#PSA

The solo mining portion of Zogminer has moved (temporarily) to a clone of the zcash repo found at https://github.com/nginnever/zcash We will make a PR to zcash when it is ready. This repo can still serve as pool miner.

ZCash-gpu-miner

An OpenCL Zcash miner solving Equihash PoW.

Project Status

Status: In active development

Check the project's roadmap to see what's happening at the moment and what's planned next.

Building

First make sure OpenCL is correctly installed in your system. If you are having issues, take a look at our Ubuntu Guide or Fedora Guide.

If you are getting /usr/bin/ld: cannot find -lOpenCL, the error has to do with the driver installing libOpenCL.so as libOpenCL.so.1. You can create a symlink:

$ sudo ln -s /usr/lib/libOpenCL.so.1 /usr/lib/libOpenCL.so

Or for people that do not want to mess with this:

$ sudo apt-get install ocl-icd-opencl-dev

Unix

Install the dependencies. On Debian/Ubuntu-based systems:

$ sudo apt-get install \
      build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python \
      zlib1g-dev wget bsdmainutils automake opencl-headers \
      mesa-common-dev

On Fedora-based systems:

$ sudo dnf install \
      git pkgconfig automake autoconf ncurses-devel python wget \
      gtest-devel gcc gcc-c++ libtool patch opencl-headers mesa-libGL-devel

Fetch our repository with git and run fetch-params.sh like so:

$ git clone https://github.com/nginnever/zogminer.git
$ cd zogminer/
$ ./zcutil/fetch-params.sh

Ensure you have successfully installed all system dependencies as described above. Then run the build, e.g.:

$ ./zcutil/build.sh -j$(nproc)

This should compile our dependencies and build zcash-miner. (Note: if you don't have nproc, then substitute the number of your processors.)

Running

Run GPU test miner

$ ./src/zcash-miner -G

Usage:

$ ./src/zcash-miner -help

Stratum

./src/zcash-miner -G -stratum="stratum+tcp://<address>:<port>" -user=<user> -password=<pass>

Solo mine ZCash

This currently only works on the zcash branch https://github.com/nginnever/zcash

zcashd -G -allgpu (this will load all your cards and solo mine) zcashd -G -deviceid= (this will run a specific card) zcashd -G -allgpu -genproclimit=2 (this will run two threads per card. If you're card has 4gb or more this can work)

First create or modify ~/.zcash/zcash.conf with the following:

testnet=1
addnode=betatestnet.z.cash
rpcuser=username
rpcpassword=password
gen=1
GPU=1
deviceid=<device> (default: 0)

Next run zcashd:

./src/zcashd
