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.
Note
Development versions of BLFS may not build or run some packages
properly if LFS or dependencies have been updated since the most
recent stable versions of the books.

Colord Dependencies
Required
dbus-1.14.10, GLib-2.82.1 (GObject Introspection
recommended), Little CMS-2.16, Polkit-125, and
SQLite-3.46.1
Recommended
elogind-255.5, libgudev-238, libgusb-0.4.9,
and Vala-0.56.17
Optional
gnome-desktop-44.1 and colord-gtk-0.3.1 (to build the example
tools), DocBook-utils-0.6.14, GTK-Doc-1.34.0,
libxslt-1.1.42, SANE-1.2.1, ArgyllCMS, and
Bash Completion
Installation of Colord
First, fix a misuse of the sqlite API causing a test failure and
potential runtime crash:
patch -Np1 -i ../colord-1.4.7-upstream_fixes-1.patch
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:
mkdir build &&
cd build &&
meson setup .. \
--prefix=/usr \
--buildtype=release \
-D daemon_user=colord \
-D vapi=true \
-D systemd=false \
-D libcolordcompat=true \
-D argyllcms_sensor=false \
-D bash_completion=false \
-D docs=false \
-D man=false &&
ninja
Now, as the root
user:
ninja install
To test the results, issue: ninja
test. One test, colord-self-test-daemon
, will fail if the package
is already installed. The test suite must be run with the
system-wide D-Bus Daemon running.
Command Explanations
--buildtype=release
:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-D daemon_user=colord
: This
switch is used so the colord daemon will run as an unprivileged
user instead of the root
user.
-D vapi=true
: This switch
enables building the Vala
bindings. Remove if you don't have Vala-0.56.17 installed.
-D systemd=false
: This
switch disables support for systemd login in Colord applications.
-D libcolordcompat=true
:
This switch enables building a compatibility library for older
packages that use Colord.
-D argyllcms_sensor=false
:
This switch disables the ArgLLCMS sensor driver. Omit if you have
ArgyllCMS
installed and wish to use it.
-D bash_completion=false
:
This switch disables Bash Completion support for Colord
applications.
-D docs=false
: This switch
disables building of documentation. Omit if you have GTK-Doc-1.34.0 available.
-D man=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.
