[chuck-users] Re: Chugl error for chuck 1.5.5.2

16 Sep 2025

      My bad.. I forgot that Chugl does not
install like the other chugins and
had a left over version in ~/.chuck/lib
(which works with the older chuck.)

I copied the new chugin to /usr/local/lib and 

[chuck:2:SYSTEM]:  |  | [chugin] ChuGL.chug [OK] (API version: 10.2)
[chuck:2:SYSTEM]:  |  |  | version: 0.2.6 (alpha)
[chuck:2:SYSTEM]:  |  |  | author: Andrew Zhu Aday & Ge Wang

so it looks good,  but  the circles.ck from examples/basic  fails.
maybe I am  missing some dependencies?

The error suggests that your ChuGL chugin is an older version 
(specifically, it was built with an older chugin.h header) --
compared with your chuck host, which is on the latest release
(1.5.5.2). Since you appear to be on Linux, one remedy is to re-build
and re-install the ChuGL chugin on your system. FYI here is the
latest ChuGL release tag (which is associated with chuck-1.5.5.2):
https://github.com/ccrma/chugl/releases/tag/v0.2.6
I hope this helps!
All the best,
Ge!

I'd prefer not do create a discord account.
I'm still  (foolishly) trying to minimize my internet footprint.
Anyhow the most recent chugl chugin seems
to have an problem.
Probably an easy fix.
