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

@skautkurt Try running with the "-verbose" flag and tell me what it prints to the console before the chaos: can't load library message.

edit: solved

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
---

---
>       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...

Did you mean [declare -lib chaos]?

@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.

I've never heard of it. What is it supposed to do?

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.

@skautkurt That's the "import" object help patch.

I actually like its interface a lot better than [declare] (I don't like flags in object arguments). But [declare] is really the standard object for loading libraries so I'd recommend using it instead of import.

I added an issue for Purr Data about this in case anyone wants to attempt fixing a simple issue:
