If you are building from a Git checkout, you must first generate the configure script using the autotools build system:

# ./autogen.sh

To compile and install, type:

# ./configure
# make
# su root
Password: <root password>
# make install

You need to do this in ddccontrol and ddccontrol-db directories.

If you set the --prefix parameter when configuring one package, you must set it to the same value when configuring the other.
