Working Vagrant environment for building Telegram desktop client. Based on Ubuntu 12.04. Should be placed under TBuild directory. Then just vagrant up && ./build_debug.sh.

build_debug.sh

#!/bin/bash

vagrant ssh -c "\
cd /vagrant/tdesktop/Telegram && gyp/refresh.sh && cd ../out/Debug && make -j4"

build_release.sh

#!/bin/bash

vagrant ssh -c "\
cd /vagrant/tdesktop/Telegram && gyp/refresh.sh && cd ../out/Debug && make -j4"

provision.sh

#!/bin/bash
# Usage: ./provision.sh [build-step..]
# Build-steps:
# build_libs, gcc6, cmake, zlib, opus, va, vdpau, ffmpeg, portaudio, openal, openssl, 
# xcbcommon, qt5, breakpad, gyp.
# If build-steps are not specified everything is made from scratch by default.

# Utility function.
# Check if element is in array.
# Usage: contains $element $array
function contains {
    local e
    for e in ${@:2}; do
        [[ "$e" == "$1" ]] && return 0;
    done
    return 1
