hi everyone!

I'm trying to run the patch "Ambisonic_2d_example.pd" from the iem_ambi external. While trying to get it to run, I made some changes to the declare statement. You can find the code below..

I installed the externals needed for this patch through deken and I also set the "-lib iemlib" startup flag in PD.

Unfortunately I get the following errors. As you can see PD fails to create some objects (e.g. fadtodb, rbpq, mull~, dsp). These objects seem to all come from the iemlib which is loaded successfully. I have also checked the /externals/iemlib directory.. the four mentioned object-patches are there.

I am running PD on a VM running Debian 11.7 on a M1 MacBook Pro.

I have been trying to solve this for a couple of hours now.. Does anyone know why it's not working?

Hi,

I am trying to get ofelia to run on a couple of rpi. Right now I am trying a rpi 3B+ running https://blokas.io/patchbox-os/

I run ofeila with the ofelia-fast-prototyping abs on my mac successfully.

Following install instructions here https://github.com/cuinjune/Ofelia
after running
sudo ./install_dependencies.sh
it ends like this:

gstreamer1.0-omx is already the newest version (1.0.0.1-0+rpi12+jessiepmg).
The following package was automatically installed and is no longer required:

Thankful for help!

I'm running Pd-0.52-2 on MacOS Monterey (12.6) and having trouble with externals that I created. When developing/debugging, everything is fine. I have 4 externals with extensions .pd_darwin, each dependent upon a DLL named libo2pd.dylib. With everything in ~/Documents/Pd/externals/, I can start my locally compiled pd-0.52-2.app, and everything works. But if I run a downloaded /Applications/Pd-052-2.app and try to create one of these external objects, I get the message:

/Users/rbd/Documents/Pd/externals/o2ensemble.pd_darwin: dlopen(/Users/rbd/Documents/Pd/externals/o2ensemble.pd_darwin, 0x000A): Library not loaded: 'libo2pd.dylib'
  Referenced from: '/Users/rbd/Documents/Pd/externals/o2ensemble.pd_darwin'
  Reason: tried: 'libo2pd.dylib' (relative path not allowed in hardened program), '/usr/lib/libo2pd.dylib' (no such file)
 o2ensemble o2global
... couldn't create

I get the same results running from the command line, and running from the directory with the .dylib and externals does not make any difference. Note that /usr/lib is protected even using sudo, so even if I could install libo2pd.dylib there, I don't think it's an acceptable solution.

I suspect this problem stems from Apple security policies, but I don't know how Pd searches for .dylibs and there's a lot of ambiguity in documentation and discussions since "libraries" and "paths" are used in multiple ways. I also tried setting LD_LIBRARY_PATH and running from the command line, but that didn't work.

Does anyone know to set up Pd for an external that depends on a DLL?

Hello all,

I have recently stumbled into some problems compiling PD externals. I figured I would post here, it's a two part question

Compiling on/for Windows:
The first, and likely easier question, is I am trying to compile this external for the ES-5 encoder provided by Expert Sleepers for their DC coupled Eurorack interface:
https://github.com/expertsleepersltd/externals/tree/master/pd/es5encoder~

However, when I attempted to run the makefile I am encountering numerous errors that lead me to believe my environment isn't setup for compiling PD externals. Is there somewhere that outlines how to compile an external like this where there is limited/no documentation in the README? I don't know how generic of a process it is and if it's fairly standardized.

Second question:
I have a library that I would like to use with PDParty (iemmatrix) and I need to compile this into a static library to be able to use it on iOS. Is compiling to a static library drastically different than to a dynamic one? Are there limitations design wise that particular libraries might be incompatible with?

Sorry if the wording here is confusing at all. I haven't dealt much with compiling libraries for different platforms so I am a bit lost on some of the basics.

Any help, as always, is greatly appreciated

Hey, I'm trying to get purr-data to work on my fresh Manjaro XFCE install, but it does not work. Any help is greatly appreciated!

... couldn't create

I wanted to build PD on Windows 10 to get ASIO support. I failed when I used the "Source" files from the PD website. I succeeded when I used source that I cloned from Github. I followed the same instructions from the wiki both when I failed and when I succeeded. (They are the same as in the manual, just a little more concise.)

