CI

This python script helps you build a full GTK library stack for Windows using Visual Studio. Currently, GTK 3 and GTK 4 are supported.

Install GTK Only

If you want to only run GTK on Windows and not build it yourself, you can download a zip file from the latest release and unzip it to C:\gtk.

It comes with GTK4, Cairo, PyGObject, Pycairo, GtkSourceView5, adwaita-icon-theme, and all of their dependencies.

Note however that these binaries are provided “AS IS”, WITHOUT WARRANTY OF ANY KIND. They just contain the output of our latest CI run. They are not tested, and we cannot commit to timely updates even for security issues. We strongly recommend to build your own binaries, especially if you plan to distribute them with your application or use them in production.

Environmental Variables

Finally, add GTK to your environmental variables with:

$env:Path = "C:\gtk\bin;" + $env:Path
$env:LIB = "C:\gtk\lib;" + $env:LIB
$env:INCLUDE = "C:\gtk\include;C:\gtk\include\cairo;C:\gtk\include\glib-2.0;C:\gtk\include\gobject-introspection-1.0;C:\gtk\lib\glib-2.0\include;" + $env:INCLUDE

PyGObject and PyCairo

If you are going to use PyGObject and Pycairo, you also need to use the gvsbuild generated wheels with your Python virtualenv in order to work around this PyGObject bug:

pip install --force-reinstall (Resolve-Path C:\gtk\wheels\PyGObject*.whl)
pip install --force-reinstall (Resolve-Path C:\gtk\wheels\pycairo*.whl)

Build GTK

The script supports multiple versions of Visual Studio - at the moment we are focusing on VS 2022, but we include projects for other versions, and we gladly accept patches.

The script focuses on GTK and the surrounding ecosystem (e.g. GStreamer). However, we are open to adding more libraries as long as the contributor takes on the responsibility for keeping it up to date. The supported projects are modules in the projects directory.

The script requires a working installation of Visual Studio for Windows Desktop, Python 3 and msys2. The script will download any additional tools required to build the libraries and will use them from a local directory, without any installation. As of today these tools include cmake, meson, ninja, nuget and perl.

The script fetches source tarballs for the projects from their original locations, however in some cases it might be necessary to host a patched tarball on GitHub. To ensure integrity of the downloaded files, the script checks the SHA256 hash of each download. Downloads are done using TLS, using SSL certificates provided by the system, but in case of error the download is tried again ignoring certificate errors.

First we need to install the prerequisites. There are two main options:

  1. WinGet - Available for Windows 11, and modern versions of Windows 10
  2. Chocolately - An alternative for other Windows versions

Prerequisites with WinGet

If you would prefer to use Chocolately instead of WinGet, you can skip this section and follow the Prerequisites with Chocolately steps.

WinGet

WinGet is the Windows Package Manager and is available on Windows 11 and modern versions of Windows 10 (1809 / build 17763) as a part of the App Installer package in the Windows Store.

Git

To setup a development environment in Windows install Git by executing as an administrator:

winget install --id Git.Git -e --source winget

MSYS2

Both of the development environments in the next steps need MSYS2 installed.

Install MSYS2:

Keep PowerShell open as administrator and execute:

winget install --id MSYS2.MSYS2 -e --source winget

Install Visual Studio 2022

With your admin PowerShell terminal:

winget install Microsoft.VisualStudio.2022.BuildTools -e --source winget --silent --override "--wait --quiet --add ProductLang En-us --add Microsoft.VisualStudio.Workload.VCTools --includeRecommended"

Restart your computer following this installation.

Note: Visual Studio versions 2013 (not for all projects), 2015, 2017, 2019, and 2022 are currently supported.

Install the Latest Python

With your admin PowerShell terminal:

winget install --id Python.Python.3.13 -e --source winget
  1. Open a PowerShell terminal as a normal user and check the python version:

    py -3.13 --version

Prerequisites with Chocolately

If you already installed the prerequisites with WinGet, you can skip this section.

Chocolatey

An alternative to WinGet is using Chocolately as a package manager in Windows.

To install it, open PowerShell as an administrator, then execute:

Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

To run local scripts in follow-on steps, also execute Set-ExecutionPolicy RemoteSigned. This allows for local PowerShell scripts to run without signing, but still requires signing for remote scripts.

Git

To setup a development environment in Windows install Git by executing as an administrator:

choco install git

MSYS2

Both of the development environments in the next steps need MSYS2 installed.

Install MSYS2:

Keep PowerShell open as administrator and execute:

choco install msys2

Install Visual Studio 2022

With your admin PowerShell terminal:

choco install visualstudio2022-workload-vctools

Note: Visual Studio versions 2013 (not for all projects), 2015, 2017, 2019, and 2022 are currently supported.

Install the Latest Python

With your admin PowerShell terminal:

choco install python312
  1. Open a PowerShell terminal as a normal user and check the python version:

    py -3.13 --version

Install gvsbuild

The recommended way to install gvsbuild is with pipx. Open a new regular user PowerShell terminal and execute:

py -3.13 -m pip install --user pipx
py -3.13 -m pipx ensurepath
pipx install gvsbuild

Alternatively, you can also use git to clone the repository and install it. Open a new regular user PowerShell terminal and execute:

mkdir C:\gtk-build\github
cd C:\gtk-build\github
git clone https://github.com/wingtk/gvsbuild.git
cd C:\gtk-build\github\gvsbuild
python -m venv .venv
.\.venv\Scripts\activate.ps1
pip install .

