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**NB** These are outdated, please refer to [Building using Xcode][xcode] instructions.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

### Clone source code

By git – in Terminal go to **/Users/user/TBuild** and run

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

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

    git checkout dev

#### Prepare latest cmake

Download the [latest sources](https://cmake.org/download/) and unpack to **/Users/user/TBuild/Libraries/macold**

    ./bootstrap
    make -j4
    sudo make install

### 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.

#### 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 qt5_3_2
    cd qt5_3_2
    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/macold/qt5_3_2/qtbase**, run:

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

From **/Users/user/TBuild/Libraries/macold/qt5_3_2/qtimageformats**, run:

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

##### Building library

Go to **/Users/user/TBuild/Libraries/macold/qt5_3_2** and run:

    OPENSSL_LIBS="/Users/user/TBuild/Libraries/macold/openssl-1.0.1h/libssl.a /Users/user/TBuild/Libraries/macold/openssl-1.0.1h/libcrypto.a" ./configure -prefix "/usr/local/macold/Qt-5.3.2" -debug-and-release -force-debug-info -opensource -confirm-license -static -opengl desktop -openssl-linked -I "/Users/user/TBuild/Libraries/macold/openssl-1.0.1h/include" -nomake examples -nomake tests -platform macx-g++
    make -j4
    sudo make -j4 install

building (**make** command) will take really long time.

#### Google Crashpad

.. the same as modern ..

##### Build crashpad

    cd third_party/mini_chromium
    git clone https://chromium.googlesource.com/chromium/mini_chromium
    cd mini_chromium
    git checkout 7c5b0c1ab4
    git apply ../../../../../../tdesktop/Telegram/Patches/macold/mini_chromium.diff
    cd ../../gtest
    git clone https://chromium.googlesource.com/external/github.com/google/googletest gtest
    cd gtest
    git checkout d62d6c6556
    cd ../../../

    build/gyp_crashpad.py -Dmac_deployment_target=10.6
    ninja -C out/Debug
    ninja -C out/Release

#### Prepare GYP

.. the same as modern ..

### 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)
