Monero C++ Library

This project is a library for working with Monero wallets in C++ by wrapping Monero Core's C++ wallet, wallet2.

In addition, this project conforms to an API specification intended to be intuitive, robust, and for long-term use in the Monero project.

This library may be used to build Monero-related applications, such as GUIs, libraries in other languages (e.g. monero-java), or a compliant REST/JSON-RPC API.

Main Features

• Manage Monero wallets which connect to a daemon
• Query wallet transactions, transfers, and outputs by their many attributes
• Receive notifications as a wallet is synchronized, when blocks are added to the chain, or when the wallet sends or receives transfers

Building a Dynamic / Shared Library

The source code in this project may be built as a dynamic or shared library for use on a target platform (e.g. Linux, Mac, Windows, etc). For example, the associated Java library depends on a dynamic library built from this project to support a wallet using Java JNI.

Build Steps

1. Setup Boost
   1. Download and extract the boost 1.69.0 source code zip from https://www.boost.org/users/download/ to ./external/boost-sdk/.
   2. cd ./external/boost-sdk/
   3. ./bootstraph.sh
   4. ./b2
   5. Copy .a files from ./external/boost-sdk/bin.v2/libs/*/link-static/* to ./external-libs/boost according to CMakeLists.txt.
2. Setup OpenSSL
   1. Download and extract the latest OpenSSL source code zip from https://github.com/openssl/openssl to ./external/openssl-sdk/.
   2. Build for your system.
      Mac: installed through boost at /usr/local/opt/openssl/lib
   3. Copy libcrypto.a and libssl.a ./external-libs/openssl.
3. Setup Monero Core
   1. Initialize submodules: git submodule update --init --recursive
   2. cd ./submodules/monero-core
   3. Modify CMakeLists.txt: option(BUILD_GUI_DEPS "Build GUI dependencies." ON).
   4. Build twice to create libwallet_merged.a in addition to other .a libraries: make release-static -j8.
   5. Copy .a files from ./submodules/monero-core/build/release/* to ./external-libs/monero-core according to CMakeLists.txt.
4. Setup hidapi
   1. Download the latest hidapi source code from https://github.com/signal11/hidapi.
   2. Build hidapi for your system.
      Mac requires autoreconf: brew install automake
   3. Copy libhidapi.a to ./external-libs/hidapi.
5. Setup libsodium
   1. Build libsodium for your system.
   2. Copy libsodium.a to ./external-libs/libsodium.
      Mac: installed through homebrew at /usr/local/Cellar/libsodium/1.0.17/lib/libsodium.a
6. Build libmonero-cpp.dylib to ./build: ./bin/build-libmonero-cpp.sh.

These build steps aspire to be automated further.
