meta: bernard
meta-demo: master (bbbba2bb74846db9b2505089522b60d97ea0ea70)

OE Build Configuration:
BB_VERSION        = "1.11.0"
METADATA_BRANCH   = "bernard"
METADATA_REVISION = "82af8b9fb6d6d1439943fd15b8a75c0e663e4a45"
TARGET_ARCH       = "mips"
TARGET_OS         = "linux"
MACHINE           = "routerstationpro"
DISTRO            = "poky"
DISTRO_VERSION    = "0.9+snapshot-20110321"
TARGET_FPU        = ""


I built poky-image-mediatomb for the Router Station Pro today, and after getting a tftpd server setup to boot the thing, I ran into this:

root@routerstationpro:~# /etc/init.d/mediatomb restart
Restarting upnp media server: /usr/bin/mediatomb: error while loading shared libraries: libjs: cannot open shared object file: No such file or directory
mediatomb.


I noticed that libjs.so does exist in /usr/lib, so I tried the following:

root@routerstationpro:~# LD_PRELOAD=/usr/lib/libjs.so mediatomb

MediaTomb UPnP Server version 0.12.1 - http://mediatomb.cc/

Get's further, but something still isn't quite right.

The library looks sane:

# file /usr/lib/libjs.so
/usr/lib/libjs.so: ELF 32-bit MSB shared object, MIPS, MIPS32 version 1 (SYSV), dynamically linked, with unknown capability 0x41000000 = 0xf676e75, with unknown capability 0x10000 = 0x70401, stripped

Hmm, I seem to recall this from the Laverne demo - Mark, did we not fix this?
Can you remember the workaround you used in Cambridge?

Comment 2 Joshua Lock - Disabled 2011-03-22 05:18:57 UTC

We had incorrectly linked libraries on PPC in 0.9 which iirc resulted in similar errors. http://bugzilla.pokylinux.org/show_bug.cgi?id=515

Comment 3 Joshua Lock - Disabled 2011-03-22 07:45:48 UTC

Per #515 running ldconfig on the device after boot I can then start mediatomb. However it still segfaults...

Comment 4 Darren Hart 2011-03-22 22:24:07 UTC

Did we change the version of Mediatomb or libjs since the 0.9 demo?

Comment 5 Kevin Tian 2011-03-23 01:47:29 UTC

it looks that this does be machine specific. On my eMenlow board, mediatomb is launched successfully FYI.

Comment 6 Joshua Lock - Disabled 2011-03-23 08:25:04 UTC

I guess mediatomb hasn't seen much build/test on MIPS. Even if I revert to the 0.9 demo and build an image with mediatomb for the routerstationpro I get a segfault on launch...

Comment 7 Darren Hart 2011-06-30 15:39:40 UTC

Needs an owner.

Comment 8 Darren Hart 2012-08-20 21:23:49 UTC

I doubt Shane is still looking at this. As a "low" it doesn't need to be scheduled. I would suggest removing the target milestone instead of just bumping it along every milestone.

Comment 9 Ross Burton 2013-09-10 14:36:05 UTC

meta-dlna is dead now.
