HowTo: Compile MediaTomb with JavaScript support on Ubuntu 11.04

--- UPDATE ---
Since Ubuntu 11.10 (Oneiric Ocelot) is now available, it was time for an update:
HowTo: Compile MediaTomb with JavaScript support on Ubuntu 11.10 Oneiric Ocelot
--- UPDATE END ---

Since some time in Ubuntu MediaTomb is compiled without JavaScript support. JavaScript support is needed for example to handle/import playlists. So I spent some time on the net looking for a howto. The best I found was this one targeted to Ubuntu 10.04.

To make long stories short: The problem is with SpiderMonkey, the Mozzila JavaScrip engine. MediaTomb needs a header called jsapi.h to compile. As Natty comes with packages providing these headers (libmozjs185-1.0, libmozjs185-dev, xulrunner-2.0-mozjs) I gave it a try, but I didn't manage. I also followed Gabriel's hints on how to build and install SpiderMonkey from source, but did still not succeed. 

After a little more of research I finally managed to build MediaTomb on my Ubuntu Natty. Here is a step-by-step walk trough of what worked for me:
  1. change to root or use sudo
  2. apt-get build-dep mediatomb
  3. apt-get source mediatomb
  4. vim mediatomb-0.12.1/debian/rules
  5. change --disable-libjs to --enable-libjs
  6. Now you should update the changelog file in the same directory
  7. get libmozjs2d and libmozjs-dev from the debian sid distibution: libmozjs2d_1.9.1.16-6_i386.deb and libmozjs-dev_1.9.1.16-6_i386.deb
  8. Now you can cd to mediatomb-0.12.1 and try a ./configure. You should see a line in the configuration summary that reads
    libjs                 : yes
  9. Now its time to install additional libs you might what to have for the build. Check the configuration summary. When you are done let's go!
  10. If you are not already there: cd mediatomb-0.12.1
  11. dpkg-buildpackage -rfakeroot -us -uc
That's it! If all went well you should now have three new .deb files in the directory you did the apt-get in. You can install them all in one go by dpkg -i mediatomb*.deb

My thanks go to Gabriel Burca for his solution for Ubuntu 10.04 that was the basis for my Natty solution.

Triggered by Viv's comment, I tried this also on a 64-bit Ubuntu 11.04 (amd64). 
The only difference is in step 7. Here you will have to use the amd64 libraries: libmozjs2d_1.9.1.16-6_amd64.deb and libmozjs-dev_1.9.1.16-6_amd64.deb
After  that there is one additional step:
7.1. apt-get install libjs-prototype

First entry!

Ok, I finally decided to start a blog.  I was looking quite some time for a way to take notes that might also be interesting for others, and have them accessible on the go. So, thanks to my friend Albrecht Schmidt I will try with a blog to keep my public notes and thoughts on computing, computer science and related topics.
