macos Build Instructions

Important

We don't recommend macos for rippled production use at this time. Currently, the Ubuntu platform has received the highest level of quality assurance and testing. That said, macos is suitable for many development/test tasks.

Prerequisites

You'll need macos 10.8 or later.

To clone the source code repository, create branches for inspection or modification, build rippled using clang, and run the system tests you will need these software components:

• XCode
• Homebrew
• Boost
• other misc utilities and libraries installed via homebrew

Install Software

Install XCode

If not already installed on your system, download and install XCode using the appstore or by using this link.

For more info, see "Step 1: Download and Install the Command Line Tools" here

The command line tools can be installed through the terminal with the command:

xcode-select --install

Install Homebrew

"Homebrew installs the stuff you need that Apple didn’t."

Open a terminal and type:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

For more info, see "Step 2: Install Homebrew" here

Install Dependencies Using Homebrew

brew will generally install the latest stable version of any package, which should satisfy the the minimum version requirements for rippled.

brew update
brew install git cmake pkg-config protobuf openssl ninja

Build Boost

Boost 1.70 or later is required.

We want to compile boost with clang/libc++

Download a release

Extract it to a folder, making note of where, open a terminal, then:

./bootstrap.sh
./b2 cxxflags="-std=c++14"  visibility=global

Create an environment variable BOOST_ROOT in one of your rc files, pointing to the root of the extracted directory.

Dependencies for Building Source Documentation

Source code documentation is not required for running/debugging rippled. That said, the documentation contains some helpful information about specific components of the application. For more information on how to install and run the necessary components, see this document

Build

Clone the rippled repository

From a shell:

git clone git@github.com:ripple/rippled.git
cd rippled

For a stable release, choose the master branch or one of the tagged releases listed on [GitHub](https://github.com/ripple/rippled/releases GitHub).

git checkout master

or to test the latest release candidate, choose the release branch.

git checkout release

If you are doing development work and want the latest set of untested features, you can consider using the develop branch instead.

git checkout develop

Configure Library Paths

If you didn't persistently set the BOOST_ROOT environment variable to the root of the extracted directory above, then you should set it temporarily.

For example, assuming your username were Abigail and you extracted Boost 1.70.0 in /Users/Abigail/Downloads/boost_1_70_0, you would do for any shell in which you want to build:

export BOOST_ROOT=/Users/Abigail/Downloads/boost_1_70_0

Generate and Build

For simple command line building we recommend using the Unix Makefile or Ninja generator with cmake. All builds should be done in a separate directory from the source tree root (a subdirectory is fine). For example, from the root of the ripple source tree:

mkdir my_build
cd my_build

followed by:

cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug ..

or

cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Debug ..

CMAKE_BUILD_TYPE can be changed as desired for Debug vs. Release builds (all four standard cmake build types are supported).

Once you have generated the build system, you can run the build via cmake:

cmake --build . -- -j 4

the -j parameter in this example tells the build tool to compile several files in parallel. This value should be chosen roughly based on the number of cores you have available and/or want to use for building.

When the build completes succesfully, you will have a rippled executable in the current directory, which can be used to connect to the network (when properly configured) or to run unit tests.

If you prefer to have an XCode project to use for building, ask CMake to generate that instead:

cmake -GXcode ..

After generation succeeds, the xcode project file can be opened and used to build/debug. However, just as with other generators, cmake knows how to build using the xcode project as well:

cmake --build . -- -jobs 4

This will invoke the xcodebuild utility to compile the project. See xcodebuild --help for details about build options.

Optional installation

If you'd like to install the artifacts of the build, we have preliminary support for standard CMake installation targets. We recommend explicitly setting the installation location when configuring, e.g.:

cmake -DCMAKE_INSTALL_PREFIX=/opt/local ..

(change the destination as desired), and then build the install target:

cmake --build . --target install -- -jobs 4

Options During Configuration:

The CMake file defines a number of configure-time options which can be examined by running cmake-gui or ccmake to generated the build. In particular, the unity option allows you to select between the unity and non-unity builds. unity builds are faster to compile since they combine multiple sources into a single compiliation unit - this is the default if you don't specify. nounity builds can be helpful for detecting include omissions or for finding other build-related issues, but aren't generally needed for testing and running.

• -Dunity=ON to enable/disable unity builds (defaults to ON)
• -Dassert=ON to enable asserts
• -Djemalloc=ON to enable jemalloc support for heap checking
• -Dsan=thread to enable the thread sanitizer with clang
• -Dsan=address to enable the address sanitizer with clang

Several other infrequently used options are available - run ccmake or cmake-gui for a list of all options.

Unit Tests (Recommended)

rippled builds a set of unit tests into the server executable. To run these unit tests after building, pass the --unittest option to the compiled rippled executable. The executable will exit with summary info after running the unit tests.
