+# Icecream Setup for macOS to build Chromium
+
+This instructions shows how to use icecream on macOS to distribute build jobs on Linux nodes in the network.
+Right now it does not explain how to share the build jobs on other macOS machines in the network.
+
+## Instructions on macOS
+
+Install the prerequisites (I recommend using homebrew)
+
+```bash
+$ xcode-select --install
+$ brew install lzo
+```
+
+Clone this repository, this will take a while because it contains a binary copy
+of a clang toolchain (which is a gross thing to keep in git, I know)
+
+```bash
+$ git clone https://github.com/darktears/icecream-mac.git /path/to/chromium/src/icecream
+```
+
+Install the daemon. This will create a launchd plist which will be run on startup.
+The argument passed to the `install.sh` script is the scheduler to connect to.
+
+```bash
+$ sudo /path/to/chromium/src/icecream/install.sh IP_OF_SCHEDULER
+```
+You can uninstall it with :
+```bash
+$ sudo /path/to/chromium/src/icecream/uninstall.sh
+```
+With this the icecream daemon is launched when macOS starts or if it stops.
+
+You now need to setup some environment variable. In your .bashrc add :
+
+```bash
+$ export ICECC_VERSION=/path/to/chromium/src/icecream/clang_darwin_on_linux.tar.gz
+$ export ICECC_CLANG_REMOTE_CPP=1
+```
+
+Setup your args.gn
+
+gn args gen /my/build
+
+and add :
+```bash
+disable_precompiled_headers = true
+clang_base_path = "//icecream"
+clang_use_chrome_plugins = false 
+```
+
+## Setup the Linux nodes
+
+At the moment you need a custom version of icecream to be able to build the jobs sent from macOS. This is so that icecream
+can handle compiling ObjectiveC files.
+
+```bash
+$ git clone https://github.com/darktears/icecream.git
+$ cd icecream
+$ ./autogen.sh
+$ ./configure --prefix=/where/you/want/to/install
+$ make && make install
+```
+
+If you're using a Debian-based distro, or basically any distro that uses sysv rc files to start iceccd and reads icecc.conf to configure the daemon, you can tell it to use your iceccd binary instead of the system-wide one. As root:
+
+Stop iceccd if it's running. > sudo service iceccd stop
+Edit icecc.conf and add a line like this: DAEMON="/path/to/your/new/iceccd"
+Restart iceccd. > sudo service iceccd start
+
+That's it.
