Dear fellow ChucKists, Here is a bundle of recent updates! (For regular update, please join the ChucK Community Discord server): https://discord.gg/Np5Z7ReesD ChucK 1.5.2.5 is released: https://chuck.stanford.edu/release/ | What's new? https://chuck.stanford.edu/release/VERSIONS all new WebChucK IDE (v2)! https://chuck.stanford.edu/ide/ Chunity updated on the Unity Asset Store; many stability improvements and updated to the latest ChucK: https://assetstore.unity.com/packages/tools/audio/chunity-chuck-for-unity-11... ChuGL (ChucK graphics library, in alpha) has been part of the standard distribution since 1.5.2.1; give it try! https://chuck.stanford.edu/chugl/ === Want to learn more about recent ChucK and related developments? Here are some publications, to be presented next week at NIME 2024 (New Interfaces for Musical Expression) in Utrecht, Netherlands: Andrew Zhu Aday and Ge Wang “ChuGL: Unified Audiovisual Programming in ChucK.” https://mcd.stanford.edu/publish/files/2024-nime-chugl.pdf Marise van Zyl and Ge Wang “What’s Up ChucK?

Maybe this list is dead ? 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.

This list lives! (and fwiw I applaud the effort to minimizing one's internet footprint!) 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!

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]: | | | version: 0.2.6 (alpha)

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