I’m using Ardour6.9 on W10 on my old laptop, now I’m moving to a different machine, installed ardour on it (same installation file 6.9.0)
created the folder:
C:\Program Files\Common Files\VST3
and copied there my file as I did on the old laptop, here I stop because there’s no way to load it, here below the screenshots of VST options on old and new machine[Processing:
I got the same error message for one VST3 plugin I use from White Elephant Audio called MONSTR (Stereo Imager) on Linux in Ardour 6.9.0 (flatpak). I still use Ardour 6.7.0. and this is not an issue. This screenshot below shows that I saved plugin in two locations and gets the same error message. I use Bertom Denoiser (a gate noise reduction plugin) and it works fine even though it is in the same folder as my VST3 plugins.
Keep in mind the plugin that gives an error message is in 64-bit so it should work in the latest version of Ardour.
So the plugin was dynamically linked and depends on external system-wide libraries.
here: libcurl-gnutls.so which is not present on your system – perhaps because libcurl-nss or libcurl-openssl package is installed instead.
Plugins should be statically linked for that purpose. Say you have yet another plugin that relies on libcurl-openssl.so then the two plugins will conflict.
There is nothing we can do about this, best contact the plugin vendor and ask them to compile the plugin in a way that does not rely on external libraries.
@x42 I have a separate question relate to this issue.
After reading your quote in this forum below from a few months ago Called “Ardour as a Snap or flatpak”, you mentioned this:
(Ardour as Snap or Flatpak)
“The problem with either is that plugins also need to be inside the flatpak or snap. So 3rd party plugins cannot be used [1].”
I am using Ardour 6.9.0 which is available as a flatpak in my software manager for download (I am using Linux Mint). It seems to me that 3rd party plugins work in it as VST3 plugins like my Denoiser plugin as shown above. I just want to make sure if your quote applies to the flatpak of Ardour I am using.
If the plugin is self-contained (no external dependencies) and installed in $HOME/.vst3 or $HOME/.lv2 it should indeed work.
As for other plugins esp system-wide installed ones, things are more complicated. There is ongoing work to support those. Particularly a shared runtime env is required:
