Build instructions for CMake under Ubuntu 14.04

Prepare folder

Choose an empty folder for the future build, for example /home/user/TBuild. It will be named BuildPath in the rest of this document.

Obtain your API credentials

You will require api_id and api_hash to access the Telegram API servers. To learn how to obtain them click here.

Install software and required packages

You will need GCC 8 installed. To install them and all the required dependencies run

sudo apt-get install software-properties-common -y && \
sudo apt-get install git libexif-dev liblzma-dev libz-dev libssl-dev \
libgtk2.0-dev libice-dev libsm-dev libicu-dev libdrm-dev dh-autoreconf \
autoconf automake build-essential libxml2-dev libass-dev libfreetype6-dev \
libgpac-dev libsdl1.2-dev libtheora-dev libtool libva-dev libvdpau-dev \
libvorbis-dev libxcb1-dev libxcb-image0-dev libxcb-shm0-dev \
libxcb-xfixes0-dev libxcb-keysyms1-dev libxcb-icccm4-dev libatspi2.0-dev \
libxcb-render-util0-dev libxcb-util0-dev libxcb-xkb-dev libxrender-dev \
libasound-dev libpulse-dev libxcb-sync0-dev libxcb-randr0-dev libegl1-mesa-dev \
libx11-xcb-dev libffi-dev libncurses5-dev pkg-config texi2html bison yasm \
zlib1g-dev xutils-dev python-xcbgen chrpath gperf -y --force-yes && \
sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y && \
sudo apt-get update && \
sudo apt-get install gcc-8 g++-8 -y && \
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 60 && \
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-8 60 && \
sudo update-alternatives --config gcc && \
sudo add-apt-repository --remove ppa:ubuntu-toolchain-r/test -y

You can set the multithreaded make parameter by running

MAKE_THREADS_CNT=-j8

Building the project

Go to BuildPath/tdesktop/Telegram and run (using your api_id and api_hash)

./configure.sh -D TDESKTOP_API_ID=YOUR_API_ID -D TDESKTOP_API_HASH=YOUR_API_HASH -D DESKTOP_APP_USE_PACKAGED=OFF

To make Debug version go to BuildPath/tdesktop/out/Debug and run

make $MAKE_THREADS_CNT

To make Release version go to BuildPath/tdesktop/out/Release and run

make $MAKE_THREADS_CNT

You can debug your builds from Qt Creator, just open BuildPath/tdesktop/CMakeLists.txt, configure to a separate directory with correct options and launch with debug.
