Scripts for building external binaries that Asset Bank depends on: Ghostscript, ImageMagick and ffmpeg.

The current versions of these scripts are only for use with Debian 7.0 (Wheezy).

On any machine that will be used to build these tools, run:

./build-setup

this only needs to be run once, not every time you do a build.

They are in the same script because ImageMagick depends on Ghostscript.

Download ghostscript-9.06.tar.gz and ImageMagick-6.8.9-0.tar.xz to ~/software/.

Run:

./build-ab-gs-im

Download ffmpeg-1.0.9.tar.bz2 to ~/software/

Run:

./build-ab-ffmpeg

Run:

./deploy-setup

Untar the prebuilt binaries into /usr/local/assetbank.

Set the following environment variables (either in your user's shell or in /etc/default/tomcat6):

LD_LIBRARY_PATH=/usr/local/assetbank/ffmpeg/lib
PATH="/usr/local/assetbank/ffmpeg/bin:/usr/local/assetbank/ghostscript/bin:/usr/local/assetbank/imagemagick/bin:$PATH"
export LD_LIBRARY_PATH PATH

/usr/local/assetbank/{ffmpeg,ghostscript,imagemagick} are symlinks to allow easy upgrades without Tomcat restarts on Asset Bank servers.

These scripts build dynamic, not static binaries because static linking against glibc is not recommended and it is hard to get an autoconf-based build to link dynamically against glibc and statically against everything else. Basically, static linking on GNU/Linux seems to be deprecated these days.

The fact that the binaries are dynamically linked means that they need various libraries to be installed on the systems that they run on. More thought needs to be put into how to arrange that, although one quick way would be to run the 'setup' script on all target hosts; the 'apt-get build-deps' steps should install all the required libraries (along with many packages that are not needed, e.g. -dev packages).
