Arch Linux User Repository

@keithspg: Any version lower than the current one in the arch repo should work.

In the meantime upstream has promised to release a new version within about a week: https://github.com/badaix/snapcast/issues/1100

Tried it today and get the same error on armv7h (RPi). Is there a version of boost we can build that will allow it to build?

@gbr: Turns out that this is an upstream issue. The latest released snapcast version does not compile with the current boost version. Upstream has alread been patched, but the fix has not been released yet. I'll ask if they can release a new version.

PS: While I really do appreciate that issues are reported, please only report errors that are reproducible using the bare makepkg command. I've wasted enough time trying to reproduce issues that turn out to be related to helper tools like paru.

Does not build for me:

I believe pkgconfig should be in the mandatory dependencies.

And why do you believe that? pkgconf is part of the base-devel group, and following the docs it should not be explicitly included as makedepends.

Thanks for making the package!

@m040601: This gcc11 patch is unrelated. That code is now in 0.26.0 itself. Please report upstream as this is indeed most likely an out-of-memory issue.

I wonder if anyone can give me any tips or insight before I try to report my problem to upstream Snapcast.

I've been running Archlinux (ARM) and compiling Snapcast on my 1GB memory humble little Raspberry Pi 2 1.1 (32 bit armv7h) for 2 years. Until version 0.26 had no problems. It always took aaaaaaages to compile this C++ thingy, but in the end it bravely managed to do it. Running MPD and Snapcast with Opus encoding was also very smooth, and the CPU and RAM has always been more than enough.

With the latest version 0.26 in December, I'm stuck. I can't finish compiling it, without running out of memory apparently. Tried already several times. It's the exact same system I've been running for 2 years. But somehow I cant get past 15% in the compilation process and makepkg aborts with:

boost::asio::wait_traits<std::chrono::_V2::steady_clock> > >::heap_entry> > >’ changed in GCC 7.1

    Aborting...

Sometimes I get a kernel "oom kill" thingy. The system runs out of memory, and the kernel aborts the process and reboots.

alarmpi kernel:

cc1plus invoked oom-killer: gfp_mask=0x100cca(GFP_HIGHUSER_MOVABLE), 
CPU: 1 PID: 16110 Comm: cc1plus Tainted: G         C        5.10.83-1-r>

and

oom_reaper: reaped process 16110 (cc1plus), now anon-rss:0kB, file-rss:>

I have very little understanding of C++, compilation processes etc. But the first thing that occurred to me, is that, with version 0.26, maybe somehow the requirements of Snapcast have changed, are beefier now, and this hardware can't cope with it now.

Tried to shut down all the other non necessary services, and tried over and over to no avail.

Is this a plausible explanation ?

But before I report this to Snapcast upstream, I want to be 100% sure, that it's not the PKGBUILD fault.

I noticed something with this PKGBUILD here on AUR. The latest changes to the PKGBUILD removed this line:

- "gcc11-fix.patch"

So this patch is no longer being applied as was in version 0.25. I dont know what the patch was for but:

Could it somehow be related to this patch (or lack of it)  ?

Thanks in advance.

PS: Maybe related ? I saw this on Snapcast issues:

About the debian armhf package, https://github.com/badaix/snapcast/issues/960

...So the gcc and c++ libs are still needed in a more recent version. I guess because Snapcast 0.26
requires C++17 instead of C++11.

@cgirard: I've been trying to get exact solution upstreamed for quite a while now. See upstream issue: https://github.com/badaix/snapcast/issues/486

You're probably right that, in the meantime, I should change the text in the install file to refer to changing the location of the fifo rather than trying to work around the problems with the default location in /tmp

Hi, instead of advising of disabling protected FIFOs, it would be probably a better idea to just advise to use /run/snapserver/snapfifo as you even care to create /run/snapserver
