Build Options

Only Official Builds Supported

  • The fastest and most recommended method of installation is through Docker management
  • Only official release builds are recommended and supported for use on the main network
  • Builds created from git should be done using the available tags - building from branches is not recommended, including building off the master branch as that is used during development of features

Official release builds

OS Binaries
Each release cycle official builds of the node for Linux, MacOS and Windows are generated and linked to from the related GitHub Release as well as on Nano.org.

Other sources
The node can be also be installed from other sources including Docker and RHEL/CentOS rpm: 

sudo yum-config-manager --add-repo https://repo.nano.org/nanocurrency.repo
sudo yum install nanocurrency

This installs nano_node to bin.

Beta builds

OS Binaries
Each beta release cycle official beta builds of the node for Linux, MacOS and Windows are released and can be found at https://beta.nano.org. Go to the Beta Network page for more details.

Other sources
The beta node can be also be installed from other sources including Docker and RHEL/CentOS rpm: 

sudo yum-config-manager --add-repo https://repo.nano.org/nanocurrency-beta.repo
sudo yum install nanocurrency-beta

This installs nano_node-beta to bin.

Nano Folder

Contents

The Nano folder contains: wallets file (wallets.ldb), log files, ledger file (data.ldb), config file (config.json) and related lock files.

Locations

OS Location
Windows C:\Users\<user>\AppData\Local\Nano\
OSX /Users/<user>/Library/Nano/
Linux /home/<user>/Nano/
Moving folder locations

Some users desire to change the blockchain download location. A solution is available for the no gui nano_node (see https://github.com/nanocurrency/nano-node/issues/79), but no concrete solution is available for the GUI client. However, a workaround can be acheived via the use of symbolic links. Below is a short tutorial for Windows builds:

  1. Rename/delete the Nano folder in your appdata Local folder (if you haven't run the wallet yet, skip this step). This is necessary because the command to create a symbolic link in windows will fail if the the input directory already exists.
  2. Decide on where you want to store the blockchain and create a symbolic link. The command is (in an administrative command-prompt): mklink /d "C:\Users\<user>\AppData\Local\Nano\" "E:\Some\Other\Directory". This command creates a symbolic link for a directory (/d) that 'redirects' all requests for files/directories in the Local\Nano folder to the Other\Directory. This means that a file created in the input directory will actually be in the output directory (on the other disk).
  3. Verify it works. Create a file in your Nano folder in your appdata, and you should see it appear in the directory you linked it to (and vice-versa). If you have old wallets or a partially-downloaded blockchain, copy them back into the local directory. Start the wallet.

Build Instructions - General

Unsupported configuration

  • This documentation is intended only for developers of the Nano Node software, and will not result in a supported configuration. End-users are advised to use releases.
  • The fastest and most recommended method of installation is through Docker.
  • Running node as a service.
  • To manage a node, use RPC commands or the CLI.

Requirements

Required Source

  • Boost 1.67 extracted to [boost.src] (OR sh nano-node/util/build_prep/bootstrap_boost.sh -m)
  • (wallet) Qt 5.x open source edition extracted to [qt.src]
  • Nano node source in [nano-node.src]

Required build tools

  • (macOS) XCode >= 7.3
  • (Windows) Visual Studio 2015
  • (Windows) NSIS package builder
  • (*nix) Clang >= 3.5 or GCC >= 5
  • CMake

Boost

Option 1

Inside nano-node directory run:

sh util/build_prep/bootstrap_boost.sh -m

This will build the required Boost libraries at /usr/local/boost/.

Option 2

Inside [boost.src] run: 

./bootstrap.sh --with-libraries=filesystem,log,program_options,thread
./b2 --prefix=[boost] --build-dir=[boost.build] link=static install
If on Windows: an additional b2 option address-model=64 for x64 builds should be included.

QT Wallet

In [qt.build] execute: 

[qt.src]/configure -shared -opensource -nomake examples -nomake tests -confirm-license  -prefix [qt]
make
make install
If on Windows: use nmake instead of make.

Node

CMake variables

Format: cmake -D VARNAME=VARVALUE

  • BOOST_ROOT=\[boost\] (/usr/local/boost/ if bootstrapped)
  • CMAKE_BUILD_TYPE=Release (default)
  • ACTIVE_NETWORK=nano_live_network (default)
  • Qt5_DIR=[qt]lib/cmake/Qt5 (to build GUI wallet)
  • NANO_GUI=ON (to build GUI wallet)
  • ENABLE_AVX2=ON, optional PERMUTE_WITH_GATHER=ON, optional PERMUTE_WITH_SHUFFLES=ON (for CPU with AXV2 support, choose fastest method for your CPU with https://github.com/sneves/blake2-avx2/)
  • CRYPTOPP_CUSTOM=ON (more conservative building of Crypto++ for wider range of systems)
  • NANO_SIMD_OPTIMIZATIONS=OFF (Enable CPU-specific SIMD optimization: SSE/AVX or NEON, e.g.)
  • NANO_SECURE_RPC=ON (to build node with TLS)

Build Node

  • git submodule update --init --recursive
  • Generate with cmake then build with your compiler
  • (*nix) to build node without GUI execute: make nano_node
  • (*nix) to build wallet with GUI execute: make nano_wallet

Building a package

  • (macOS) cpack -G "DragNDrop"
  • (Windows) cpack -G "NSIS"
  • (*nix) cpack -G "TBZ2"

Testing Nano

  • In order to run the tests, the corresponding CMake variable must be set: -D NANO_TEST=ON.
  • With this variable set, make will also build test files, and will produce core_test and slow_test binaries, which can be executed like ./core_test.
  • To run a node on the test network, set CMake variable: -DACTIVE_NETWORK=nano_test_network

Beta Network Participation

  • More information can be found on the Beta Network page
  • To run a node on the beta network, set CMake variable: -DACTIVE_NETWORK=nano_beta_network
