Hey hey,
I have noticed issues with liblilv for a while now. Upto now, it mostly hasn't
harmed me, but I suspect some other challenges I've had to result from these
errors. This is what I get:
lilv_world_load_bundle(): error: Error reading
file:///usr/lib/lv2/ProM.lv2/manifest.ttl
substitute the LV2 plugin of choice. I notice that with both Ecasound/Nama and
mod-host. I think lv2apply also printed that message, when I used it the other
day.
Could someone throw some light on this? Any helkp is appreciated.
Best wishes,
Jeanette

I haven't noticed any problems with lilv using jalv or Ardour. I'm using
a freshly compiled lilv-git AUR package.
Does 'lv2ls' also give the same error message? If this affected all LV2
plugins, lv2ls should probably fill up your terminal with these.
Could it be simply a permission error? Maybe you accidentally set
/usr/lib/l2 to 0700 permissions or similar?
You could try running this test script for the Python bindings to check
whether the error really is in lilv and not the programs using it:
https://github.com/drobilla/lilv/blob/master/bindings/python/lv2_list.py

No, lv2ls is OK.

I have checked /usr/lib/lv2 itself and its subdirectories and they are
OK:
0755
This too
worked perfectly.
...
My system is not running a GUI server, the libraries are there and all
plugin dependencies should be there, since they are installed through
the arch pacman manager. Could you think of another approach?
Best wishes,
Jeanette

On gentoo, I use a lilv-9999 ebuild which install its git version. Now,
I don't remember why I shifted to that version.

If you have a problem and you are not doing anything to fix it, you are
at the heart of the problem.

Just to be clear: is it always this exact
message (i.e. relating to
ProM),regardless of which LV2 plugin you're using? Or do you get an
error relating to the manifest.ttl file of the plugin, which you are
currently trying to use?
Do you just get an error message and things seem to work normally or
does loading the plugin actually fail?

It is not only ProM, I'm
not sure if I get the message for ALL installed
plugins, but a lot.

Hm, interestingly, it isn't just the plugin I use. It
seems to be part
of a system-wide search/p0reparation/setup procedure.

Plugins will load and I think(!) normally
work just fine. I am not sure
whether my current CALF Vinyl issue is related to this.

Best wishes and thanks,

Ok, so somthing seems to be generally wrong with loading manifest.ttl
files. Just a thought: maybe try to update the serd and sord packages?
As a side note: I maintain AUR VCS packages for all of David Robillard's
LV2 related software packages so I always have them compiled from
reasonably recent state or theier respective Git repos. Here's a script
I use to recompile them from time to time:
#!/bin/bash
PACKAGES="serd-git sord-git lv2-git sratom-git suil-git lilv-git jalv-git"
for d in $PACKAGES; do
if [[ ! -d "$d" ]]; then
git clone https://aur.archlinux.org/${d}.git
pushd "$d"
else
pushd "$d"
git status
git pull
fi
makepkg -fi
popd
done

Yes, when you use lilv to load a plugin, it triggers a discovery process
for all LV2 plugins, the loading of the so-called LV2 "World", as can be
seen in the Python script I linked earlier.

Thanks for the suggestion and the script, this is neat. I will
investigate this. There's always the question of dependencies for the
apps that I use. But it sounds very much worth it...

for d in $PACKAGES; do

git clone https://aur.archlinux.org/${d}.git
pushd "$d"
else
pushd "$d"
git status
git pull
fi
makepkg -fi
popd
done
...
Best wishes,
Jeanette
PS: I did spot the lilv world call and assumed that it might be
triggered everytime, but uninformed assumptions... :)
