Guitarix: Error-Messages due to missing gx_colwah.lv2 files about meta-musicians HOT 7 CLOSED

Yes similar here: In qtractor this plugin is grayed. Unfortunately I am no expert at proper contents of turtle files @brummer10: Have attached the ttl.
gx_colwah.ttl.txt
Is there something missing this plugin requires (e.g. MOD as mentioned in turtle title)?

from meta-musicians.

I'm afraid, it's a upstream bug. It's fixed within our latest release.
Here is a patch to fix 0.39.0 in case you wouldn't update now to 0.40.0.
https://salsa.debian.org/multimedia-team/guitarix/-/blob/master/debian/patches/1000-wah_colwah_fix.patch

from meta-musicians.

Thanks a lot. Will first try the patch and then upgrade to 0.40.0. Did start the upgrade already but there were issues - so I might ask again then.

@brummer10:

The referenced patch does not apply cleanly on 0.39.0 so I decided to upgrade to 0.40.0 now - it is on my TODO since 0.40.0 was announced - but...

On all sources (tarball / your repo at https://github.com/brummer10/guitarix) build fails with:

I think upd() is called with None because when I modify as
test.patch.txt

Build continues a tiny bit but fails later with:

Any suggestions?

The referenced patch does not apply cleanly on 0.39.0

That may be related to the diff in the Fix-LV2-types.patch (const struct _LV2UI_Descriptor) you use, maybe use this instead will lead to a clean apply:
https://salsa.debian.org/multimedia-team/guitarix/-/blob/master/debian/patches/0002-Fix-LV2-types.patch

Any suggestions?

I've seen similar errors which was related to anaconda been installed.
Other than that, here is a tread about building guitarix 0.40.0 on a Pi 3B+,
brummer10/guitarix#8
It turns out that some small patches been needed to make it build and run successfully on a ARM device.

from meta-musicians.

I re-read discussion on linuxmusicians [1] and the first result is: adding --no-faust fixes compile.

Hi,

thanks very much for the fast responses and the fix!
The recipe for 0.40.0 compiles and starts now without any errors.
