Build instructions for Windows 64-bit

• Prepare folder
• Install third party software
• Clone source code and prepare libraries
• Build the project

Prepare folder

The build is done in Visual Studio 2022 with 10.0.26100.0 SDK version.

Choose an empty folder for the future build, for example D:\TBuild. It will be named BuildPath in the rest of this document. Create two folders there, BuildPath\ThirdParty and BuildPath\Libraries.

All commands (if not stated otherwise) will be launched from x64 Native Tools Command Prompt for VS 2022.bat (should be in Start Menu > Visual Studio 2022 menu folder). Pay attention not to use any other Command Prompt.

Install third party software

• Download Python 3.10 installer from https://www.python.org/downloads/ and install it with adding to PATH.
• Download Git installer from https://git-scm.com/download/win and install it.

Clone source code and prepare libraries

Open x64 Native Tools Command Prompt for VS 2022.bat, go to BuildPath and run

git clone --recursive https://github.com/AyuGram/AyuGramDesktop.git tdesktop
tdesktop\Telegram\build\prepare\win.bat

You may encounter an error saying that your IP is not allowed - simply turn on VPN.

Build the project

Go to BuildPath\tdesktop\Telegram and run

configure.bat x64 -D TDESKTOP_API_ID=2040 -D TDESKTOP_API_HASH=b18441a1ff607e10a989891a5462e627

• Open BuildPath\tdesktop\out\Telegram.slnx in Visual Studio 2022
• Select Telegram project and press Build > Build Telegram (Debug and Release configurations)
• The result AyuGram.exe will be located in D:\TBuild\tdesktop\out\Debug (and Release)

If you encounter issue like error C1090: PDB API call failed, error code '12' on Release build, apply the following patch in tdesktop/cmake folder (via pwsh or manually):
