Introduction

Metaverse(MVS) is a decentralised system based on the blockchain technology, through which, a network of smart properties, digital identities and value intermediators are established.

Metaverse Features:

Building MVS

Compiler requirements

Compilier Minimum Version
gcc/g++ 5.0
clang++ 3.4 (8.0.0)
MSVC 19.0 (VS2015)

C++ compiler support C++14 standard or newer. Dependencies of MVS binaris are static linked (including libstdc++).

Toolchain requirements

  • cmake 3.0+
  • git
  • automake (speck256k1/ZeroMQ)
$ yum/brew/apt-get install git cmake
$ yum/brew/apt-get install autoconf automake libtool pkg-config

Setup Library Dependencies

By install_dependencies.sh

Installing ZeroMQ secp256k1 automatically by:

$ sudo ./install_dependencies.sh

Installing boost upnp automatically by:

$ sudo ./install_dependencies.sh --build-boost --build-upnpc

Manually

boost 1.56+

$ sudo yum/brew/apt-get install libboost-all-dev

Download Boost 1.69.0.

zeromq 4.2.1+

$ wget https://github.com/zeromq/libzmq/releases/download/v4.2.1/zeromq-4.2.1.tar.gz
$ tar -xzvf zeromq-4.2.1.tar.gz
$ cd zeromq-4.2.1
$ ./autogen.sh
$ ./configure
$ make -j4
$ sudo make install && sudo ldconfig

server/explorer requires ZeroMQ.

secp256k1

$ git clone https://github.com/mvs-live/secp256k1
$ cd secp256k1
$ ./autogen.sh
$ ./configure --enable-module-recovery
$ make -j4
$ sudo make install && sudo ldconfig

Sometimes we may got the following compile error undefined reference to '__gmpn_sub_n' ... See more details here #issue209

$ ./configure --enable-module-recovery --with-bignum=no

miniupnpc

$ wget http://miniupnp.tuxfamily.org/files/miniupnpc-2.0.tar.gz
$ tar -xzvf miniupnpc-2.0.tar.gz
$ cd miniupnpc-2.0
$ make -j4
$ sudo INSTALLPREFIX=/usr/local make install && sudo ldconfig

blockchain/network requires upnp if specified.

Building

$ git clone https://github.com/mvs-org/metaverse.git
$ cd metaverse && mkdir build && cd build
$ cmake -DUSE_UPNP=OFF ..
$ make -j4
$ make install

To enable UPnP, use cmake .. instead.

optional:

$ make test (should install boost_unit_test_framework)
$ make doc  (should install doxygen and graphviz)

Run it

  • mvsd - server program
    Runs a full metaverse node in the global peer-to-peer network.

  • mvs-cli - client program
    Sent your request to the server, the server will process it and return response to your client.

$ cd bin
$ ./mvsd
$ ./mvs-cli
$ ./mvs-cli getnewaccount -h
$ ./mvs-cli $command $params $options

Read More Command line usage and Configuration file.

Building/Run under docker

Preparation

Install Docker.

wget qO https://get.docker.com/ | sh

Build metaverse image

git clone https://github.com/mvs-org/metaverse.git
cd metaverse
docker build -t metaverse -f Dockerfile .

Where is your built image? It’s in your machine’s local Docker image registry:

docker images

Run && Test

Start docker container

docker run -p 8820:8820 metaverse

Test

curl -X POST --data '{"jsonrpc":"2.0","method":"getinfo","params":[],"id":25}' http://127.0.0.1:8820/rpc/v2

Execute mvs-cli commands

Run mvs-cli commands via docker exec command. Example:

docker exec metaverse mvs-cli getinfo

Build for raspberry pi

Cross compile mvs using Docker in ubuntu 16.04

you need to change to root when executing the flowing command.

env

check versin first, linux kerne and docker version:

host docker >= 17.05.0-ce
host kernel >= 4.8

install qemu:

apt-get install qemu-user-static

way1

Clone the mvs source. then enter mvs source directory, then run:

// for arm 64 (eg: aarch64, armv8(and abover))
sudo bash ./cross-build.sh arm64

When everything ok, the binary file and .so/.a file will be found in output directory.

You can’t perform that action at this time.
