I usually do most of my work these days on an Air. While its decent, it is rather dinky spacewise, and I tend to keep it empty of music so I have (barely) enough space for my dev stuff, and various embedded cross compile environments.<\/p>\n

I still like listening to music though, so I keep that on secondary and even tertiary storage. This typically is one of the fine HP N36L \/ N40L NAS devices that I’m fond of buying. I have a few HP N36\/N40L nas boxen in various places, some of which contain my music, but most of which contain backups, onsite, and offsite, as you can never be too careful!<\/p>\n

I know this quite intimately, as the very machine I’m typing this on had a catastrophic SSD failure only a week ago.
\nLuckily I didn’t lose too much work!<\/p>\n

Enough with the background, and back to the plot.<\/p>\n

As I was saying, I needed some tunes to harass the staff with<\/span> listen to at work.<\/p>\n

I looked at a couple of solutions, and decided on forked-daapd, as that allegedly could share music to iTunes from the NAS music folder without too many headaches.<\/p>\n

Most instructions were of the sort:<\/p>\n

apt-get install forked-daapd<\/p>\n

pico \/etc\/forked-daapd.conf<\/p>\n

[edit music folder, save file]<\/p>\n

\/etc\/init.d\/forked-daapd restart<\/code><\/p>\n

In my case it didn’t work.
\nIt also didn’t really give much clue that it wasn’t working, and their website didn’t have much to go on.
\nI looked at compiling from scratch, but the guy making it uses Clang and Java stuff to build, and it just looked like too much hassle.<\/p>\n

So, I had to troubleshoot even though I didn’t really want to spend the time.<\/p>\n

My initial issue was something like the below:<\/p>\n

forked-daapd wouldn’t run successfully (but it also didn’t complain, sigh). I could see that it wasn’t running on any port specified, and checking kern.log showed it was crapping out silently.<\/p>\n

Mar 20 21:03:09 officenas kernel: [ 3392.026612] forked-daapd[9848] trap invalid opcode ip:7f8d8772958e sp:7f8d8176bf60 error:0 in libdispatch.so.0.0.0[7f8d87722000+c000]<\/code><\/p>\n

Running it in the foreground showed it was having issues creating the mDNS bits.<\/p>\n

mdns: Failed to create service browser: Bad state<\/code><\/p>\n

This eventually worked out to editing \/etc\/nsswitch.conf, adding the following to the host lines:<\/p>\n

hosts: files mdns4_minimal dns mdns4<\/code><\/p>\n

then restarting avahi <\/p>\n

\/etc\/init.d\/avahi-daemon restart<\/code> <\/p>\n

This got me past the bad state error, but then it was bombing out with a missing symbol avl_alloc_tree error.<\/p>\n

I did an strace on the thing and found it was looking for libav under \/lib vs under \/var\/lib<\/p>\n

This was also documented here – http:\/\/blog.openmediavault.org\/?p=552&cpage=1#comment-8376<\/a>, although sadly not until I found out myself.<\/p>\n

Looks like the zfsonlinux is the culprit here, as that puts libav files in that folder. Tsk tsk.<\/p>\n

I removed those libav files – rm \/lib\/libav* ****as I know what I’m doing****<\/strong> (don’t randomly erase stuff unless you’re 3000% sure!), and sure enough, forked-daapd started up, and started blatting tons of output to the logs in a happy manner.
\niTunes was also finally happy, and could see my music. Yay.<\/p>\n

Took me about 2 hours to figure out sadly, but at least I sorted it out.<\/p>\n

Hopefully this will save someone else the headache when they google for the error(s)!<\/p>\n","protected":false},"excerpt":{"rendered":"
