##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, 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. ####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

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)
