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

If you have Doxygen-1.9.2 and GTK-Doc-1.33.2 installed and wish to build the API documentation, 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-3.0.10/html &&
cp -vr apidocs/html/* /usr/share/doc/libical-3.0.10/html
