Installation of Gcr



If you are upgrading from a version of gcr prior to 3.36.0, you must run the remove-la-files.sh script from the Libtool archive (.la) files after installing gcr.

Install Gcr by running the following commands:

sed -i 's:"/desktop:"/org:' schema/*.xml &&

mkdir gcr-build &&
cd    gcr-build &&

meson --prefix=/usr -Dgtk_doc=false .. &&

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

Command Explanations

sed ... schema/*.xml: This command fixes a deprecated entry in the schema template.

-Dgtk=false: Use this switch if you haven't installed GTK+-3.24.25. Note that gcr-viewer will not be installed if this is passed to meson.

-Dgtk_doc=true: Use this switch if you wish to generate the API reference documentation. Note that you must have GTK-Doc installed.