I am sharing below my terminal output from the failed build attempts from the downloaded source code (the tar.gz file). Some of these messages suggest that there might be errors in the makefiles. I don't know anything about makefiles, so I can't really interpret the errors. But I did want to pass them along, in case a developer might find them useful. Here you go:

As a further test -- I hacked ./tcl/helpbrowser.tcl to print to stdout some progress messages while building the help browser directory list. (Doing this in Linux -- I haven't set up the Windows machine to build Pd from source.)

To my surprise, I found that the Externals Install Directory is part of $::sys_staticpath (in Linux).

Each entry in $::sys_staticpath is globbed for any subdirectories -- so this is how it's finding Gem, cyclone, zexy etc.

staticpath add search /home/dlm/pd-externals/Gem
staticpath add search /home/dlm/pd-externals/freeverb~
staticpath add search /home/dlm/pd-externals/zexy
... etc.

A little bit later, it checks $::sys_searchpath -- this comes from preferences. These entries are not globbed for subdirectories.

searchpath add search /home/dlm/pd-externals

(Above is the only entry coming from Preferences > Path.)

So one possible difference is that the "static path" includes my external location in Linux (that isn't speculation -- the stdout listing proves it), while it probably doesn't in Windows.

OK, then, let's grep staticpath... this leads to s_path.c, which says (in an ifdef for Linux):

sys_expandpath("~/pd-externals", pathbuf, MAXPDSTRING);
STUFF->st_staticpath = namelist_append(STUFF->st_staticpath, pathbuf, 0);

So user-home/pd-externals is a special, hardcoded location for Linux, which I happen to be using for my externals.

Looking a bit further down, hardcoded locations in Windows are AppData/Pd and something about common-program-files/Pd -- but the Pd GUI recommends Documents/Pd/externals as the installation directory. (And Mac will have a similar problem, because the hardcoded locations include ~/Library/Pd but again not Documents/Pd/externals.)

I'm satisfied that this explains the difference in behavior between the two environments. But it leaves a bit of an impression that this hasn't been completely thought through. If there are magic locations for help browser search, ideally this would be coordinated with recommended installation directories, but they aren't.

@flight453 i have made an abstraction for this, feel free to use as you like. velocity-senitivity.pd just download it and call it in your patch.

when you call a patch (or any normal file) in pd through directory traversing in objects, there are some rules (idk if i know all, because i have just stumbled upon them randomly):
a: to call a patch in the same directory (folder) as your main patch, just type out the name, excluding the ".pd" at the end, so velocity-senitivity.pd becomes velocity-senitivity.
b: to call a patch inside a directory which is inside the same directory as your main patch, just type the directory name for the directory inside the shared directory, then a "/" and then the filename, again, excluding ".pd", so velocity-senitivity.pd inside the directory "abstractions" which shares the directory with your main patch, becomes abstractions/velocity-senitivity. you can go as many directories in as you like, so abstractions/midi&more/velocity-senitivity
c: if it is outside your directory type one "." for as many directories you have to go outside and then "./" (yes, that is a "." followed by a "/") and then your patch name, again, excluding ".pd".
d: you can type what rule "c" says and not entering the patch name, and then type what rule "b" says. here's an example of this in action .../abstractions/midi&more/velocity-senitivity, so the ".../" means that you shold go back 2 directories, and "abstractions/midi&more/" means that you should go inside the folder "abstractions", and then "midi&more", and "velocity-senitivity" is the the patch that you want to use.
e: just typing out the full directory, again excluding the ".pd"

you'r welcome

I know Pd wants me to use viual studio (i'm on windows, i will switch to linux when i havue time for it) to compile externals. It also wants me to use a shell, but idk how to do that. i opened a powershell window in the external that i wanted to compile, but when i entered in "nmake" and "pd_nt" there nothing happended. The external was downloaded on SourceForge and i unzipped it twice to get out the contents.

Can somebody explain how to compile an external as much as practically possible?

Also, where should i put my externals? is it in "lib", "extra", something else or should i make a new folder for externals? I currently made a new folder to externals called "externals" because i saw a youtuber having a folder named that for his externals.
