- [gtk-fortran](https://github.com/vmagnin/gtk-fortran/wiki) 4.2.1 offers interfaces to GTK 4.6.2 and GLib 2.72.1. You can of course use it with lower GTK 4 versions, provided that you don’t call new functions. It was tested on Linux, MSYS2/Windows 10, macOS and FreeBSD.

- Thanks to @awvwgk, it can now be installed via [conda](https://github.com/conda-forge/gtk-4-fortran-feedstock) (Linux and macOS only):

```fortran
$ conda install gtk-4-fortran

```

- Last but not the least, gtk-fortran can now be used as a [fpm](https://fpm.fortran-lang.org) dependency (gtk4 branch only), as explained in the tutorial 5 [“How to use fpm to build a gtk-fortran project”](https://github.com/vmagnin/gtk-fortran/wiki/Tutorial-5), based on the [gtkzero\_fpm example](https://github.com/vmagnin/gtkzero_fpm). Supposing you have already installed fpm and the GTK 4 development files (`libgtk-4-dev` package in Ubuntu), building and running that example should be as simple as typing:

```bash
$ git clone git@github.com:vmagnin/gtkzero_fpm.git
$ cd gtkzero_fpm
$ fpm run

```

A “Hello World” GTK empty window should appear on screen:

It’s very simple to use, the key lines in the `fpm.toml` manifest of that example being just:

```nohighlight
[dependencies]
gtk-fortran = { git = "https://github.com/vmagnin/gtk-fortran.git", branch = "gtk4" }

```

Note that if you have several projects using gtk-fortran, it would be a better solution to clone the gtk-fortran repository alongside your projects and replace in their `fpm.toml` manifests the git dependency by the local path to gtk-fortran:

```nohighlight
[dependencies]
gtk-fortran = { path = "../gtk-fortran" }

```

Have fun! You can post issues here or on [GitHub](https://github.com/vmagnin/gtk-fortran/issues). But you can also post success 😉

Another gtk-fortran example, in the [gtk-fortran-extra](https://github.com/vmagnin/gtk-fortran-extra) repository, has become a fpm project using gtk-fortran as a dependency:

```bash
$ git clone git@github.com:vmagnin/gtk-fortran-extra.git
$ cd gtk-fortran-extra/unknown_pleasures
$ fpm run

```

It uses the [Cairo](https://www.cairographics.org/) vectorial drawing library, which is part of GTK.
