Ardour 7 can't find the LV2 plugins

[ScrawnyPetauro]

Hiya there!

So I compiled and everything works wonderfully in the standalone application, but I can't get Ardour 7 to see the LV2.

It is correctly installed in usr/local/lib/lv2, tried to copy the folder to /usr/lib/lv2/ but still no success.

Any ideas on how to solve this?

Thanks!

Did you get ardour to rescan for new plugins? (Ardour 7.2 can see the rakarrackplus plugins here)

[ScrawnyPetauro]

@trebmuh yeah, I did rescan for plugins, but nothing shows...

You can then look at Ardour's console log to see what it's grumbling about and copy/paste it here.

I uninstalled and recompiled just in case and the result doesn't change. Ardour log isn't much help either, except something about DrumGizmo (which works perfectly anyway).

On that note, DrumGizmo's lv2 in installed in ~/.lv2 can that make a difference?

what is the result of: env |grep PATH ?

[ScrawnyPetauro]

$ env |grep PATH
MANPATH=/usr/share/lmod/lmod/share/man:
MODULEPATH_ROOT=/usr/share/modulefiles
PATH=/home/***myusername***/gems/bin:/home/***myusername***/gems/bin:/home/***myusername***/.local/bin:/home/***myusername***/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/***myusername***/.dotnet/tools
MODULEPATH=/etc/modulefiles:/usr/share/modulefiles:/usr/share/modulefiles/Linux:/usr/share/modulefiles/Core:/usr/share/lmod/lmod/modulefiles/Core

[trebmuh]

Then it looks Ardour doesn't know where to search for those plugins. Hence, moving them to ~/.lv2/ can be a good idea. Alternatively, you can tell Ardour to look into /usr/local/lib/lv2/.

[ScrawnyPetauro]

moved to ~/.lv2/ and working fine now. Thanks!
