As far as I understood the main focus of badaix is developing the tool "snapcast" itself, not snapos, #10

This is nothing more than a small buildroot based Linux OS with pre installed snapclient or server.
I don't have the time to maintain this actively or release images for all of the different raspberry versions.
I recommend to build it by following the guide, or to use raspbian and install a snapclient or server deb package.

I'm a proficient Linux user, but not a programmer, distro or package maintainer. I'm also a user of Openwrt (also based on Buildroot).

But I have yet to find time to dabble with Buildroot and its ecosystem.
I understand its not the easiest one for beginners, but it shouldnt be rocket science either.

In the mean time I've seen a lot of things building upon Alpine Linux in the last times. PostmarketOS is one very interesting one.

The other day I was checking myMPDos, https://github.com/jcorporation/myMPDos and noticed that it also builds upon Alpine.

I then checked and saw that, https://pkgs.alpinelinux.org/packages?name=snapcast&branch=edge&repo=&arch=&maintainer=

Alpine linux itself provides stable well maintained snapcast packages for a plethora of architectures. They even provide both armv7h (raspberry 2) and even armhf (raspberry zero).

This is very interesting for the ones interesting and reusing (old) hardware, with the promise of long time support.

So I was just wondering if anyone has had any similar thoughts.
What are your ideas/comments about this ?

Is anyone here already using snapcast on a (minimal) Alpine setup ?
If so, how do you compare it to Snapos ?

Easier to maintain/update/customize ? Add extra multimedia tools ? How does it compare to something like Buildroot for less experienced users ?

Thanks in advance.

Hello! I've been testing out all the different Raspberry Pi systems available to approximate an "open source sonos", and I think your SnapOS might be the way to go! But I'm a novice and building an OS is a bit beyond me right now. I would love to flash one of your images though! :)

...to make the speakers in my kitchen a bit less shitty.

https://github.com/fuchsmich/snapos/blob/alsaequal/buildroot-external/README.md#alsaequal

This is asking about the buildroot files.
You have files for snapos_rpi_defconfig through snapos_rpi4_defconfig, do you have one for the zero or zero W or should the snapos_rpi_defconfig be used for these? Or do you not recommend using the zero/zero W as a client?

Is there anyway we can get updated instructions for compiling for openwrt? The current instructions don't seem to work. Specifically "ln -s /openwrt package/snapcast" doesnt allow make menuconfig to see snapcast as a package

Hi, i am trying to build snapOS for an RPi3, to try and reduce the vulnerabilities in my network, reduce attack surface etc.

I have built the images and flashed it successfully, now when i try and boot (after updating network details), i get the following warning:

Successfully initialized wpa_supplicant
Line 2: unknown global field 'ctrl_interface/var/run/wpa_supplicant'
Line 2: Invalid configuration line 'ctrl_interface/var/run/wpa_supplicant'
Failed to read or parse configuration '/etc/wpa_supplicant.comf'
FAIL

note: i ahve hand typed this, so there may be typo's.

Any help with what i am missing/doing wrong would be great.

thanks!

Would it be enough to change line 7 in https://github.com/badaix/snapos/blob/master/buildroot-external/package/snapcast/snapcast.mk#L7 to generate an image with snapclient 0.19?

After commit badaix/snapcast@0868ae1 ("Remove debhelper files") it's unable to build Snapcast for OpenWrt.

Those files arrived here in commit 380d13c 0a8e5b8 ("Add debian package").

Do you have any schedule finishing (merging) that debian branch? Are contributions (of OpenWrt packaging) welcome on debian branch?

Build Environment
OS: Ubuntu 21.04
GCC: 10.3.0 (Ubuntu 10.3.0-1ubuntu1)

I tried following the buildroot instructions, but the build would fail in error:

Should I be compiling this with an older version of gcc?

...and how do I disable udhcpc?

# alsamixer

The environment variable TERM is set to xterm-256color:

changing TERM to xterm-color fixes the issue and should be default

Hello

I tried to compile snapcast for OpenWRT 23.05.0 and I faced an error

Fortunatly it was at the end, during install step of Makefile.

Here is a dirty workaround :

# Copy snapclient.default to files
cp snapos/debian/snapclient.default snapos/openwrt/snapcast/file
# adjust permission
chmod 0755 snapos/openwrt/snapcast/file/snapclient.default

And you'll have to change line 112 on Makefile (snapos/openwrt/snapcast/Makefile) (the original is commented)

    # $(INSTALL_BIN) $(PKG_BUILD_DIR)/debian/snapclient.default $(1)/etc/default/snapclient
    $(INSTALL_BIN) ./files/snapclient.default $(1)/etc/default/snapclient

Thanks for your marvelous work, it allows to keep my pogoplug up to date !

Bests

Hi! I was wondering how well does snapos handle SD card problem of exceeding maximum ammount of writes to the FS? Is it possible to make the FS read-only?

Hi guys!
Nice work, congrats!

Please I'm trying to put snapcast client inside one of my openwrt boxes. After follow the guide and start compilation process it stops showing this:+

As far I can see it is messing with aixlog but can't figure out where the problem is. Please any help on how to debug gurther this issue?
Regards,

Thanks for this great piece of software!

Currently, snapclient on openwrt installs a config file in /etc/default/snapclient. This file is lost on OpenWRT upgrade (sysupgrade). By moving the config file to /etc/config, it gets included and restored through the OpenWRT config backup mechanism.
Alternatively, a symlink from /etc/default/snapclient could be made to /etc/config/snapclient.

Hello,

I tried to build snapclient for OpenWrt with the two methods: "OpenWrt build system setup" and "Alternative: Using OpenWRT-SDK"

Both fail because, if I get it correctly, "https://git.xiph.org" moved to "https://gitlab.xiph.org/xiph"

here is my " make -j1 V=sc " output:

Thank you for your work!

i wanted to upgrade my WiP SnapOS build with the today released snapcast 0.22 version,but build fails and i am not the programmer guy to know, whats the issue. Perhaps you can give me a hint or update the package files for 0.22 ?

Opus is a codec that offers a great compromise between quality and latency.

I suggest adding it to the list of packages the Snapos builds, for instance adding BR2_PACKAGE_OPUS to package/snapcast/Config.in.
(BR2_PACKAGE_OPUS_TOOLS might be the one needed, I need to check)

It uses very little extra space and makes the built-in snapcast more robust, I think.

Thanks!
