==Introduction==
OK... so I was looking for things to do with the [[Lemote Fulong | Fulong]], so I headed over to [http://freshmeat.net Freshmeat] and found something that interested me, namely a program called [[Clive]].
==Building==
Well, reading up on this thing a bit more, it turns out that one of the options for it is to push the files through ffmpeg and urlgrabber in order to reencode them. urlgrabber is just a python script, so no big deal there, but I needed ffmpeg.

It turns out that ffmpeg is only available via svn (i.e. Subversion), and of course the Fulong doesn't have THAT installed. So now I have to install Subversion. Welcome to dependency hell. Subversion in turn requires apr and apr-util, both of which are parts of the Apache Portable Runtime. So I go and grab those. apr compiles and installs without problem with a simple configure and make. apr-util required a bit more finesse on the configure line because it depended on apr:
<pre>
./configure --with-apr=/home/src/apr-1.2.12
</pre>
OK, so we have the dependencies of subversion down. Now to build subversion. Of course, a bit more finessing on the configure line is involved here:
<pre>
./configure --with-apr=/home/src/apr-1.2.12 --with-apr-util=/home/src/apr-util-1.2.12
</pre>

-No problems, and subversion worked like a charm! Now to actually compile ffmpeg. Unfortunately, it breaks when it gets to doing a framehook against imlib2. Go figure, seeing as the build for THAT software was a bit sketchy itself because of a slightly munged dependency:

 Well, that built, so now I was able to grab the subversion version of ffmpeg:
