Summary

This is a fork of the cpp-ethereum project that works on macOS 10.12.x (Sierra) and 10.13.x (High Sierra).

This specific repo was forked from Genoil's cpp-ethereum Repo, which itself was forked from the official aforementined repo. This fork was made in response to the lack of maintained macOS support from Genoil's fork and from the Official Homebrew Ethereum Formula.

The conversation that led to this fork can be found at https://github.com/ethereum/homebrew-ethereum/issues/116.

Pre-Installation Instructions

Download and install the latest version of

• Xcode
  • For Nvidia Cards - Xcode 7.3 Command Line Tools at https://download.developer.apple.com/Developer_Tools/Command_Line_Tools_OS_X_10.11_for_Xcode_7.3/Command_Line_Tools_OS_X_10.11_for_Xcode_7.3.dmg
  • Afterwards run sudo xcode-select --switch /Library/Developer/CommandLineTools
  • For everything else - Xcode 8.3.3 or newer at https://developer.apple.com/xcode
• Homebrew from https://brew.sh

Installation Instructions

1. Download this fork of cpp-ethereum

git clone --recursive https://github.com/ArtSabintsev/Ethminer-for-macOS

2. Enter the downloaded folder and create and enter the build directory.

mkdir build; cd build

3. Run one of the the following cmake calls on the root directory from within the build directory.

• This will also install all the homebrew dependencies that you'll need.

// RUN THIS IF YOU HAVE AN NVIDIA CARD AND WANT PROPRIETARY DRIVERS.
cmake -DBUNDLE=cudaminer -DETHSTRATUM=1 -DETHASHCUDA=ON ..

// RUN THIS IF YOU HAVE ANY CARD (INCL. NVIDIA) AND WANT THE OPEN SOURCE 'OpenCL' DRIVERS.
cmake -DBUNDLE=miner -DETHSTRATUM=1 ..

4. Run make next:

make -j8

5. Afterwards, run cmake again, but on your current directory, the build directory.

cmake --build .

Launching ethminer

Once installation succedes, go to the ethminer directory (from the build directory). Type in ./ethminer and you're good to go.

Issues

nvcc fatal : The version ('90000') of the host compiler ('Apple clang') is not supported

Ensure you have installed Xcode CLT 7.3 and switched using the xcode-select command as outline above. Verify that clang has been downgraded via clang --version

nvcc fatal : Unsupported gpu architecture 'compute_20'

Modify the generated CMAKE file at build/libethash-cuda/CMakeFiles/ethash-cuda.dir/ethash-cuda_generated_ethash_cuda_miner_kernel.cu.o.Release.cmake

Around set(CUDA_NVCC_FLAGS)

Remove the following flag: -gencode arch=compute_20,code=sm_20

Run the make command again.

Support

While I am a full-time programmer, I do not use C/C++ in my daily life, at least not at a level where I can actively develop this fork. I will do my best to support the fork.
