1. Requirements

First of all: You need at least gmerlin, which can be downloaded from
the gmerlin website. All other libraries are OPTIONAL, i.e. the configure script
will search for them and use them, if they are found. The more libraries you have,
the more files formats you can encode, e.g. if you really don't want to encode FLAC 
files, you can skip the installation of flac and everything will be fine for you.

If you installed a library but it wasn't found by the configure script,
the error is in 99% of the cases one of the following:

- A binary package (e.g. rpm) was installed but not the development package
 (e.g. for libfoo-1.2.3-4.i386.rpm you also need libfoo-devel-1.2.3-4.i386.rpm)

- The path where the libraries got installed (usually /usr/local/bin for source
  packages) is missing in the file /etc/ld.so.conf. This is the case e.g. on
  Fedora Core 3. Add the path there, run /sbin/ldconfig as root and everything
  should work.

- After installation of the library, /sbin/ldconfig wasn't called

- The package wasn't found, because the environment variable PKG_CONFIG_PATH is not
  properly set. Typing

  export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

  before calling configure helps in most cases.

If all these tips don't help, attach the file config.log to an email and send it to
gmerlin-general@lists.sourceforge.net.

2. Compilation

Nothing special here. It's the usual procedure:

./configure
make
su
<type root password>
make install

The configure script supports some command line options, type

./configure --help

to see them.
