Pianobar and Openwrt #293

Closed jliu83 closed 12 years ago

jliu83 commented 12 years ago

I downloaded the source and compiled for Openwrt Backfire 10.03. While the compilation and installation was successful, when I run the program, it does not work.

When I start the program, it says Segmentation Fault and exits tot he prompt. Any idea what is going on? What would I have to do to get some debug output and how can I contribute to porting this over to the Openwrt distro?

Thanks, -J

PromyLOPh commented 12 years ago

Compile pianobar with debug symbols (either gmake debug or CFLAGS=-g) and create a backtrace[1].

jliu83 commented 12 years ago

I will try it out tonight and let you know.

jliu83 commented 12 years ago

gdb is too large as of right now to put on the router. Need to get gdb server to work first. Will keep you updated.

jliu83 commented 12 years ago

I was able to get gdbserver working and I created a back trace. I didn't include the full one, but this seems to be the culprit:

Program received signal SIGSEGV, Segmentation fault. 0x2ad12f40 in cipher_setkey () from /home/jianyi/git/backfire_10.03/scripts/../staging_dir/target-mipsel_uClibc-0.9.30.1/root-brcm-2.4/usr/lib/libgcrypt.so.11

Do you think this is caused by differing version of libgcrypt? I can include the full trace if that helps.

PromyLOPh commented 12 years ago

Do you think this is caused by differing version of libgcrypt? Which version are you using right now?

I can include the full trace if that helps. Yes, please post the full trace.

jliu83 commented 12 years ago

I am still learning the ins and outs of Linux so please bear with me if my responses are not complete. Let me know if these outputs are what you are looking for. Thanks a lot for such a great program. I use it all the time on my work machine, but I'd like to put it on an embedded distro.

Hm, are you using the latest pianobar release (2012.06.24) or git HEAD? I fixed an issue related to gcrypt in 96db841a16670b52fa462337c657c6dc6bd2844a.

jliu83 commented 12 years ago

Definitely the latest. Compiles and works fine on a Beagleboard (ARMH arch). However doesn't quite work on the MIPS. Any other ideas?

PromyLOPh commented 12 years ago

Any other ideas? Yes. Currently the return value of gcry_cipher_open is not checked (in piano.c:PianoInit), so it could return an error if the cipher is not supported. Here’s a patch that prints an error message: https://gist.github.com/3207162

jliu83 commented 12 years ago

I'll try the patch tonight.

PromyLOPh commented 12 years ago

Interesting, the stack trace looks different. Do you get a different trace for every crash? That would indicate that something else (i.e. not pianobar) is the problem – lack of RAM (segfault), perhaps?

jliu83 commented 12 years ago

Hmm.. How much RAM do you think is needed? If that's the case, then I guess this should be closed.

PromyLOPh commented 12 years ago

top says: virt: 57124, res: 1764, shr: 208. That should be about 2MB RAM usage. Not sure how much RAM embedded devices have these days… Note that I’m just guessing – the problem could be somewhere else too ;)

jliu83 commented 12 years ago

Well the router has 16 MB. I'll dig deeper on my own. Thanks for all the help. I guess at least I learned how to create a backtrace.

chaseadam commented 11 years ago

jliu83, did you find a solution?

I am running into this issue as well even with the latest 2012.12.01. I am on a similar platform mipsel. Not sure where my SIGSEV is coming from because I can't figure out how to include the debugging symbols yet in the openwrt build system.

Running same version of gcrypt (1.5.0).
