##Build instructions for Xcode 5.1.1

###Prepare folder

Choose a folder for the future build, for example /Users/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 /Users/user/TBuild and run

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

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

###Prepare libraries

In your build Terminal run

MACOSX_DEPLOYMENT_TARGET=10.7

to set minimal supported OS version to 10.7 for future console builds.

####OpenSSL 1.0.1g

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

git clone https://github.com/telegramdesktop/openssl-xcode.git

or download in ZIP and extract to /Users/user/TBuild/Libraries, rename openssl-xcode-master to openssl-xcode to have /Users/user/TBuild/Libraries/openssl-xcode/openssl.xcodeproj project

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

Extract openssl-1.0.1h.tar.gz and copy everything from openssl-1.0.1h to /Users/user/TBuild/Libraries/openssl-xcode to have /Users/user/TBuild/Libraries/openssl-xcode/include

#####Building library

• Open /Users/user/TBuild/Libraries/openssl-xcode/openssl.xcodeproj with Xcode
• Product > Build

####liblzma

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

Extract to /Users/user/TBuild/Libraries

#####Building library

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

./configure
make
sudo make install

####zlib 1.2.8

Using se system lib

####libexif 0.6.20

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

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

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

#####Building library

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

./configure
make
sudo make install

####OpenAL Soft

Get sources by git – in Terminal go to /Users/user/TBuild/Libraries and run

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

to have /Users/user/TBuild/Libraries/openal-soft/CMakeLists.txt

#####Building library

In Terminal go to /Users/user/TBuild/Libraries/openal-soft/build and there run

cmake -D LIBTYPE:STRING=STATIC -D CMAKE_OSX_DEPLOYMENT_TARGET:STRING=10.7 ..
make
sudo make install

####libogg 1.3.2

Get sources from http://xiph.org/downloads/ – in ZIP and extract to /Users/user/TBuild/Libraries

#####Building library

In Terminal go to /Users/user/TBuild/Libraries/libogg-1.3.2 and there run

./configure
make
sudo make install

####Opus codec, opusfile

Download sources opus-1.1.tar.gz and opusfile-0.6.tar.gz from http://www.opus-codec.org/downloads/, extract to /Users/user/TBuild/Libraries and rename to have /Users/user/TBuild/Libraries/opus/configure and /Users/user/TBuild/Libraries/opusfile/configure

#####Building libraries

Download pkg-config 0.28 from http://pkg-config.freedesktop.org, extract it to /Users/user/TBuild/Libraries

In Terminal go to /Users/user/TBuild/Libraries/pkg-config-0.28 and run

./configure --with-internal-glib
make
sudo make install

then go to /Users/user/TBuild/Libraries/opus and there run

./configure
make
sudo make install

then go to /Users/user/TBuild/Libraries/opusfile and there run

./configure
make
sudo make install

####Qt 5.4.0, slightly patched

http://download.qt-project.org/official_releases/qt/5.4/5.4.0/single/qt-everywhere-opensource-src-5.4.0.tar.gz

Extract to /Users/user/TBuild/Libraries, rename qt-everywhere-opensource-src-5.4.0 to QtStatic to have /Users/user/TBuild/Libraries/QtStatic/qtbase folder

Apply patch:

• OR copy (with overwrite!) everything from /Users/user/TBuild/tdesktop/_qt_5_4_0_patch/ to /Users/user/TBuild/Libraries/QtStatic/

• OR copy /Users/user/TBuild/tdesktop/_qt_5_4_0_patch.diff to /Users/user/TBuild/Libraries/QtStatic/, go there in Terminal and run

  git apply _qt_5_4_0_patch.diff

#####Building library

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

./configure -debug-and-release -opensource -confirm-license -static -opengl desktop -nomake examples -nomake tests -platform macx-clang
make -j4 module-qtbase module-qtimageformats module-qtmultimedia
sudo make module-qtbase-install_subtargets module-qtimageformats-install_subtargets module-qtmultimedia-install_subtargets

building (make command) will take really long time.

###Building Telegram Desktop

• Launch Xcode, all projects will be taken from /Users/user/TBuild/tdesktop/Telegram
• Open MetaStyle.xcodeproj and build for Debug (Release optionally)
• Open MetaEmoji.xcodeproj and build for Debug (Release optionally)
• Open MetaLang.xcodeproj and build for Debug (Release optionally)
• Open Telegram.xcodeproj and build for Debug
• Build Updater target as well, it is required for Telegram relaunch
• Release Telegram build will require removing CUSTOM_API_ID definition in Telegram target settings (Apple LLVM 5.1 - Custom Compiler Flags > Other C / C++ Flags > Release)
