# libnotify-0.8.8

## Introduction to libnotify

The libnotify library is used to send desktop notifications to a notification daemon, as defined in the Desktop Notifications spec. These notifications can be used to inform the user about an event or display some form of information without getting in the user's way.

### Note

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.

## Installation of libnotify

Install libnotify by running the following commands:

    mkdir build &&
    cd    build &&

    meson setup --prefix=/usr       \
                --buildtype=release \
                -D gtk_doc=false    \
                -D man=false        \
                ..                  &&
    ninja

To test the results, you must have the xvfb-run program installed into /usr/bin. If you have xvfb-run, issue: ninja test to run the tests.

If you have Gi-DocGen-2026.1 installed and wish to build the API documentation for this package, issue:

    sed "/docs_dir =/s@\$@ / 'libnotify'@" \
        -i ../docs/reference/meson.build   &&
    meson configure -D gtk_doc=true        &&
    ninja

Now, as the `root` user:

    ninja install &&
    if [ -e /usr/share/doc/libnotify ]; then
      rm -rf /usr/share/doc/libnotify-0.8.8
      mv -v  /usr/share/doc/libnotify{,-0.8.8}
    fi

## Command Explanations

`--buildtype=release`: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

`-D tests=false`: Use this option if you have not installed the recommended dependency GTK-4.22.4.
