This is "just" a compiler warning which could be easily switched of by add the compile flag -Wno-unused-result . It's not a error. In fact, here we didn't care about the return value as it didn't matter in this case. You should find the build in the ./bin folder anyway.

[brummer10]

I've pushed a fix for it to github now, implement the -Wno-unused-result flag.

[crazytelli]

Thanks for the quick response.

I can see the files in ~/.lv2/ as shown below:

But when I launch Carla or Ardour I'm not able to bring the UI.

[brummer10]

So you've run make install could you check the content of the manifest.ttl file there, it should be

@prefix lv2:  <http://lv2plug.in/ns/lv2core#>.
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#>.
@prefix state: <http://lv2plug.in/ns/ext/state#> .

<http://github.com/mikeoliphant/neural-amp-modeler-lv2>
    a lv2:Plugin;
    lv2:binary <neural_amp_modeler.so>;
    rdfs:seeAlso <neural_amp_modeler.ttl>;
    rdfs:seeAlso <Neural_Amp_Modeler_ui.ttl> .

you may also check the log window from carla,

mm, then I've no idea what goes wrong. Are you able to load any other X11 based plugin GUI's like the guitarix lv2 plugs, or this one https://github.com/brummer10/ImpulseLoader.lv2 or this one https://github.com/brummer10/Ratatouille.lv2

do you use wayland?

[j1-dev]

I'm having the same problem using arch and wayland. I also tried installing xorg-xwayland which supposedly let's you run X11 applications in wayland but it doesn't seem to work
