Disable Auto-Update for Thunderbird and Firefox

Mozilla has decided to speed up the release cycle of Thunderbird and Firefox. This is all good except that it often breaks Add-ons. If you want to do the update manually, when you feel like it or when you know the all important plugins you use are compatible with the new version, you may follow the instructions to disable automatic update of Thunderbird and Firefox. Disabling Automatic Update in Firefox Type about:config in the address bar and press Enter. You should get a page trying to scare you off with a message starting with “This might void you warranty!”, just click “I’ll be careful I promise!“. Then in the Filter filed type app.update.enabled. It should be set to true, double-click on the line to set it to false. Disabling Automatic Update in Thunderbird On the top menu, click on Tools->Options to enter the Options window, then click on Advanced and […]

Xibo Digital Signage on ARM (Beagleboard / Overo)

Xibo (pronounced eX-E-bO) is an open source, multi-display, multi-zone, fully scheduled digital signage solution written in Python (there is also a dotnet version). This is a client /server solution that can run on Windows or Linux. If you are not familiar with Xibo you can visit http://xibo.org.uk/ or/and read my introduction XIBO: An Open Source Digital Signage Server/Client. Since I had not seen digital signage solution running on low cost ARM development platform such as Beagleboard, Pandaboard or Origen, I decided to give the Xibo python client a try using qemu to emulate Gumstix Overo COM (OMAP 3530). Porting Xibo to ARM could provide several benefits compared to x86 platform: Lower hardware cost Lower power consumption (and electricity bill) Smaller form factor allowing easier integration in displays and in transportation (e.g. buses, subway trains). Easier to implement new digital signage features such as touch screen support, 3G connectivity, location based […]

Cross Compiling libavg for ARM

libavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++. Bear in mind that are many dependencies with libavg 1.6. I have not built all the libraries required, but instead simply taken the pre-built binaries and header files in the qemu overo image and copied the files as follows: mkdir mnt sudo mount -o loop,offset=$[106496*512] overo_sd_alip.img mnt mkdir ~/edev/beagleboard/libs/lib -p mkdir ~/edev/beagleboard/libs/include cp mnt/usr/lib/* ~/edev/beagleboard/libs/lib/ -rf -d cp mnt/lib/* ~/edev/beagleboard/libs/lib/ -rf -d cp /mnt/usr/include/* ~/edev/beagleboard/libs/include -rf -d sudo umount mnt The -d flag skips the symlink, so we need to recreate then for all library so that the compiler can find libname.so instead of libname.so.12. Save the following scripts to symlinks.sh:

#!/bin/sh
liblist=`ls *.so.??`
for f in $liblist
do
  echo $f
  fileres=`echo $f | sed 's/\..\{2\}$//'`
  ln -s $f $fileres
done
liblist=`ls *.so.?`
for f in $liblist
do
  echo $f
  fileres=`echo $f | sed 's/\..\{1\}$//'`
  ln -s $f $fileres
done

#!/bin/sh

liblist=`ls *.so.??`

for f in $liblist

echo $f

fileres=`echo $f | sed 's/\..\{2\}$//'`

ln -s $f $fileres

done

liblist=`ls *.so.?`

for f in $liblist

echo $f

fileres=`echo $f | sed 's/\..\{1\}$//'`

ln -s $f $fileres

done

and run it where the arm libraries are located (in my case in /home/jaufranc/edev/beagleboard/libs/lib, /home/jaufranc/edev/beagleboard/libs/lib/arm-linux-gnueabi and /home/jaufranc/edev/beagleboard/libs/lib/mesa). This will create symlinks for most libraries, but not all. Some will still […]

Cross-Compiling Mesa 3D Graphics Library for ARM

Mesa is an open-source implementation of the OpenGL specification that can be used for software emulation or complete hardware acceleration for modern GPUs.The Mesa library is used by a variety of games (e.g. Quake 2.3), libraries (e.g PyOpenGL), science and technical applications and utilities (e.g. xscreensaver). MesaLib requires X11 libraries. I’ll assume those are already cross-compiled here. For this build, I used pre-built X11 libraries found in ALIP (ARM Internet Platform) binaries. I used the method described here and copied the libs in /lib and /usr/lib and header files in /lib/include found in the qemu overo image respectively to /home/jaufranc/edeve/beagleboard/libs/lib and /home/jaufranc/edeve/beagleboard/libs/include. make sure you use the “-d” with cp to avoid copying the symlinks or some symbolic links would point to x86 binaries or files that do not exist. Here are the instructions to cross-compile MesaLib 7.11 for ARM using arm-linux-guneabi-gcc: Download the latest version of Mesa source code: […]
