Hi there,
I’ve updated from 1538 to 1586 on my SPARC/Solaris 9 machine, but I experience a few problems. (The reason for updating was some spurious crashes). mt-daapd starts up, does it scan, and gets ready. I can access the user interface via a web browser and change settings etc., but as soon as I want to play a song from within iTunes (on Mac) I get a segmentation fault on the server. (In fact, I also get a seg. fault if I try to do something in the web interface when the file scan is still running). Running mt-daapd in GDB in order to get a stack trace doesn’t work as it simply won’t run that far as that I could do anything with iTunes, mt-daapd seems to get stuck at some point when executed within GDB (see below). Any ideas? Thanks!

(gdb)well, the errors during db upgrade/scan are alright, there seems to be some problem with renzdezvous.
What are your compile options? 😉you’ll want to get gdb to ignore signals (ie let the mt-daapd signal handlers deal with them)
i believe the syntax is something like:
handle SIGPIPE ignorererun and see how you go
rayThanks for your quick responses.
I’ve now set GDB to ignore SIGPIPE (handle SIGPIPE nostop ignore). Now I can run the server within GDB (still, for some mysterious reasons, sometimes GDB is put in the background after a short while and only becomes active again after I get it back into the foreground with fg %1).
mt-daapd seems to run for a while, I can use the web interface, but it stops working as soon as I click on any song in the iTunes shared resource. Ok, having said this and having this checked over again, this is rather weird. Killed GDB and mt-daapd, started everything up again, and I got somewhat further. Again, killed everything and started up everything again it appears to work. The only change I am aware of is that I have waited until all file scanning activity had ceased, before I accessed the iTunes shared resource.
BTW, the options of “configure” are –enable-sqlite3, compiler options are -g -O2.
I’ll check again, maybe I can narrow down the situation when it works and when it doesn’t.
Cheers,
Bjoern
Here’s some additional info. I still haven’t found out what to do to make it crash (or actually to avoid this), sometime it works, but not always. If it gets stuck, however, this is the last output I can see in the GDB window.
Cheers,

Returning status -1I don’t have access to a sparc solaris box that I can handily use, but I don’t think it’s an endian issue or an alignment issue, since it works okay on ppc, mips, arm, etc.
I’ll try and replicate it on opensolaris and see if that gets me anywhere. Oh… and if you could get it to crash in gdb and get a backtrace, that would be really really helpful.
