backtrace: symbol not found

A COPY PASTE TO HIDE THE SUBMITTER'S EMAIL ADDRESS

Hi John,

I just installed the alpine numen package in an lxd container and came across the error below. Is that a known issue?

Max

Hi Max,

Sorry, I've never seen that before and I'm not sure what it's about. I use Alpine and the package on my machine all good, but have never done anything with containers.

No clue if it's related, but I remember building vosk for musl required avoiding the backtrace function: https://gitlab.alpinelinux.org/alpine/aports/-/blob/master/community/vo sk-api/APKBUILD#L59

Hope you figure it out, John

Thanks John. The error suggests indeed that backtrace is somehow required in an lxd container but I'm not going to pursue in that direction. I realised in the meantime that a setup based on an lxd container is not going to cut it in my use case. The idea i had was to use it as a server to execute commands remotely on an android smartphone. Since Vosk is an offline solution this would simply obliterate its main advantage. Now i'm looking into running it locally with termux and chroot. The installation is smooth but dotool gets permission denied on /dev/uinput during numen processing. I've granted all permissions that was possible to grant to termux, but i think i need to do more digging

Cool! I'd really like to have an input solution for android too.

Later on you might want to see: https://lists.sr.ht/~geb/numen/%3C55fe1488feeb1cee2627d61b9b7e16a74ef5f ca0.camel%40dalibo.com%3E#%3CCWQ1POME5GNO.1LLY1OSMAO2X6@johngebbie.com% 3E about making numen less trigger-happy.

If you're going for more of a voice assistant, I know of dicio for android that also uses vosk: https://github.com/Stypox/dicio-android

But I'm interested in if you get termux input working!

~masq a day ago

It works : ) and pretty well actually. In this setup root privileges are required for dotool. I couldn't figure out how to unmute the microphone with alsa in the chroot environment but i was able to bridge over from termux using pulseaudio and sox. pulseaudio --start; sox -d -V0 -c1 -r16000 -t raw alpine-fs/root/fifo.raw [Ctrl-Z] ; bg; sudo ./exec-alp numen --audio=fifo.raw

~masq a day ago

Your project is brilliant by the way

~geb a day ago

That's really cool! Still a hack but maybe you could avoid the fifo by piping the audio to numen --audio=/dev/stdin? And thank you :)

~masq a day ago*

Well yes, it's a hack but it's getting cold outside and if i can change the music i'm listening to or taking notes without taking my hands out of my pockets this qualifies as a technological acme.

And the named pipe, albeit ugly, is still needed in this case i think because of chroot. I can't make your suggestion work

~geb REPORTED CLOSED 9 hours ago

Yeah, I'm so glad open-source speech recognition can be as good as it can now. And you're probably right about the pipe and chroot.

I'll mark this ticket resolved but feel free to message me wherever. I've started a list of cool things using numen (https://sr.ht/~geb/awesome-numen) and I'd totally add a script or blog post about termux+numen if you'd like to contribute. All the best!

Thanks John, and you. I'll keep an eye on your page and will help if i can.

In the meantime - unrelated, do you see a possibility to remove my email address from the issue tracker or at least obfuscate it in a way that it doesn't fall prey to spiders? I looked into my account settings and couldn't see any option. Did i miss anything?
