twonkymedia server on fresh installed debian lenny failure

hi all,

i installed Linux ARM little endian glibc 2.2.5 on my qnap ts-209 running debian (lenny).

Code: Select all

chmod 700 twonkym* cgi-bin/* plugins/*
./twonkymedia.sh start
Starting /usr/local/TwonkyVision/twonkymedia ... ./twonkymedia.sh: line 97: /usr/local/TwonkyVision/twonkymedia: No such file or directory

Code: Select all

file TwonkyVision/twonkymedia
TwonkyVision/twonkymedia: ELF 32-bit LSB executable, ARM, version 1, dynamically linked (uses shared libs), for GNU/Linux 2.4.3, stripped
i found out that there is a missing glibc version

installed is

Code: Select all

strings /lib/libc.so.6 | grep GLIBC
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_PRIVATE
quick an dirty i did a

Code: Select all

cd /lib
ln -s ld-2.7.so ld-linux.so.2
try starting

Code: Select all

any ideas, how i get the missing (old) glibc libraries installed?

Here some detailed information about the incompatibility of twonkymedia-armel-glibc-2.2.5-4.4.11-20090108.zip and Debian GNU/Linux 5.0 "lenny".

TwonkyMedia server is compiled against a old LIBC version which is not supported by LENNY anymore. Which interface version are supported by LIBC can be checked with the following command.

# apt-get install binutils
# objdump -p /lib/libc.so.6
...
Version definitions:

Now check the LIBC versions TwonkyMedia server requests.

# objdump -p /usr/local/twonkymedia/twonkymediaserver
...

private flags = 2: [APCS-32] [FPA float format] [has entry point]
Until TwonkyMedia is build agains these new LIBC version we have to install a LIBC environment which satisfy this API version. With Debian GNU/Linux 4.0 "etch" this requirements are solved. To install a ETCH on LENNY do the follwoing steps.

# apt-get install debootstrap
# debootstrap --arch=arm etch /etch-root http://ftp.de.debian.org/debian/

Now we have a chroot environment installed in /etch-root including an older LIBC.

# objdump -p /etch-root/lib/libc.so.6

This version of LIBC support the required API version by TwonkyServer. Extract now the TwonkyServer ZIP archive within the new chroot environment.

# mkdir /etch-root/usr/local/twonkymedia
# cd /etch-root/usr/local/twonkymedia
# unzip /root/twonkymedia-armel-glibc-2.2.5-4.4.11-20090108.zip
# chmod 700 twonky* cgi-bin/* plugins/*
# cd /root

We are now ready to start the TwonkyMedia server within the chroot environment. But there are two other things we have to prepare. First, the /proc directory have to be seen within the chroot envirionement. This can be done by the following command.

# mount --bind /proc /etch-root/proc

Second. Our media libarary is outside the chroot directory. We have to mount the media library into the chroot directory with the same mount --bind command.

# mount --bind /home /etch-root/home

We are now ready to start the TwonkyMedia server within the chroot environment.

# chroot /etch-root /usr/local/twonkymedia/twonkymedia.sh start

Setup the TwonkyMedia server to search within the /home directory and you are ready.

A script make it easier to handle.

Code: Select all

#!/bin/sh

set -e

action="$1"

case "$action" in
  *start)
    mount | grep -q " on /etch-root/proc " || mount --bind /proc /etch-root/proc
    mount | grep -q " on /etch-root/home " || mount --bind /home /etch-root/home
   ;;
esac

chroot /etch-root /usr/local/twonkymedia/twonkymedia.sh $action || true

case "$action" in
  stop)
    mount | grep -q " on /etch-root/proc " && umount /etch-root/proc
    mount | grep -q " on /etch-root/home " && umount /etch-root/home
  ;;
esac
I hope this help :D

Great write-up, harrysun.

An alternative solution is to use the uClibc version.

0) Download the ARM little-endian uclibc twonky from the unsupported twonky distributions page

1) Download uClibc 0.9.28-3 from http://free-electrons.com/pub/toolchain ... -3.tar.bz2 (direct link: http://free-electrons.com/pub/toolchain ... -3.tar.bz2) and extract into /usr/local/uclibc-0.9.28-3 per the instructions on the page. Do this as root:

Code: Select all

mkdir -p /usr/local/uclibc-0.9.28-3
cd /usr/local/uclibc-0.9.28-3
wget http://free-electrons.com/pub/toolchains/uclibc/0.9.28-3/arm-linux-uclibc-0.9.28-3.tar.bz2
bunzip2 -c arm-linux-uclibc-0.9.28-3.tar.bz2 | tar xvf -
2) Modify the twonkymedia.sh script to include the line LD_LIBRARY_PATH=/usr/local/uclibc-0.9.28-3/arm/lib. Do this using an editor, or:

Code: Select all

cd /to/wherever/you/installed/twonkymedia/
printf '1i\nLD_LIBRARY_PATH=/usr/local/uclibc-0.9.28-3/arm/lib\n.\nwq!\n' | ex twonkymedia.sh
This is the solution I've gone with. I'm not sure how Twonky internally launches new processes; if it comes to the point where Twonky supports transcoding and my transcoding tool is compiled against glibc, I don't know if I'll be able to tell twonky to not inherit parent process environment (and therefore unset LD_LIBRARY_PATH or have it set to /lib etc)

Just got a SheevaPlug today and came across this same problem. However I can't get the uclibc trick to work. Has anything changed to stop it working?

EDIT: Found out the build for Linkstation Pro works without any problems....

if I do file on it:

Hi, I have a ARM processor running inside my Wester Digital My Book World Edition.
I want to install Twonky glibc little endian.

# strings /lib/libc.so.6 | grep GLIBC

Code: Select all

I am not shure if this warning is somehow important... but anyway.

As you can see, I also need some missing glibc libraries.
I have no clue where I can get the. I have no debian based linux distro. There is no debootstrap available on this linux...

Any ideas, how i get the missing (old) glibc libraries installed?
