Requirements

This project uses CMake and Hunter package manager.

Common

1. CMake >= 3.5
2. Git
3. Perl, needed to build OpenSSL
4. CUDA Toolkit >= 9.0 (optional, install if you want NVidia CUDA support)

Linux

1. GCC version >= 4.8, tested on GCC compiler 7.5.0
2. CMake version 3.21.5

wget https://github.com/Kitware/CMake/releases/download/v3.21.5/cmake-3.21.5.tar.gz
tar -zxvf cmake-3.21.5.tar.gz
cd cmake-3.21.5
./bootstrap
make
sudo make install

3. DBUS development libs if building with -DETHDBUS. E.g. on Ubuntu run:

sudo apt install libdbus-1-dev

OpenCL support on Linux

If you're planning to use OpenCL on Linux you have to install the OpenGL libraries. E.g. on Ubuntu run:

sudo apt-get install mesa-common-dev

If you want to use locally installed ROCm-OpenCL package, use build flag -DUSE_SYS_OPENCL=ON with cmake config.

macOS

1. GCC version >= TBF

Windows

1. Visual Studio 2017; Community Edition works fine. Make sure you install MSVC 2015 toolkit (v140).

Instructions

1. Make sure git submodules are up to date:

   shellCopy

   git submodule update --init --recursive
   

2. Create a build directory:

   shellCopy

   mkdir build
   cd build
   

3. Configure the project with CMake. Check out the additional configuration options.

   shellCopy

   cmake ..
   

   Note: On Windows, it's possible to have issues with VS 2017 default compilers, due to CUDA expecting a specific toolset version; in that case, use the VS 2017 installer to get the VS 2015 compilers and pass the -T v140 option:

   shellCopy

   cmake .. -G "Visual Studio 15 2017 Win64"
   # or this if you have build errors in the CUDA step
   cmake .. -G "Visual Studio 15 2017 Win64" -T v140
   

4. Build the project using CMake Build Tool Mode. This is a portable variant of make.

   shellCopy

   cmake --build .
   

   Note: On Windows, it is possible to have compiler issues if you don't specify the build config. In that case use:

   shellCopy

   cmake --build . --config Release
   

5. Generate the executable

   shellCopy

   make all
   

   will find the executable in ethminer/ethminer in the build directory

6. (Optional, Linux only) Install the built executable:

   shellCopy

   sudo make install
   

Windows-specific script

Complete sample Windows batch file - adapt it to your system. Assumes that:

• it's placed one folder up from the ethminer source folder
• you have CMake installed
• you have Perl installed

@echo off
setlocal

rem add MSVC in PATH
call "%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\Common7\Tools\VsMSBuildCmd.bat"

rem add Perl in PATH; it's needed for OpenSSL build
set "PERL_PATH=C:\Perl\perl\bin"
set "PATH=%PERL_PATH%;%PATH%"

rem switch to ethminer's source folder
cd "%~dp0\ethminer\"

if not exist "build\" mkdir "build\"

rem For CUDA 9.x pass also `-T v140`
cmake -G "Visual Studio 15 2017 Win64" -H. -Bbuild -DETHASHCL=ON -DETHASHCUDA=ON -DAPICORE=ON ..
cmake --build . --config Release --target package

endlocal
pause

CMake configuration options

Pass these options to CMake configuration command, e.g.

cmake .. -DETHASHCUDA=ON -DETHASHCL=OFF

• -DETHASHCL=ON - enable OpenCL mining, ON by default.
• -DETHASHCUDA=ON - enable CUDA mining, ON by default.
• -DAPICORE=ON - enable API Server, ON by default.
• -DBINKERN=ON - install AMD binary kernels, ON by default.
• -DETHDBUS=ON - enable D-Bus support, OFF by default.
• -DUSE_SYS_OPENCL=ON - Use system OpenCL, OFF by default, unless on macOS. Specify to use local ROCm-OpenCL package.

Disable Hunter

If you want to install dependencies yourself or use system package manager you can disable Hunter by adding -DHUNTER_ENABLED=OFF to the configuration options.
