Schemas are compiled into binary form by the

GIO provides a <literal>glib_compile_schemas</literal>
variable for the schema compiler, which can be used in

You can ignore all of this by using the provided m4 macros. To
do this, add to your <filename>configure.ac</filename>:
<programlisting>
GLIB_GSETTINGS
</programlisting>
The corresponding <filename>Makefile.am</filename> fragment looks like
this:
<programlisting>
# gsettingsschemadir and gschema_compile are defined by the GLIB_GSETTINGS
# macro in configure.ac
gsettingsschema_DATA = my.app.gschema.xml
# This rule will check your schemas for validity before installation

$(GLIB_COMPILE_SCHEMAS) $(DESTDIR)$(gsettingsschemadir)

# gsettings_SCHEMAS is a list of all the schemas you want to install
gsettings_SCHEMAS = my.app.gschema.xml
# include the appropriate makefile rules for schema handling
