Hi @prokoudine,

Thank you for reporting back.

Can you provide more contextual information please?

CPU model: Ardour version: Logs for failing LV2 too:

Does VST2 worked?

So far looking at the logs points that your glib version required is missing. Can you check also what is your GLIBC version on Ubuntu 23.04?

your glibc library is older than the one required by JC303 plugin(GLIBC_2.38).

Can you please run the following command so we can know wich version you have right now on your system: $ ldd --version

I will try to get a minimun requirements to make sure the compiled version works on most used linux distros out there.

So the solution will be to compile another release with an older glibc to make it compatible with distributions that uses older versions of glibc.

$ ldd --version ldd (Ubuntu GLIBC 2.37-0ubuntu2) 2.37

Thank you,

I will release a new package with the plugins using a older GLIB, i will keep you posted here when its done, so you can download the new and compatible with your distro.

I've updated the latest release pack with a versions compatible with your distro and others most used around. also put a note on glibc minimun version required.

Can you please delete the old .zip file and download it again? same link: jc303-linux64-plugins.zip

Please let me know!

Thanks, that works!
