Installation

Linux

For Linux you need Wayland and the wayland, x11, xkbcommon, GLES, EGL, libXcursor development packages.

On Fedora 28 and newer, install the dependencies with the command

$ dnf install gcc pkg-config wayland-devel libX11-devel libxkbcommon-x11-devel mesa-libGLES-devel mesa-libEGL-devel libXcursor-devel

On Ubuntu 18.04 and newer, use

$ apt install gcc pkg-config libwayland-dev libx11-dev libx11-xcb-dev libxkbcommon-x11-dev libgles2-mesa-dev libegl1-mesa-dev libffi-dev libxcursor-dev

You can build Gio programs without X11 support with the nox11 build tag, and without Wayland support with the nowayland build tag.

macOS, iOS, tvOS

Xcode is required for Apple platforms.

Windows

To avoid the console appearing when running Gio programs, use the -H windowsgui linker flag:

$ go build -ldflags="-H windowsgui" gioui.org/example/hello

Android

For Android you need the Android SDK with the NDK bundle installed.

Point the ANDROID_HOME to the SDK root directory. To install the NDK bundle use the sdkmanager command that comes with the SDK:

$ sdkmanager ndk-bundle

To run Gio programs on the emulator, you may need to enable OpenGL ES 3.

Webassembly/WebGL

To run Gio in a browser you need support for WebAssembly and WebGL.

Building for webassembly requires Go 1.14.
