* The default ccache directory is ~/.ccache. You can see a list of configuration options by calling ccache alone. brew install ccacheĬonfigure ccache to use a different cache size with ccache -M. The Android emulator build scripts will probe for it and use it if available, which can speed up incremental builds considerably. It is highly recommended to install the ‘ccache’ build tool on your development machine(s). The ninja build engine is part of our repository: export PATH = $PATH : $HOME / emu - master - dev / prebuilts / ninja / darwin - x86 / The rebuild script does a complete clean build. You can pass the flag -help to the rebuild script to get an idea of which options you can pass in.

If all goes well you should have a freshly build emulator in the objs directory.

Now run: cd external / qemu & android / rebuild. Sync the repo (and get some coffee, or a have a good nap.) repo sync -j 8Ĭongratulations! You have all the sources you need. You can initialize repo as follows: mkdir -p $HOME/emu-master-dev & cd $HOME/emu-master-dev export PATH = $PATH : $HOME / binĭo not forget to add this to your. Make sure to add $HOME/bin to your path, if it is not already there. com / git - repo - downloads / repo > $HOME / bin / repo mkdir $HOME / binĬurl http :// commondatastorage. platform / Developer / SDKs Obtaining repoįirst we need to obtain the repo tool. Īnd extract this to your install, for example: export XCODE_PATH = $ ( xcode - select - print - path 2 >/ dev / null ) If you are within Google, first install gsutil, after which you can: gsutil cp gs :// emu - dev - development / MacOSX10. The toolchain specifically looks for the MacOS 10.13 SDK, and will fail to configure if you do not have it available. Usually this prints /Applications/Xcode.app/Contents/Developer. You can obtain the installation directory as follows: export XCODE_PATH=$(xcode-select -print-path 2>/dev/null) You can validate that you have an Xcode version available by running: xcodebuild - version Note: Xcode is usually installed in /Applications/Xcode.app you might run into unexpected issues if this is not the case. You will only be able to launch the emulator with the -gpu off flag. Note: You can compile with any version of Xcode > 10.1, but might run into issues around Qt. The next step is to to accept the license and install the command line tools. Move Xcode to the Applications folder and you are good to go. Simply double-click the xip file and it will extract the Xcode application.

From the App store, or use this direct link to get xcode 10.1.

Make sure to get the proper santa exceptions.

We use xcode 10.1 and encourage you to use the same version. We have pinned the compiler and MacOS SDK on the build bots to make sure we do not encounter unexpected issues. Throughout the emulator code base and documentation we ofter refer to MacOS as Darwin. This document describes how to get started with emulator development under MacOS.
