Compiler requirements

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

C++ compiler support C++14. Using c++ -v to check c++ version.

• Simple guide to upgrade GCC.
• Upgrade guide for Debian/ubuntuu
• Upgrade guide for OSX
• Upgrade guide for windows

Dependencies of MVS are static linked (including libstdc++). Thus, there is no extra dependency after compilation. Recommends Ubuntu 16.04/CentOS 7.2/Visual Studio 2015 to develop/debug/build MVS.

Toolchain requirements

• cmake 3.0+
• git
• automake (speck256k1/ZeroMQ required)

$ yum/brew/apt-get install git cmake
$ yum/brew/apt-get install autoconf automake libtool pkg-config

Build MVS

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

optional:

$ make test
$ make doc

Needs to configure Library Dependencies firstly.

Library Dependencies

Installing by bash script (sudo required).

$ ./install_dependencies.sh
