After getting really annoyed with all the directories piling up in my /usr/local/xen directory, Benv offered to try and find out why the hell these directories didn’t want to get deleted.
It seemed that the directories had a flag ’schg’ which you can see by doing an ‘ls -lo’ on the directory. The ’schg’ flag means that the directory is system immutable and only the owner and superuser are allowed to remove this flag.
This is done by calling chflags 0 on the directory. This clears all it’s flags.

I fixed my problem by doing:

But when it tried to run configure, there was nothing to configure so I figured it was smart to quit the slackbuild script and check it out myself.
It seems that there was indeed no configure file, but the INSTALL file told me I had to run “make linux install” to build and install the library for my platform. Well that’s nice, but where will it install everything? Benv hinted me that I should probably edit the Makefile and change INSTALL_TOP to INSTALL_TOP= /usr/src/lua-5.1.4/pkg/usr so I could run makepkg after to create my own package. But after creating and installing the lua package, edje still complained that there was no liblua installed on my machine.
Checking my config.log I found out it was searching for liblua in the pkgconfig files. Oddly enough, the lua src did have a etc/lua.pc file, but it does not install it. So I placed it in /usr/src/lua-5.1.4/pkg/usr/share/pkgconfig/ directory and I changed the paths so it would match my installation and I recreated and reinstalled the package.
This time edje did find the library, but crashed with the following error:

After googling a little and checking the error again, I found out that the Makefile needed to be patched so it would also use the -fPIC option. So I edited the /usr/src/lua-5.1.4/src/Makefile and changed

to

, ran the make linux install, created a new package, installed the package and it finally worked \o/

If you wonder what picard is, you can check it out here: PicardTagger

To install Picard, you’ll need the following software

• fftw3
• libofa (0.9.2 or later)
• Libmusicbrainz 2
• mutagen
• ffmpeg
• Picard

Building fftw3

When you build fftw3, make sure you run configure with –enable-shared since it’s default set to ‘no’.

Building libofa

Building libofa is not as trivial as it seems. Since it’s quite old, it’ll need some patches. What I did, was downloading the libofa src from ubuntu and use the ubuntu patches to make it compile.

Building libmusicbrainz

For libmusicbrainz you’ll have to patch some files as well. A nice overview of files that need to be patched can be found here

You’ll also have to install the python library which you can find in the package it self in the python directory. Just run ./setup.py config ./setup.py build and ./setup.py install.

Building mutagen

I downloaded the latest version from mutagen from the google code project site

Just unpack it and run ./setup.py install to install the package

Building ffmpeg

When you build ffmpeg, make sure you run configure with –enable-shared since it’s default set to ‘no’.

Installing Picard

Now you’ve finally installed all the dependencies, you can install Picard. In my case I’m installing Picard 0.11 which expect an older ffmpeg install so it needs to be patched as well to be able to find the avcodec.h and avformat.h files. Edit the setup.py file and search for  cfg.set(’avcodec’, ‘cflags’, cfg.get(’avcodec’, ‘cflags’) + ‘ -DUSE_OLD_FFMPEG_LOCATIONS’). You’ll have to replace it with fg.set(’avcodec’, ‘cflags’, cfg.get(’avcodec’, ‘cflags’)) and all should be working.
