- Download size: 1.2 MB

- Estimated disk space required: 15 MB (with tests)

- Estimated build time: 0.1 SBU (with tests)

### JSON-GLib Dependencies

#### Required

GLib-2.88.0 (GObject Introspection required if building GNOME)

#### Optional

docutils-0.22.4 and Gi-DocGen-2026.1

## Installation of JSON GLib

Install JSON GLib by running the following commands:

    mkdir build &&
    cd    build &&

    meson setup --prefix=/usr --buildtype=release .. &&
    ninja

If docutils-0.22.4 is installed, build the man pages:

    meson configure -D man=true &&
    ninja

If Gi-DocGen-2026.1 is installed, build the API documentation:

    sed "/json_docdir =/s|$| / 'json-glib-1.10.8'|" -i ../doc/meson.build &&
    meson configure -D documentation=enabled &&
    ninja

To test the results, issue: ninja test. One test, node, is known to fail.

Now, as the `root` user:

    ninja install

## Command Explanations

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

`-D gtk_doc=disabled`: Add this option if you have GTK-Doc-1.36.1 installed and do not wish to generate the API documentation.
