkTimeAtBeat'?"

for the line

ABLLinkTimelineRef timeline = ABLLinkCaptureAppTimeline(linkRef);

in ViewController.m

When building from XCode it the target "libpd-ios" it does not generate the static library.
It works for the "libpd-osx" target.

I updated submodules successfully.

XCode 5.0 / OS X 10.8.5

I thought I would post these here instead of letting them pass unmentioned... I am running Circle Of Fifths and both the master branch and opensl branch give the follow errors at startup:

07-09 00:55:59.620: E/AudioTrack-Java(19859): [ android.media.AudioTrack ] getMinBufferSize(): Invalid channel configuration.
07-09 00:55:59.620: E/AudioTrack-Java(19859): [ android.media.AudioTrack ] getMinBufferSize(): Invalid channel configuration.

I am not familiar with this part of libpd, so I'm not sure what is failing, just thought you should know if you don't already..

I have been following along with the book "Making Musical Apps," and I get an error when building: "Apple Mach-O Linker Error OBJ_C$_PdAudioController." I have a feeling that it has to do with the "User Header Search Path," I'm pretty confident that I have it correct.

Any help would be greatly appreciated! I really want to get to know Pd...

Hello, I think that I've pd ios configured correctly , but I can't get sound on my tests , on simulator.
right now I don't have an ios device to test in with a real device. So I'm stuck on simulator.

This is the console output maybe it could help

im trying to make multiple instance of pdbase but couldnt find a way. can anyone explain how to make multiple instances of one pdfile?

Hi,
I haven't been able to build and run the PdLinkSample project in XCode. I keep getting "undefined symbols" compilation errors (see below). I have carefully checked my library and header search paths. I have tried various C++ compiler options in XCode. No luck so far. Has anyone had the same issues? Sounds like I am missing a particular setting somewhere, but which one?

if using external in objective C,
extern prototype_tilde_setup();
will not work
will need extern "C" { prototype_tilde_setup(); } for externals ...

Maybe good to put this in the help page because I got stuck on it for a while.

A different error in Circle Of Fifths, this one only in the opensl branch. When press on one of the keys in the circle, I get the error message:

Everything else seems to be running fine.

I've had this crash in my app on the audio thread that I can't seem to figure out since it happens inconsistently. Anyone else run into this?

Hi there,

My project is a synth with a built-in sequencer that uses libpd's implementation of Ableton Link, and occasionally I will have sync problems where a log message similar to this will appear:

AUD003534z2: Scheduling trigger update 1955079072

In this particular case I am receiving MIDI from an IAA source; when I press the global IAA play button, the sequencer fails to play (it doesn't receive an increase in beat time or steps), and the above message appears.

I'm just wondering if this is generated by Link or libpd? If not libpd related, feel free to close this issue. I've reached out to the Link developers as well.

This is to track this. Not sure yet if I'll get a chance to do it myself or not.

steps to reproduce:

• Run project on iphone 4s (probably others as well)
• click on the 'Resynthesis' button, selecting the resynthesis.pd patch and closing the other patch.
• there is an exc_bad_access that leads back to the patch being closed in it's dealloc.

I think this has only been happening since the new ringbuffer was introduced, but I'm not yet sure.

Is there any chance to include the libpd/pd-for-ios for the project xCode with SwiftUI ? Is it possible to update the documentation on this issue?

if i have multiple [abl_link~] objects in my running Pd instances, they all share the same connection state.
That is: if i [connect 1( one instance, the other instances will be connected to the global (networked) session as well.

also, multiple [abl_link~] objects in a single Pd instance are connected with each other, even if they are not connected with a global session.

After changing the Architectures build setting to ARCHS_STANDARD_32_BIT I could compile the PdTest02 demo for iOS6 but it does not produce any sound. It works fine on iOS5 and in the simulator.

iPhone 4 iOS5 = Yes
iPhone Simulator iOS6 = Yes
iPhone 5 iOS6 = No
iPad 3 iOS6 = No

Any ideas why this is not working?

So I downloaded pd-for-ios a few months ago, but accidently deleted the pdtest01 sample project.
So I re-downloaded it today, and I noticed that the libpd folder was empty.
This isn't a problem for me since I already have the files, but for a first time downloader...

I have seen that people worked on that issue, but I still get an error with Xcode 9

s_file.c creates an error with system(cmdbuf);

static void sys_putpreference(const char *key, const char *value)
{
char cmdbuf[MAXPDSTRING];
snprintf(cmdbuf, MAXPDSTRING,
"defaults write org.puredata.pd %s "%s" 2> /dev/null\n", key, value);
system(cmdbuf);
}

In Xcode, all the of the other receive functions autocomplete for me, except for receiveFloat, which doesn't seem to work or register at all, even though it exists in PdBase.h with the other functions that do work (recieveMessages, receiveBangFromSource, etc.).

Is there a way to get this function to work?

Thanks!

thanks for sharing [abl_link~] via deken.

however the deken-file lacks the Makefile to build the external.

please provide it in future uploads.

please use variables for the paths to 3rd-party modules, e.g.

     LINK_INCLUDE=./link/include
     ASIO_INCLUDE=./link/modules/asio-standalone/asio/include

     cflags = -std=c++11 -I$(LINK_INCLUDE) -I$(ASIO_INCLUDE) -Wno-multichar

Kindly can you provide instructions to make a build from Unity for iPhone and iPad
