##Build instructions for Qt Creator 3.1.2 under Ubuntu 14.04

###Prepare

  • Install git by command sudo apt-get install git in Terminal
  • Install g++ by command sudo apt-get install g++ in Terminal
  • Install Qt Creator from Downloads page

For 32 bit Ubuntu you need to install g++ version 4.8 manually by such commands

  • sudo add-apt-repository ppa:ubuntu-toolchain-r/test
  • sudo apt-get update
  • sudo apt-get install gcc-4.8 g++-4.8
  • sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 20
  • sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.8 20

###Prepare folder

Choose a folder for the future build, for example /home/user/TBuild There you will have two folders, Libraries for third-party libs and tdesktop (or tdesktop-master) for the app.

###Clone source code

By git – in Terminal go to /home/user/TBuild and run

git clone https://github.com/telegramdesktop/tdesktop.git

or download in ZIP and extract to /home/user/TBuild rename tdesktop-master to tdesktop to have /home/user/TBuild/tdesktop/Telegram/Telegram.pro project

###Prepare libraries

Install dev libraries

sudo apt-get install libexif-dev liblzma-dev libz-dev libssl-dev libogg-dev libopus-dev libopusfile-dev

Install OpenAL Soft

In Terminal go to /home/user/TBuild/Libraries and run

git clone git://repo.or.cz/openal-soft.git

then go to /home/user/TBuild/Libraries/openal-soft/build and run

cmake -D LIBTYPE:STRING=STATIC ..
make
sudo make install

####Qt 5.3.1, slightly patched

http://download.qt-project.org/official_releases/qt/5.3/5.3.1/single/qt-everywhere-opensource-src-5.3.1.tar.gz

Extract to /home/user/TBuild/Libraries, rename qt-everywhere-opensource-src-5.3.1 to QtStatic to have /home/user/TBuild/Libraries/QtStatic/qtbase folder

Apply patch – copy (with overwrite!) everything from /home/user/TBuild/tdesktop/_qt_5_3_1_patch/ to /home/user/TBuild/Libraries/QtStatic/

#####Building library

Install some packages for Qt (see /home/user/TBuild/Libraries/QtStatic/qtbase/src/plugins/platforms/xcb/README)

sudo apt-get install libxcb1-dev libxcb-image0-dev libxcb-keysyms1-dev libxcb-icccm4-dev libxcb-render-util0-dev libxcb-util0-dev libxrender-dev libasound-dev libpulse-dev libxcb-sync0-dev libxcb-xfixes0-dev libxcb-randr0-dev libx11-xcb-dev

In Terminal go to /home/user/TBuild/Libraries/QtStatic and there run

./configure -release -opensource -confirm-license -qt-xcb -no-opengl -static -nomake examples -skip qtquick1 -skip qtdeclarative
y
make
sudo make install

building (make command) will take really long time.

###Building Telegram Desktop

  • Launch Qt Creator, all projects will be taken from /home/user/TBuild/tdesktop/Telegram
  • Tools > Options > Build & Run > Qt Versions tab > Add > File System /usr/local/Qt-5.3.1/bin/qmake > Qt 5.3.1 (Qt-5.3.1) > Apply
  • Tools > Options > Build & Run > Kits tab > Desktop (default) > change Qt version to Qt 5.3.1 (Qt-5.3.1) > Apply
  • Open MetaStyle.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediateStyle and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediateStyle and build for Debug
  • Open MetaEmoji.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediateEmoji and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediateEmoji and build for Debug
  • Open MetaLang.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediateLang and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediateLang and build for Debug
  • Open Telegram.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediate and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediate and build for Debug, if GeneratedFiles are not found click Run qmake from Build menu and try again
  • Open Updater.pro, configure project with paths /home/user/TBuild/tdesktop/Linux/DebugIntermediateUpdater and /home/user/TBuild/tdesktop/Linux/ReleaseIntermediateUpdater and build for Debug
  • Release Telegram build will require removing CUSTOM_API_ID definition in Telegram.pro project and may require changing paths in /home/user/TBuild/tdesktop/Telegram/FixMake.sh or /home/user/TBuild/tdesktop/Telegram/FixMake32.sh for static library linking fix, static linking applies only on second Release build (first uses old Makefile)
