A Swift wrapper around clutter that is largely auto-generated from gobject-introspection
To build, you need at least Swift 4.2 (Swift 5.x should work fine), download from https://swift.org/download/ -- if you are using macOS, make sure you have the command line tools installed as well). Test that your compiler works using
swift --version, which should give you something like
$ swift --version Apple Swift version 5.2.4 (swiftlang-118.104.22.168 clang-122.214.171.124) Target: x86_64-apple-darwin19.4.0
on macOS, or on Linux you should get something like:
$ swift --version Swift version 5.2.4 (swift-5.2.4-RELEASE) Target: x86_64-unknown-linux-gnu
GLib 2.46 or higher
These Swift wrappers have been tested with glib-2.46, 2.48, 2.52, 2.56, 2.58, 2.60, 2.62, and 2.64. They should work with higher versions, but YMMV. Also make sure you have
gobject-introspection and its
.gir files installed.
On Ubuntu 18.04 and 16.04 you can use the gtk that comes with the distribution. Just install with the
apt package manager:
sudo apt update sudo apt install libclutter-1.0-dev gir1.2-clutter-1.0 gobject-introspection libgirepository1.0-dev libxml2-dev
If you prefer a newer version of gtk, you can also install it from the GNOME 3 Staging PPA (see https://launchpad.net/~gnome3-team/+archive/ubuntu/gnome3-staging), but be aware that this can be a bit dangerous (as this removes packages that can be vital, particularly if you use a GNOME-based desktop), so only do this if you know what you are doing:
sudo add-apt-repository ppa:gnome3-team/gnome3-staging sudo apt update sudo apt dist-upgrade sudo apt install libclutter-1.0-dev gir1.2-clutter-1.0 gobject-introspection libgirepository1.0-dev libxml2-dev
On Fedora 29, you can use the gtk that comes with the distribution. Just install with the
dnf package manager:
sudo dnf install clutter-devel cogl-devel pango-devel cairo-devel cairo-gobject-devel glib2-devel gobject-introspection-devel libxml2-devel
On macOS, you can install glib and Clutter using HomeBrew (for setup instructions, see http://brew.sh). Once you have a running HomeBrew installation, you can use it to install a native version of Clutter:
brew update brew install clutter glib glib-networking gobject-introspection pkg-config
Normally, you don't build this package directly, but you embed it into your own project (see 'Embedding' below). However, you can build and test this module separately to ensure that everything works. Make sure you have all the prerequisites installed (see above). After that, you can simply clone this repository and build the command line executable (be patient, this will download all the required dependencies and take a while to compile) using
git clone https://github.com/rhx/SwiftClutter.git cd SwiftClutter ./build.sh ./test.sh
On macOS, you can build the project using Xcode instead. To do this, you need to create an Xcode project first, then open the project in the Xcode IDE:
./xcodegen.sh open Clutter.xcodeproj
After that, use the (usual) Build and Test buttons to build/test this package.
Here are some common errors you might encounter and how to fix them.
Old Swift toolchain or Xcode
If you get an error such as
$ ./build.sh error: unable to invoke subcommand: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/swift-package (No such file or directory)
this probably means that your Swift toolchain is too old. Make sure the latest toolchain is the one that is found when you run the Swift compiler (see above).
If you get an older version, make sure that the right version of the swift compiler is found first in your
PATH. On macOS, use xcode-select to select and install the latest version, e.g.:
sudo xcode-select -s /Applications/Xcode.app xcode-select --install
