Hey @portaloffreedom, I'm using your PKGBUILD to test. I can use the Microphone OK on my laptop (can't tell on my desktop, because it doesn't have a mic).

I am hitting a wall trying to use skills, though. I am getting the following error:

>>> systemctl status --user mycroft-skills

Have you been seeing this too? Not sure if this is something to ask the Mycroft devs about.

@portaloffreedom I tried it with systemctl --user mycroft.target and I also tried it by running the scripts manually. I'm also using PulseAudio

@schrieveslaach Update: I got the same error as well. But I cannot reproduce it with certainty. Have you started it manually or with systemctl --user mycroft.target?

@schrieveslaach mmmmm, not really sure. I'm using pulseaudio and haven't tryed with Jack. Are you using jack in your system? It seems to me that is trying to connect to alsa and alsa to jack...

@portaloffreedom, I tried your version, however, the microphone is not working:

Do you have any idea what the cause of the error is?

@portaloffreedom, that looks nice. Tomorrow I have time to look into your code changes. Getting rid of virtualenv would be very nice.

Additionally, I found some other issues in the Mycroft core, I need to resolve.

So, I kind of overdid it. I made an entirely new package inspired from the opensuse package. You can find it here (it works!) https://git.covolunablu.org/portaloffreedom/mycroft-core-PKGBUILD

Other then working, the main differences are that my package doesn't use virtualenv hacks and uses python3.

If the mantainers of this package want to copy it into this, they are more than welcome. I would like to have this PKGBUILD for everyone but I don't want to create a duplicate on aur. If you don't want to use what I create for this package, then just tell me I'll come up with an idea for a new name in aur.

By the way, there maybe two possible bugs in mycroft-core.install.

1. In post_remove(), I suspect the group to be removed should be mycroft-core (forgotten dash)
2. In post_install() or somewhere, it may be necessary to set the default permission (maybe through mask or umask?) of the directory /usr/share/mycroft-core(or some of its subdirectories) to 0775, otherwise the user may not be able to alter that directory (so won't be able to install skills).

One last thing: is /usr/share/xxx a good place to install things which can change itself? Maybe /opt/ is a better place?

(I haven't made the software to run correctly, so I haven't had any experiences... Forgive me if any inference is wrong.)

@portaloffreedom Yes, I also solved that by installing libfann. However, I'm still getting trouble using the software, and was hoping to post the solution together... Though I can't get the software work. Do you have any clue?

in the post_install script I get a compilation error

    creating build/temp.linux-x86_64-2.7/fann2

    /usr/bin/ld: cannot find -ldoublefann
    collect2: error: ld returned 1 exit status
    error: command 'g++' failed with exit status 1

it seems there is a missing dependency in the package: libfann (installing the libfann package gets rid of the error)
