I'm receiving the following error while trying to 'make' 4.0b1. If you have any suggestions as to how to fix this I would be grateful.

Try this:

sudo apt-get install --reinstall libphonon-dev

Then rerun cmake and make again.

I'm getting the same result as before. I was able to successfully compile 4.0b1 on Ubuntu Karmic. I just upgraded to Lucid and now I'm getting the above error. Not sure if that piece of information is of any use in troubleshooting this.

Then the phonon development package must be broken on lucid.

Some helpful person, jonasl, from the IRC suggested I try this.

cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` -DENABLE_MEDIAPLAYER_PLUGIN=false

That took care of it.

Yes, I still have lots to learn.
