Colord-1.4.5

Introduction to Colord

Colord is a system service that makes it easy to manage, install, and generate color profiles. It is used mainly by GNOME Color Manager for system integration and use when no users are logged in.

This package is known to build and work properly using an LFS-10.1 platform.

User Notes: https://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 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

First, clean up about 100 warnings:

mv po/fur.po po/ur.po &&
sed -i 's/fur/ur/' po/LINGUAS

Install Colord by running the following commands:

mkdir build &&
cd build &&

meson --prefix=/usr            \
      --buildtype=release      \
      -Ddaemon_user=colord     \
      -Dvapi=true              \
      -Dsystemd=true           \
      -Dlibcolordcompat=true   \
      -Dargyllcms_sensor=false \
      -Dbash_completion=false  \
      -Ddocs=false             \
      -Dman=false ..           &&
ninja

Now, as the root user:

ninja install

To test the results, issue: ninja -k 2 test. One test, colord-self-test-daemon, will fail. The test suite must be run after the package is installed, and the system-wide D-Bus Daemon must be running.

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

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

-Dvapi=true: This switch enables building the Vala bindings. Remove if you don't have Vala-0.52.4 installed.

-Dsystemd=true: This switch enables installation of the systemd service.

-Dlibcolordcompat=true: This switch enables building a compatibility library for older packages that use Colord.

-Dargyllcms_sensor=false: This switch disables the ArgLLCMS sensor driver. Omit if you have ArgyllCMS installed and wish to use it.

-Dbash_completion=false: This switch disables Bash Completion support for Colord applications.

-Ddocs=false: This switch disables building of documentation. Omit if you have GTK-Doc-1.33.2 available.

-Dman=false: This switch disables building of man pages. Omit if you have DocBook-utils-0.6.14 available. Namespaced versions of the docbook-xsl stylesheets are also required.
