##Build instructions for Xcode 6.4

###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

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

In Termianl go to /Users/user/TBuild/Libraries/libiconv-1.14 and run

./configure --enable-static
make
sudo make install

Then in Terminal go to /Users/user/TBuild/Libraries/ffmpeg-2.6.3 and run

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install automake fdk-aac git lame libass libtool libvorbis libvpx opus sdl shtool texi2html theora wget x264 xvid yasm

Extract to /Users/user/TBuild/Libraries, rename qt-everywhere-opensource-src-5.5.0 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_5_0_patch/ to /Users/user/TBuild/Libraries/QtStatic/

• OR copy /Users/user/TBuild/tdesktop/_qt_5_5_0_patch.diff to /Users/user/TBuild/Libraries/QtStatic/, go there in Terminal and run

  git apply _qt_5_5_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 -no-openssl -securetransport -nomake examples -nomake tests -platform macx-clang
make -j4 module-qtbase module-qtimageformats
sudo make module-qtbase-install_subtargets module-qtimageformats-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 6.1 - Custom Compiler Flags > Other C / C++ Flags > Release)
