Prepare folder

Choose a folder for the future build, for example D:\TBuild\. There you will have two folders, Libraries for third-party libs and tdesktop for the app.

All commands (if not stated otherwise) will be launched from VS2015 x86 Native Tools Command Prompt.bat (should be in Start Menu > Programs > Visual Studio 2015 menu folder).

A note on D:\TBuild

In case you don't have a D drive, or prefer to use another working directory. Since all of the examples and commands here are using the D drive, you might find it more comfortable to map the drive to a folder you of your choice. For example, to map D:\ to C:\base_folder_for_telegram_dev, open the cmd and execute: subst D: C:\base_folder_for_telegram_dev.

Clone source code

Go to D:\TBuild

D:
cd TBuild

and run

git clone --recursive https://github.com/telegramdesktop/tdesktop.git
mkdir Libraries

Prepare libraries

OpenSSL

Go to D:\TBuild\Libraries and run

git clone https://github.com/openssl/openssl.git
cd openssl
git checkout OpenSSL_1_0_1-stable
perl Configure VC-WIN32 --prefix=D:\TBuild\Libraries\openssl\Release
ms\do_ms
nmake -f ms\nt.mak
nmake -f ms\nt.mak install
cd ..
git clone https://github.com/openssl/openssl.git openssl_debug
cd openssl_debug
git checkout OpenSSL_1_0_1-stable
perl Configure debug-VC-WIN32 --prefix=D:\TBuild\Libraries\openssl_debug\Debug
ms\do_ms
nmake -f ms\nt.mak
nmake -f ms\nt.mak install

make
make install

Qt 5.6.2, slightly patched

• Install Python 3.3.2 from https://www.python.org/download/releases/3.3.2 > Windows x86 MSI Installer (3.3.2)
• Go to D:\TBuild\Libraries and run

git clone git://code.qt.io/qt/qt5.git qt5_6_2
cd qt5_6_2
perl init-repository --module-subset=qtbase,qtimageformats
git checkout v5.6.2
cd qtimageformats && git checkout v5.6.2 && cd ..
cd qtbase && git checkout v5.6.2 && cd ..

Apply the patch

cd qtbase && git apply ../../../tdesktop/Telegram/Patches/qtbase_5_6_2.diff && cd ..

Install Windows SDKs

If you didn't install Windows SDKs before, you need to install them now. To install the SDKs just open Telegram solution at D:\TBuild\tdesktop\Telegram.sln (jump here to generate Telegram.sln) and on startup Visual Studio 2015 will popup dialog box and ask to download and install extra components (including Windows 7 SDK).

If you already have Windows SDKs then find the library folder and correct it at configure's command below (like C:\Program Files (x86)\Windows Kits\8.0\Lib\win8\um\x86).

Building library

Go to D:\TBuild\Libraries\qt5_6_2 and run

configure -debug-and-release -force-debug-info -opensource -confirm-license -static -I "D:\TBuild\Libraries\openssl\Release\include" -L "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib" -l Gdi32 -no-opengl -openssl-linked OPENSSL_LIBS_DEBUG="D:\TBuild\Libraries\openssl_debug\Debug\lib\ssleay32.lib D:\TBuild\Libraries\openssl_debug\Debug\lib\libeay32.lib" OPENSSL_LIBS_RELEASE="D:\TBuild\Libraries\openssl\Release\lib\ssleay32.lib D:\TBuild\Libraries\openssl\Release\lib\libeay32.lib" -mp -nomake examples -nomake tests -platform win32-msvc2015
nmake
nmake install

building (nmake command) will take really long time.

Qt5Package

https://visualstudiogallery.msdn.microsoft.com/c89ff880-8509-47a4-a262-e4fa07168408

Download, close all VS2015 instances and install for VS2015

Google Breakpad

Breakpad is a set of client and server components which implement a crash-reporting system.

Installation

depot_tools

Go to D:\TBuild\Libraries and run

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
cd depot_tools
gclient

If you get errors like

Cannot rebase: You have unstaged changes.
Please commit or stash them.
Failed to update depot_tools.

run git reset --hard HEAD and execute gclient again

Breakpad

cd ..
mkdir breakpad && cd breakpad
..\depot_tools\fetch breakpad
..\depot_tools\gclient sync
xcopy src\src\* src /s /i
rmdir src\src /s /q

Build

• Open D:\TBuild\Libraries\breakpad\src\client\windows\breakpad_client.sln in VS2015
• Change Treat WChar_t As Built in Type to No in all projects & configurations (should be in Project -> Properties -> C/C++ -> Language)
• Change Treat Warnings As Errors to No in all projects & configurations (should be in Project -> Properties -> C/C++ -> General)
• Build Debug configuration
• Build Release configuration

Building Telegram Desktop

Setup GYP/Ninja and generate VS solution

• Download Ninja binaries and unpack them to D:\TBuild\Libraries\ninja to have D:\TBuild\Libraries\ninja\ninja.exe
• Go to D:\TBuild\Libraries and run

git clone https://chromium.googlesource.com/external/gyp
cd gyp
git checkout a478c1ab51
SET PATH=%PATH%;D:\TBuild\Libraries\gyp;D:\TBuild\Libraries\ninja;
cd ..\..\tdesktop\Telegram

Also, actually add D:\TBuild\Libraries\ninja\ (not just for running the gyp command) to your path environment variable, since Telegram needs it for the build process.

If you want to pass a build define (like TDESKTOP_DISABLE_AUTOUPDATE or TDESKTOP_DISABLE_NETWORK_PROXY), call set TDESKTOP_BUILD_DEFINES=TDESKTOP_DISABLE_AUTOUPDATE,TDESKTOP_DISABLE_NETWORK_PROXY,... (comma seperated string)

After, call gyp\refresh.bat (python 2.7 needed)

Configure VS

• Launch VS2015 for configuring Qt5Package
• QT5 > Qt Options > Add
  • Version name: Qt 5.6.22Win32
  • Path: D:\TBuild\Libraries\qt5_6_2\qtbase
    • If you made a network map, here you should use the real path! (e.g C:\base_folder_for_telegram_dev or what you used at the beginning)
• Default Qt/Win version: Qt 5.6.2 Win32 – OK - You may need to restart Visual Studio for this to take effect.

Build the project

• File > Open > Project/Solution > D:\TBuild\tdesktop\Telegram\Telegram.sln
• Select Telegram project and press Build > Build Telegram (Debug and Release configurations)
• The result Telegram.exe will be located in D:\TBuild\tdesktop\out\Debug (and Release)
