MWC Miner

A standalone mining implementation intended for mining MWC against a running MWC node.

Supported Platforms

At present, only mining plugins for linux-x86_64 and MacOS exist. This will likely change over time as the community creates more solvers for different platforms.

Step 1:

## Go to root directory ##
cd /

## Install OpenSSL 1.1.1 and set as default ##
cd /
sudo apt-get -y remove openssl
git clone --depth 1 --branch OpenSSL_1_1_1g https://github.com/openssl/openssl.git
cd openssl
./config zlib '-Wl,-rpath,$(LIBRPATH)'
make
sudo make install
sudo ldconfig -v
source ~/.bashrc
exec bash

Step 2

## Install libssl-dev ##
sudo apt-get -y update
sudo apt-get -y install libssl-dev

## Install pkg-config ##
sudo apt-get -y update
sudo apt-get -y install pkg-config

## Clone and Build ##
cd /
git clone https://github.com/zoltan151/MWC-miner.git
cd MWC-miner
git submodule update --init
cargo build --release --features opencl --verbose
./install_ocl_plugins.sh
cp MWC-miner.toml target/release/MWC-miner.toml
cd target/release

You must install OpenCL libraries for your operating system before. If you just need to compile them (for development or testing purposes) build MWC-miner the following way:

cargo build --features opencl

Build errors

See Troubleshooting

What was built?

A successful build gets you:

• target/debug/MWC-miner - the main MWC-miner binary
• target/debug/plugins/* - mining plugins

Make sure you always run MWC-miner within a directory that contains a MWC-miner.toml configuration file.

While testing, put the MWC-miner binary on your path like this:

export PATH=/path/to/MWC-miner/dir/target/debug:$PATH

You can then run MWC-miner directly.

Configuration

MWC-miner can be further configured via the MWC-miner.toml file. This file contains contains inline documentation on all configuration options, and should be the first point of reference.

You should always ensure that this file exists in the directory from which you're running MWC-miner.
