Installation of Colord

[Warning]

Warning

This package will overwrite any previous version of Colord that you may have on your system. This package is a development version and is only intended to be used by gnome-color-manager at this time.

There should be a dedicated user and group to take control of the colord daemon after it has 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-daemon            \
            --enable-session-helper    \
            --enable-libcolordcompat   \
            --disable-rpath            \
            --disable-argyllcms-sensor \
            --disable-bash-completion  \
            --disable-static &&
make

Now, as the root user: 

make install

To test the results, issue: make -k check. At least one test, ./lib/colord/.libs/lt-cd-test-daemon, may fail. The test suite must be run after the package is installed, and the system-wide D-Bus Daemon must be running.

Command Explanations

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

--enable-vala: This switch enables building the Vala bindings. Remove if you don't have Vala-0.34.4 installed.

--enable-daemon: This switch enables building the Colord daemon.

--enable-session-helper: This switch enables building the session helper for Colord.

--enable-libcolordcompat: This switch enables building a compatibility library for older packages that use Colord.

--disable-rpath: This switch prevents the build process from hard-coding library paths into its executables.

--disable-argyllcms-sensor: This switch disables the ArgLLCMS sensor driver. Omit if you have ArgLLCMS installed and wish to use it.

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

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

--enable-gtk-doc: Use this parameter if GTK-Doc is installed and you wish to rebuild 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 libgudev installed.

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