##Build instructions for Xcode 7.2.1

**NB** These are outdated, please refer to [Building using Xcode][xcode] instructions.

###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.

**IMPORTANT** You are required to build and install Qt 5.6.0 from the [Xcode 7](building-xcode.md) instructions first.

###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, then go to **/Users/user/TBuild/tdesktop** and run

    git checkout mac32

###Prepare libraries

In your build Terminal run

    MACOSX_DEPLOYMENT_TARGET=10.6

to set minimal supported OS version to 10.6 for future console builds.

####zlib 1.2.8

####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

####Qt 5.3.2, slightly patched
#####Get the source code

In Terminal go to **/Users/user/TBuild/Libraries** and run:

    git clone git://code.qt.io/qt/qt5.git QtStatic
    cd QtStatic
    git checkout 5.3
    perl init-repository --module-subset=qtbase,qtimageformats
    git checkout v5.3.2
    cd qtimageformats && git checkout v5.3.2 && cd ..
    cd qtbase && git checkout v5.3.2 && cd ..

#####Apply the patch

From **/Users/user/TBuild/Libraries/QtStatic/qtbase**, run:

    git apply ../../../tdesktop/Telegram/Patches/qtbase_5_3_2.diff

From **/Users/user/TBuild/Libraries/QtStatic/qtimageformats**, run:

    git apply ../../../tdesktop/Telegram/Patches/qtimageformats_5_3_2.diff

#####Building library

Go to **/Users/user/TBuild/Libraries/QtStatic** and run:

    ./configure -debug-and-release -force-debug-info -opensource -confirm-license -static -opengl desktop -nomake examples -nomake tests -platform macx-g++
    make -j4
    sudo make -j4 install

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 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)
