The Gcr package contains libraries used for displaying certificates and accessing key stores. It also provides the viewer for crypto files on the GNOME Desktop.

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.

First, apply a fix for building without OpenSSH installed:
sed '/ssh.add/d; /ssh.agent/d' -i meson.build
Install Gcr by running the following commands:
sed -i 's:"/desktop:"/org:' schema/*.xml &&
mkdir build &&
cd build &&
meson setup --prefix=/usr \
--buildtype=release \
-D gtk_doc=false \
-D ssh_agent=false \
.. &&
ninja
If you have Gi-DocGen-2025.4 installed and wish to build the API documentation for this package, issue:
sed -e "/install_dir/s@,\$@ / 'gcr-3.41.2'&@" \
-i ../docs/*/meson.build &&
meson configure -D gtk_doc=true &&
ninja
To test the results, issue: ninja test. The tests must be run from an X Terminal or similar.
Now, as the root user:
ninja install
--buildtype=release:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-D ssh_agent=false: Disable
the ssh-agent implementation from this package. This implementation
is intended to replace the ssh-agent implementation of gnome-keyring-48.0, but the replacement
still has several unresolved issues.
-D gtk=false: Use this switch if you
haven't installed GTK-3.24.50. Note that gcr-viewer will not be installed if this is
option is used.
-D gtk_doc=true: Allow building this
package without Gi-DocGen-2025.4 installed. If you have
Gi-DocGen-2025.4 installed and you
wish to rebuild and install the API documentation, a meson configure command will
reset this option.
