Compiling MediaTomb for the Drobo

This guide assumes that you already have a cross-compiling environment setup such as the one described in Setup a Cross-Compile Environment for Drobo. I used this article Building MediaTomb for the Drobo using Ubunutu to get my system working and to create this guide.

This guide was created using MediaTomb 12.1 for Drobo FS.

Prepare MediaTomb Build Environment

# Activate/Enter the chroot

sudo schroot -c drobofs -d /root

# create a directory for downloaded archives (if you didn't already do so)

mkdir -p /root/download

# create mediatomb build directory (I use the application name)

mkdir -p /root/mediatomb

# create directory for resulting binaries (I use a target directory for this application build)

mkdir -p /root/mediatomb/arm

# Define the following environment variables for the application build directory

export CFLAGS="-I/root/mediatomb/arm/include -march=armv5te"
export CPPFLAGS=${CFLAGS}
export LDFLAGS="-L/root/mediatomb/arm/lib -Wl,-rpath -Wl,/mnt/DroboFS/Shares/DroboApps/mediatomb/lib"
export CC=arm-none-linux-gnueabi-gcc

File

Download File from http://www.darwinsys.com/file/. Note: The site admin removed the 4.24 version of file and I had issues compiling the latest versions, but download 4.24 from my link provided below.

# Download code
wget -P ~/download ftp://ftp.sunfreeware.com/pub/freeware/SOURCES/file-4.24.tar.gz
 
# Extract code 
cd ~/mediatomb
tar xfz ~/download/file-4.24.tar.gz
cd file-4.24

# Edit magic/Makefile.am in vi or some other editor

# Change line 224 from
${MAGIC}: $(EXTRA_DIST) $(FILE_COMPILE)
# to
${MAGIC}: $(EXTRA_DIST)

# generate build scripts
aclocal
autoheader
autoconf
libtoolize
automake
 
# configure, build, and install
./configure --host=arm-none-linux-gnueabi --prefix=/root/mediatomb/arm
make
make install

libexif

Download libexif from http://libexif.sourceforge.net.

# Download code
wget -P ~/download http://downloads.sourceforge.net/project/libexif/libexif/0.6.19/libexif-0.6.19.tar.gz
 
# Extract code 
cd ~/mediatomb
tar xfz ~/download/libexif-0.6.19.tar.gz
cd libexif-0.6.19
 
# configure, build, and install
./configure --host=arm-none-linux-gnueabi --prefix=/root/mediatomb/arm
make
make install

TagLib

Download TagLib from http://developer.kde.org/~wheeler/taglib.html to ~/download/, I used taglib-1.6.3.tar.gz for this guide.

# Extract code 
cd ~/mediatomb
tar xfz ~/download/taglib-1.6.3.tar.gz
cd taglib-1.6.3
 
# configure, build, and install
./configure --host=arm-none-linux-gnueabi --prefix=/root/mediatomb/arm
make
make install

id3lib

id3lib is available from http://id3lib.sourceforge.net/; however, since TagLib is being used it is not needed. See the mediatomb documentation for details on using id3lib if needed.

libjs - SpiderMonkey

Download SpiderMonkey from http://ftp.mozilla.org/pub/mozilla.org/js/.

# Download code
wget -P ~/download http://ftp.mozilla.org/pub/mozilla.org/js/older-packages/js-1.5.tar.gz
 
# Extract code 
cd ~/mediatomb
tar xfz ~/download/js-1.5.tar.gz
# be tidy and rename the directory so the version is obvious
mv js js-1.5
cd js-1.5/src

# run make, this will fail on the first attempt
make BUILD_OPT=1 -f Makefile.ref CC=arm-none-linux-gnueabi-gcc LD=arm-none-linux-gnueabi-ld

# first copy jscpucfg to the target drobo and execute it. to generate jsautocfg.h

# NOTE: run this on the Drobo, NOT on the build system
./jscpucfg > jsautocfg.h

# copy the resulting jsautocfg.h back to your build system to replace the 0 byte version

# repeat make, should run successfully

make BUILD_OPT=1 -f Makefile.ref CC=arm-none-linux-gnueabi-gcc LD=arm-none-linux-gnueabi-ld

# there is no install target, so manually install

# from dir: js-1.5/src
mkdir /root/mediatomb/arm/include/smjs/
cp *.{h,tbl} /root/mediatomb/arm/include/smjs/
cp Linux_All_OPT.OBJ/*.h /root/mediatomb/arm/include/smjs/
cp Linux_All_OPT.OBJ/js /root/mediatomb/arm/bin/
cp Linux_All_OPT.OBJ/libjs.so /root/mediatomb/arm/lib/

Build Mediatomb

Download MediaTomb from http://mediatomb.cc/pages/download#source_code.

# Download code
wget -P ~/download http://downloads.sourceforge.net/mediatomb/mediatomb-0.12.1.tar.gz
 
# Extract code 
cd ~/mediatomb
tar xfz ~/download/mediatomb-0.12.1.tar.gz
cd mediatomb-0.12.1

make
make install

Mediatomb Configuration Summary

The resulting mediatomb configuration would be the following:

sqlite3               : yes
mysql                 : disabled
libjs                 : yes
libmagic              : yes
inotify               : yes
libexif               : yes
id3lib                : disabled
taglib                : yes
libmp4v2              : disabled
ffmpeg                : disabled
ffmpegthumbnailer     : missing
lastfmlib             : disabled
external transcoding  : yes
curl                  : no
YouTube               : disabled
libextractor          : 
db-autocreate         : yes

Package the DroboApp

The binaries creating during this build are now installed to /root/mediatomb/arm which can be packaged and transferred to the Drobo. Only the output bin, lib/*.so*, share/file, and share/mediatomb directories are required at runtime; so the other files can be excluded during transfer and packaging.

We need to create a startup script for the DroboApp. For the Drobo FS, the script is named service.sh and could look similar to the following sample:

#!/bin/sh
#
# mediatomb
 
. /etc/service.subr
 
prog_dir=`dirname \`realpath $0\``
 
# define DroboApp name and version 
name="mediatomb"
version="0.12.1"
# also define the admin port since mediatomb would randomly assign it otherwise
port=49152
 
pidfile=${prog_dir}/mediatomb.pid
logfile=${prog_dir}/mediatomb.log
 
# define the location of the shared libraries built for mediatomb
# runtime library path was set during compile, so this should not be needed
libdir=${prog_dir}/lib
if [ -n ${libdir} ]; then
	export LD_LIBRARY_PATH=${libdir}
fi
 
export MEDIATOMB_DATADIR="${prog_dir}/share/mediatomb"
export MEDIATOMB_MAGIC_FILE="${prog_dir}/share/file/magic"
 
# define the start command
start()
{
	# launch the mediatomb daemon using the specified port and some other options
	${prog_dir}/bin/mediatomb -d -m ${prog_dir} -f config -e eth0 -p ${port} \
		-P ${pidfile} --logfile ${logfile} >> ${logfile} 2>&1
}
 
# this standard stuff for service scripts
case "$1" in
start)
	start_service
	;;
stop)
	stop_service
	;;
restart)
	stop_service
	sleep 3
	start_service
	;;
status)
	status
	;;
*)
	echo "Usage: $0 [start|stop|restart|status]"
	exit 1
	;;
esac
