Building from source

Table of Contents

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
  2. 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:

    git submodule update --init --recursive

  2. Create a build directory:

    mkdir build
cd build

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

    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:

    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.

    cmake --build .

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

    cmake --build . --config Release

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

    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.
