##Build instructions for Qt Creator 2.7 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 Ubuntu Software Center

###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

####OpenSSL 1.0.1g

http://www.openssl.org/source/ > Download openssl-1.0.1h.tar.gz (4.3 Mb)

Extract openssl-1.0.1h.tar.gz to /home/user/TBuild/Libraries

#####Building library

In Terminal go to /home/user/TBuild/Libraries/openssl-1.0.1h and there run

./config
make
sudo make install

####liblzma

http://tukaani.org/xz/ > Download xz-5.0.5.tar.gz

Extract to /home/user/TBuild/Libraries

#####Building library

In Terminal go to /home/user/TBuild/Libraries/xz-5.0.5 and there run

./configure
make
sudo make install

####zlib 1.2.8

http://zlib.net/ > Download zlib source code, version 1.2.8, tar.gz format

Extract to /home/user/TBuild/Libraries

#####Building library

In Terminal go to /home/user/TBuild/Libraries/zlib-1.2.8 and there run

./configure
make
sudo make install

####libexif 0.6.20

Get sources from https://github.com/telegramdesktop/libexif-0.6.20, by git – in Terminal go to /home/user/TBuild/Libraries and run

git clone https://github.com/telegramdesktop/libexif-0.6.20.git

or download in ZIP and extract to /home/user/TBuild/Libraries, rename libexif-0.6.20-master to libexif-0.6.20 to have /home/user/TBuild/Libraries/libexif-0.6.20/configure script

#####Building library

In Terminal go to /home/user/TBuild/Libraries/libexif-0.6.20 and there run

./configure
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 libxcb-image0-dev
sudo apt-get install libxcb-keysyms1-dev
sudo apt-get install libxcb-icccm4-dev
sudo apt-get install libxcb-render-util0-dev
sudo apt-get install libxcb-util0-dev
sudo apt-get install libxrender-dev
sudo apt-get install libpulse-dev

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

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

building (make command) will take really long time.

In Ubuntu under Parallels Desktop there was a problem with libGL, bad symlink /usr/lib/x86_64-linux-gnu/mesa/libGL.so to unexisting file, had to fix it manually like this

sudo ln -sf libGL.so.1 /usr/lib/x86_64-linux-gnu/mesa/libGL.so

because only /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1 existed.

#####Building pulseaudio plugin

In Terminal go to /home/user/TBuild/Libraries/QtStatic/qtmultimedia/src/plugins/pulseaudio and run

qmake pulseaudio.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/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
• 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 for static library linking fix
