Carla failed to load file

Post by LinMusGuy »

After experimenting with diverse programs on my Linux Mint 19.3 computer suddenly LV2 plugins no longer work in Carla while VST-plugins still do. See:

What could be the problem?

Hi @LinMusGuy,
There is a similar issue on the Carla github: https://github.com/falkTX/Carla/issues/1063

Thank you but I think this is somewhat different. The LV2 plugins are seen and recognized by Carla but not loaded.

What's strange in you error is the fact it's about VST (!!!).

Could be there are LV2s in the wrong path?

When I open the LV2 plugins via the Add-button (see below) there's no error message!

And could this message have something to do with it?

I think the best way is from "Add Plugin" menu, if you select the plugin in the file browser i think Carla is not opening the LV2 in a correct way. :D

I have just now downloaded a new version of Carla, but exactly the same problem here! Strange how my old way of doing things has suddenly
become impossible! Well - I guess I will have to use the Add-button from now on, at least for the LV2 plugins. Strange!

I don't think so, Win plugins haven't the ".so" extension.

I have now installed the latest version of Carla (2.3.0), but the final part of the installation failed:

I didn't understand the "adjust as needed" clause. Further starting Carla form the terminal gives this message:

Code: Select all

However Carla does start. But I still can't find all of my LV2 plugins by means of the Add button.

It looks like the extension ".lv2" is no longer recognized on the Desktop of my computer, it automatically turns into ".so". And this could be a problem as I keep my LV2 plugins in a map on my Desktop...

I can't find "winegcc"! Where can I download that program?
