Colord-1.4.6
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 11.3
platform.

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
Fix a double free causing a build failure on 32-bit x86 and runtime
crashes with some monitors:
sed '/cmsUnregisterPluginsTHR/d' -i lib/colord/cd-context-lcms.c
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
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.
-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-0.56.4 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.
