User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/colord

Installation of Colord

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

groupadd -g 71 colord &&
useradd -c "Color Daemon Owner" -d /var/lib/colord -u 71 \
        -g colord -s /bin/false colord

Install Colord by running the following commands: 

./configure --prefix=/usr                \
            --sysconfdir=/etc            \
            --localstatedir=/var         \
            --with-daemon-user=colord    \
            --enable-vala                \
            --enable-systemd-login=no    \
            --disable-argyllcms-sensor   \
            --disable-bash-completion    \
            --disable-static             \
            --with-systemdsystemunitdir=no &&
make

Now, as the root user: 

make install

To test the results, issue: make -k check. For unknown reasons, some tests may fail. Note that the system-wide D-Bus daemon must be running or the tests will fail.

Command Explanations

--with-daemon-user=colord: This switch is used so the colord daemon will run as an unprivileged user instead of root user.

--enable-vala: This switch enables building of the Vala bindings. Remove if you don't have Vala-0.28.1 installed.

--enable-systemd-login=no: This parameter fixes building without systemd, which is not part of LFS/BLFS. If you use systemd, replace "no" by "yes".

--disable-argyllcms-sensor: Disables ArgllCMS sensor driver.

--disable-bash-completion: This switch disables Bash Completion support for Colord apps.

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

--with-systemdsystemunitdir=no: Disables attempting to build with systemd libraries.

--enable-gtk-doc: Use this switch if GTK-Doc is installed and you wish to build and install the API documentation.

--disable-gusb: Use this switch if you don't have libgusb installed.

--disable-udev: Use this switch if you don't have GUdev installed.

--disable-polkit: Use this switch if you don't have Polkit installed.
