Installation of Avahi

There should be a dedicated user and group to take control of the avahi-daemon daemon after it is started. Issue the following commands as the root user: 

groupadd -fg 84 avahi &&
useradd -c "Avahi Daemon Owner" -d /var/run/avahi-daemon -u 84 \
        -g avahi -s /bin/false avahi

There should also be a dedicated priviliged access group for Avahi clients. Issue the following command as the root user: 

groupadd -fg 86 netdev

Install Avahi by running the following commands: 

./configure --prefix=/usr        \
            --sysconfdir=/etc    \
            --localstatedir=/var \
            --disable-static     \
            --disable-mono       \
            --disable-monodoc    \
            --disable-python     \
            --disable-qt3        \
            --disable-qt4        \
            --enable-core-docs   \
            --with-distro=none   \
            --with-systemdsystemunitdir=/lib/systemd/system &&
make

This package does not come with a test suite.

Now, as the root user: 

make install

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.

--disable-mono: This parameter disables the Mono bindings.

--disable-monodoc: This parameter disables documentation for the Mono bindings.

--disable-python: This parameter disables the scripts that depend on Python. It also allows a regular install to complete successfully.

--disable-qt3: This parameter disables the attempt to build the obsolete Qt3 portions of the package.

--disable-qt4: This parameter disables the attempt to build the obsolete Qt4Core portions of the package.

--enable-core-docs: This parameter enables the building of documentation.

--with-distro=none: There is an obsolete boot script in the distribution for LFS. This option disables it.

--with-systemdsystemunitdir=/lib/systemd/system: This parameter is used to set the correct installation directory for systemd units.

--disable-dbus: This parameter disables the use of D-Bus.

--disable-gtk: This parameter disables the use of GTK+2.

--disable-gtk3: This parameter disables the use of GTK+3.

--disable-libdaemon: This parameter disables the use of libdaemon. If you use this option, avahi-daemon won't be built.

--enable-tests: This option enables the building of tests and examples.

--enable-compat-howl: This option enables the compatibility layer for HOWL.

--enable-compat-libdns_sd: This option enables the compatibility layer for libdns_sd.
