Unrecognised sc3-plugins Ugens

Questions
1

I am experiencing something off with a newly compiled SC on linux. After updating my system I compiled SC from source. Went well. I downloaded the sc3-plugins and unxip into the local extension dir. But when I evaluate a synthdef with with some ugens from it (e.g. DWGPlucked) SC complains that the ugen is not installed. I can get the help files for the ugen to show in scide, the source file DWGPlucked.sc exists in the sc3-plugin extension folder. So I am mystified.
Any suggestions how to find out and solve the problem will be much appreciated.

Hey, just to be sure, can you verify that you actually put the sc3 plugins into the extensions folder and not into the quarks folder?

You can check the contents of the extensions folder e.g via

(
"user extensions".postln;
PathName(Platform.userExtensionDir).entries.join("\n").postln;
"system extensions".postln;
PathName(Platform.systemExtensionDir).entries.join("\n").postln;
)

where something like PathName(/Users/scheiba/Library/Application Support/SuperCollider/Extensions/SC3plugins/) should appear.

Yes, I did check the extension dir. Here is the output:
PathName(/home/oded/.local/share/SuperCollider/Extensions/FluidCorpusManipulation/)
PathName(/home/oded/.local/share/SuperCollider/Extensions/SC3plugins/)
PathName(/home/oded/.local/share/SuperCollider/Extensions/SCMIRExtensions/)
PathName(/home/oded/.local/share/SuperCollider/Extensions/UKalman/)

and SC does find Ugens from FluCoMa extension

Which version of SuperCollider are you using?
Can you check via ls -alh whether there are some different file permissions between the flucoma plugins and the sc3-plugins folder/files?

I compiled the latest version from github - 3.14.0 . Is it possible not compatible with the plugins?
The permissions are identical for all the extensions (rwx for user; r-x for everyone else)

thanks

I just did a fresh build from develop and installed the sc3-plugins w/o problems.

Can you verify that the .so files are also present in /home/oded/.local/share/SuperCollider/Extensions/SC3plugins/?
The sc3 download contains the folder with class library files (which seems to work on your machine) and the actual plugins as binaries (.so) - these need also be located in your SC3plugins folder.

Is it possible that you are on an arm64 machine?

ah, so that is the problem. The .so files aren’t there. Do I copy all of them into Extensions/SC3plugins/ ?

Yes - IIRC every folder within Extensions is scanned recursively for .so files - so I’d put all .so files into e.g. /home/oded/.local/share/SuperCollider/Extensions/SC3plugins/plugins/