Build GTK

In the same PowerShell terminal, execute:

gvsbuild build gtk3

Alternatively, if you want to build GTK 4, execute:

gvsbuild build gtk4

Grab a coffee, the build will take a few minutes to complete.

Add GTK to Your Environmental Variables

  1. From the Start menu, go to the Control Panel entry for “Edit environment variables for your account”.
  2. Double-click the Path row in the top list of variables. Click “New” to add a new item to the list.
  3. Paste in C:\gtk-build\gtk\x64\release\bin
  4. Click "OK" twice.

You are now ready to use GTK!

Additional Gvsbuild Usage

Using GTK with Visual Studio

  1. Open Visual Studio and "Create a new project" using the "Empty Project" template

  2. On the left, right click on "Source Files" and choose "Add", then "New Item..." and replace the name with main.c

  3. Paste in the following contents, then save the file:

    #include <gtk/gtk.h>
    
    static void activate_cb(GtkApplication *app) {
     GtkWidget *window = gtk_application_window_new(app);
     gtk_widget_set_visible(window, true);
    }
    
    int main(int argc, char **argv) {
     GtkApplication *app =
         gtk_application_new("org.app", G_APPLICATION_DEFAULT_FLAGS);
     g_signal_connect(app, "activate", G_CALLBACK(activate_cb), NULL);
     return g_application_run(G_APPLICATION(app), argc, argv);
    }
  4. Go to your project's settings by right-clicking and choosing "Properties"

    screenshot showing the properties item is at the bottom of the context menu

  5. On the left, open "C/C++", then choose "Command Line".

    1. Open "Powershell" and run the command pkg-config --cflags gtk4 --msvc-syntax
    2. Paste the result into the "Additional Options" field at the bottom of the Visual Studio Properties window.

  6. Still in the Visual Studio window, click on "Linker" and choose "Command Line". Do the same thing as the last step, except use the output of pkg-config --libs gtk4 --msvc-syntax

  7. Click "OK"

  8. In the top menu bar, click "Debug" and "Start Without Debugging"

Using GTK with Rust

See the fantastic gtk-rs book. You can skip the "Install GTK 4" step, as the above steps ^ covered that.

Use PyGObject

First, add GTK to your environment variables:

$env:LIB = "C:\gtk-build\gtk\x64\release\lib;" + $env:LIB
$env:INCLUDE = "C:\gtk-build\gtk\x64\release\include;C:\gtk-build\gtk\x64\release\include\cairo;C:\gtk-build\gtk\x64\release\include\glib-2.0;C:\gtk-build\gtk\x64\release\include\gobject-introspection-1.0;C:\gtk-build\gtk\x64\release\lib\glib-2.0\include;" + $env:INCLUDE

Next, add the --enable-gi and --py-wheel options like:

gvsbuild build --enable-gi --py-wheel gtk4 pygobject

Once that finishes, then you need to use the gvsbuild generated wheels with your Python virtualenv in order to work around this PyGObject bug:

pip install --force-reinstall (Resolve-Path C:\gtk-build\build\x64\release\pygobject\dist\PyGObject*.whl)
pip install --force-reinstall (Resolve-Path C:\gtk-build\build\x64\release\pycairo\dist\pycairo*.whl)

Use Icons with GTK

If you are going to use SVG icons with a GTK app, you need to also need to build librsvg. Normally you want to build GTK with gvsbuild build gtk4 adwaita-icon-theme which will include librsvg and hicolor-icon-theme.

Other Options

For more information about the possible commands run:

 gvsbuild --help

To get detailed help on the build command run:

 gvsbuild build --help

It is possible to set some parameters from a file, e.g. vs2015-release.pro, putting the @ character before the file name. The file contains the option, one per line, separated by a carriage return:

 --vs-ver
 14
 --win-sdk
 8.1
 --configuration
 release

Even if the format is not the easier to write or read in this way we eliminate the problem of escaping spaces is file names and directories. Then you can use it:

 gvsbuild build @vs2015-release.pro gtk3-full

Troubleshooting

OpenSSL

In addition to the setup instructions above, to build OpenSSL you also need the Visual C++ 2013 Redistributable Package installed. To install it, open PowerShell as administrator and execute:

choco install vcredist2013

Similar to other packages, you can build OpenSSL by executing:

gvsbuild build openssl

Dependency Graph

To see and analyze the dependency between the various projects, in text or in a Graphviz format, use the script deps.py:

gvsbuild deps --graph --gv-file test.gv

Without option a simple dependency of all the projects is printed, as usual with --help a summary of the options/commands is printed.

Credits

This tool originated from a gtk-win32 PowerShell script created by the HexChat developers for building it for Windows. Although this project is now archived, you can explore the original project if you are interested in the history at https://github.com/hexchat/gtk-win32.

Compiling the GTK stack on MSVC would not be possible without the incredible work by Fan Chun-wei. If you are interested in more details of how this works, please see Compiling the GTK+ (and Clutter) stack using Visual C++ 2008 and later.
