Installation of libical

Install libical by running the following commands:

[Note]

Note

This package may occasionally fail when building with multiple processors. See Using Multiple Processors for more information.

mkdir build &&
cd    build &&

cmake -DCMAKE_INSTALL_PREFIX=/usr  \
      -DCMAKE_BUILD_TYPE=Release   \
      -DSHARED_ONLY=yes            \
      -DICAL_BUILD_DOCS=false      \
      -DGOBJECT_INTROSPECTION=true \
      -DICAL_GLIB_VAPI=true        \
      .. &&
make -j1

If you have Doxygen-1.9.6, Graphviz-7.1.0, and GTK-Doc-1.33.2 installed and wish to build the API documentation, you should remove the -DICAL_BUILD_DOCS=false switch and issue: 

make docs

To test the results, issue: make test.

Now, as the root user: 

make install

If you have built the API documentation, install by issuing, as root user: 

install -vdm755 /usr/share/doc/libical-3.0.16/html &&
cp -vr apidocs/html/* /usr/share/doc/libical-3.0.16/html

Command Explanations

-DCMAKE_BUILD_TYPE=Release: This switch is used to apply higher level of the compiler optimizations.

-DSHARED_ONLY=yes: This switch is used in order to only build the shared libraries.

-DICAL_BUILD_DOCS=false: This switch prevents building the GTK documentation. Remove if you want to build the documentation.

-DGOBJECT_INTROSPECTION=true: This switch is used to generate GObject metadata bindings.

-DICAL_GLIB_VAPI=true: This switch is used in order to build bindings for Vala-0.56.4.

-DUSE_BUILTIN_TZDATA=yes: This switch is used in order to build using your own timezone data.
