I just found this:

but maybe that was only relevant in vanilla? Sorry for the confusion, I'm really new to all this. It made sense to me from my experience with "conventional" programming.

@jancsika No, I meant

[include chaos]

I found that in some documentation of that external, and used it, and it seemed to work before. But right now it always throws an error, so I left it out, and the external still works.

Okay, I managed to get the library compiled and working! It required some makefile hackery. This applies to MacOS 10.14.4, and using gcc-9 installed via brew (clang threw errors left and right...)
Here is the output of diff comparing my edited version of the makefile to a freshly unzipped one:

➜ chaos-0.2 diff Makefile ~/Downloads/chaos-0.2/Makefile
99d98
<     CC=/usr/local/bin/gcc-9
104,105c103,104
<     PD_PATH = /Applications/Pd-l2ork.app/Contents/Resources/app.nw
<     OPT_CFLAGS = -ftree-vectorize -ftree-vectorizer-verbose=2 #-fast
---
>     PD_PATH = /Applications/Pd-extended.app/Contents/Resources
>     OPT_CFLAGS = -ftree-vectorize -ftree-vectorizer-verbose=2 -fast

<       FAT_FLAGS = -arch x86_64
---
>       FAT_FLAGS = -arch ppc -arch i386 -arch x86_64 -mmacosx-version-min=10.4

Also, this is how my startup panel now looks like

Strangly I don't need to [include chaos], that simply does not work...

edit: solved

Hi People,

I am trying to get the chaos-0.2 external to run in Purr Data. Somehow I actually got it running, but suddenly it's not working anymore, and I just get chaos: can't load library. I read somewhere that one would need to compile the external first, but trying that I only get errors as well: ➜ chaos make cc -I"/Applications/Pd-extended.app/Contents/Resources/include/pd" -DPD -DVERSION='"0.2"' -arch ppc -arch i386 -arch x86_64 -mmacosx-version-min=10.4 -fPIC -I/sw/include -Wall -W -g -ftree-vectorize -ftree-vectorizer-verbose=2 -fast -o "attract1.o" -c "attract1.c" clang: error: unknown argument: '-ftree-vectorizer-verbose=2' make: *** [attract1.o] Error 1

Is there a way to get this running? If yes, how so?
Thanks in advance.
Timo

Answering myself:

resetting the prefs of Purr Data seems to do the trick: on Mac its
rm ~/Library/Preferences/org.puredata.pd-l2ork.plist
and then restarting pd. The startup settings now seem to be populated.

Hi,

I might be a little late to this post, but I have the same problem with pd-l2ork (version 2.5.1 edit: on OS X 10,12.6).
My Search Paths as well as my libraries and startupflags are completely blank, right after installation. I can't find the .plist files @maaark was talking about, can you maybe tell me where you found them?
Are there other fixes I could try?

(this is how it looks right now, shortly after the installation)

Maybe you know a fix, would love to hear it,
best
