Kepka - Unofficial Telegram Desktop fork from pro.cxx community

This is the complete source code and the build instructions for the Kepka's alpha version based on the Telegram API and the MTProto secure protocol.

Build instructions

Linux, macOS

What you need to have installed:

• Qt 5.9+ (with private modules, like qtbase5-private-dev)
• OpenSSL (conan installs this if you use conan)
• OpenAL-soft
• FFmpeg with swscale and swresample libs
• zlib
• opus (libopus-dev)

Debian/Ubuntu:

# apt-get install libssl-dev libavformat-dev libavdevice-dev libswscale-dev libavutil-dev libpulse-dev libasound2-dev libswresample-dev libavresample-dev libopus-dev qtbase5-private-dev zlib1g-dev libopenal-dev libavcodec-dev libopenal-data libopenal1

You most likely have to rebuild ffmpeg with --enable-swresample --enable-swscale

After that, go to the next section.

Fedora:

# dnf install rpm-build rpmdevtools mock mock-rpmfusion-free

Add yourself to mock group (you must run this only for the first time after installing mock):

sudo usermod -a -G mock $(whoami)

You need to relogin to your system or run:

newgrp mock

Create RPM build base directories:

rpmdev-setuptree

Download sources:

spectool -g -R kepka.spec

Generate SRPM:

rpmbuild -bs kepka.spec

Start mock build sequence:

mock -r fedora-$(rpm -E %fedora)-$(uname -m)-rpmfusion_free --rebuild ~/rpmbuild/SRPMS/kepka*.src.rpm

Configuring and building

Provide paths to OpenAL-soft and Qt5 in CMAKE_PREFIX_PATH variable when configuring.

ccache -o sloppiness=pch_defines,time_macros
mkdir _conan_build_
cd _conan_build_
conan install .. --build missing
cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_PREFIX_PATH="/usr/local/opt/qt5/;/usr/local/opt/openal-soft" ..
ninja

Windows

Install vcpkg (no need to integrate, just install), python 3.5, cmake, Qt 5.9 or later and Visual Studio 2017 or later, and set the following environment variables:

• QTDIR: directory where Qt binary distribution is installed, e.g. C:\Qt\5.9.1\msvc2017_64
• VCPKG: directory where VCPKG is installed, e.g. C:\vcpkg

After that, execute the following cmd commands from Visual Studio developer command prompt:

$ set PATH=c:\Python35;%PATH%
$ "%VCPKG%\vcpkg" install --triplet x64-windows openal-soft openssl opus zlib ffmpeg
$ mkdir build
$ cd build
$ set PATH=%QTDIR%\bin;%PATH%
$ cmake -G"Visual Studio 15 2017 Win64" -DCMAKE_TOOLCHAIN_FILE="%VCPKG%\scripts\buildsystems\vcpkg.cmake" -DCMAKE_BUILD_TYPE=RelWithDebInfo ..
$ cmake --build . --config RelWithDebInfo
