Package Information

GObject Introspection Dependencies

Required

GLib-2.78.3

Optional

Cairo-1.18.0 (required for the tests), Gjs-1.78.3 (to satisfy one test), GTK-Doc-1.33.2, Mako-1.3.0, and Markdown-3.4.1

Installation of GObject Introspection

Install GObject Introspection by running the following commands: 

mkdir build &&
cd    build &&

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

To test the results, fix an incompatibility of the test suite with Python 3.12 or later and then run the test suite: 

sed "/PYTHONPATH/a'/usr/lib/python3.12'," -i ../tests/warn/meson.build &&
ninja test

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.

-Dgtk_doc=true: Build and install the documentation.
