##Build instructions for Qt Creator 3.5.1 under Ubuntu 12.04

###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

You need to install g++ version 4.9 manually by such commands

  • sudo add-apt-repository ppa:ubuntu-toolchain-r/test
  • sudo apt-get update
  • sudo apt-get install gcc-4.9 g++-4.9
  • sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 21
  • sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 21

###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

make
sudo make install

####PortAudio 19

./configure
make
sudo make 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

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

####OpenSSL

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

git clone https://github.com/openssl/openssl
cd openssl
git checkout OpenSSL_1_0_1-stable
./config
make
sudo make install

####libxkbcommon (required for Fcitx Qt plugin)

sudo apt-get install xutils-dev bison python-xcbgen
git clone https://github.com/xkbcommon/libxkbcommon.git
cd libxkbcommon
./autogen.sh --disable-x11
make
sudo make install

####Qt 5.6.0, slightly patched

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

git clone git://code.qt.io/qt/qt5.git qt5_6_0
cd qt5_6_0
git checkout 5.6
perl init-repository --module-subset=qtbase,qtimageformats
git checkout v5.6.0
cd qtimageformats && git checkout v5.6.0 && cd ..
cd qtbase && git checkout v5.6.0 && cd ..

#####Apply the patch

cd qtbase && git apply ../../../tdesktop/Telegram/Patches/qtbase_5_6_0.diff && cd ..

#####Building library

Install some packages for Qt (see /home/user/TBuild/Libraries/qt5_6_0/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 libffi-dev

OPENSSL_LIBS='-L/usr/local/ssl/lib -lssl -lcrypto' ./configure -prefix "/usr/local/tdesktop/Qt-5.6.0" -release -force-debug-info -opensource -confirm-license -qt-zlib -qt-libpng -qt-libjpeg -qt-freetype -qt-harfbuzz -qt-pcre -qt-xcb -qt-xkbcommon-x11 -no-opengl -static -openssl-linked -nomake examples -nomake tests
make -j4
sudo make install

building (make command) will take really long time.

git clone https://chromium.googlesource.com/linux-syscall-support breakpad/src/third_party/lss
cd breakpad
./configure
make
sudo make install

###Building Telegram codegen utilities

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

mkdir -p Linux/obj/codegen_style/Debug
cd Linux/obj/codegen_style/Debug
/usr/local/tdesktop/Qt-5.6.0/bin/qmake CONFIG+=debug ../../../../Telegram/build/qmake/codegen_style/codegen_style.pro
make
mkdir -p ../../codegen_numbers/Debug
cd ../../codegen_numbers/Debug
/usr/local/tdesktop/Qt-5.6.0/bin/qmake CONFIG+=debug ../../../../Telegram/build/qmake/codegen_numbers/codegen_numbers.pro
make

###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/tdesktop/Qt-5.6.0/bin/qmake > Qt 5.6.0 (Qt-5.6.0) > Apply
  • Tools > Options > Build & Run > Kits tab > Desktop (default) > change Qt version to Qt 5.6.0 (Qt-5.6.0) > Apply
  • 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)
