Compile instruction for Linux and Windows are at the bottom of this file.
|
||||
cpuminer-opt now supports HW SHA acceleration available on AMD Ryzen CPUs.
|
||||
This feature requires recent SW including GCC version 5 or higher and
|
||||
openssl version 1.1 or higher. It may also require using "-march=znver1"
|
||||
compile flag.
|
||||
|
||||
HW SHA support is only available when compiled from source, Windows binaries
|
||||
are not yet available.

Compile Instructions
|
||||
--------------------
|
||||
|
||||
Building on linux prerequisites:
|
||||
|
||||
It is assumed users know how to install packages on their system and
|
||||
be able to compile standard source packages. This is basic Linux and
|
||||
beyond the scope of cpuminer-opt.
|
||||
|
||||
Make sure you have the basic development packages installed.
|
||||
Here is a good start:
|
||||
|
||||
http://askubuntu.com/questions/457526/how-to-install-cpuminer-in-ubuntu
|
||||
|
||||
Install any additional dependencies needed by cpuminer-opt. The list below
|
||||
are some of the ones that may not be in the default install and need to
|
||||
be installed manually. There may be others, read the error messages they
|
||||
will give a clue as to the missing package.
|
||||
|
||||
The folliwing command should install everything you need on Debian based
|
||||
packages:
|
||||
|
||||
sudo apt-get install build-essential libssl-dev libcurl4-openssl-dev libjansson-dev libgmp-dev automake
|
||||
|
||||
Building on Linux, see below for Windows.
|
||||
|
||||
Dependencies
|
||||
|
||||
build-essential (for Ubuntu, Development Tools package group on Fedora)
|
||||
automake
|
||||
libjansson-dev
|
||||
libgmp-dev
|
||||
libcurl4-openssl-dev
|
||||
libssl-dev
|
||||
pthreads
|
||||
zlib
|
||||
|
||||
SHA support on AMD Ryzen CPUs requires gcc version 5 or higher and openssl 1.1
|
||||
or higher. Additional compile options may also be required such as
|
||||
"-march-znver1" or "-msha".
|
||||
|
||||
Extract cpuminer source.
|
||||
|
||||
tar xvzf cpuminer-opt-x.y.z.tar.gz
|
||||
cd cpuminer-opt-x.y.z
|
||||
|
||||
Run ./build.sh to build on Linux or execute the following commands.
|
||||
|
||||
./autogen.sh
|
||||
CFLAGS="-O3 -march=native -Wall" CXXFLAGS="$CFLAGS -std=gnu++11" ./configure --with-curl
|
||||
make
|
||||
|
||||
Start mining.
|
||||
|
||||
./cpuminer -a algo ...
|
||||
|
||||
Building on Windows prerequisites:
|
||||
|
||||
msys
|
||||
mingw_w64
|
||||
Visual C++ redistributable 2008 X64
|
||||
openssl, not sure about this
|
||||
|
||||
Install msys and mingw_w64, only needed once.
|
||||
|
||||
Unpack msys into C:\msys or your preferred directory.
|
||||
|
||||
Install mingw_w64 from win-builds.
|
||||
Follow instructions, check "msys or cygwin" and "x86_64" and accept default
|
||||
existing msys instalation.
|
||||
|
||||
Open a msys shell by double clicking on msys.bat.
|
||||
Note that msys shell uses linux syntax for file specifications, "C:\" is
|
||||
mounted at "/c/".
|
||||
|
||||
Add mingw bin directory to PATH variable
|
||||
PATH="/c/msys/opt/windows_64/bin/:$PATH"
|
||||
|
||||
Instalation complete, compile cpuminer-opt
|
||||
|
||||
Unpack cpuminer-opt source files using tar from msys shell, or using 7zip
|
||||
or similar Windows program.
|
||||
|
||||
In msys shell cd to miner directory.
|
||||
cd /c/path/to/cpuminer-opt
|
||||
|
||||
Run winbuild.sh to build on Windows or execute the following commands.
|
||||
|
||||
./autogen.sh
|
||||
CFLAGS="-O3 -march=native -Wall" CXXFLAGS="$CFLAGS -std=gnu++11 -fpermissive" ./configure --with-curl
|
||||
make
|
||||
|
||||
The following tips may be useful for older AMD CPUs.
|
||||
|
||||
AMD CPUs older than Piledriver, including Athlon x2 and Phenom II x4, are not
|
||||
supported by cpuminer-opt due to an incompatible implementation of SSE2 on
|
||||
these CPUs. Some algos may crash the miner with an invalid instruction.
|
||||
Users are recommended to use an unoptimized miner such as cpuminer-multi.
|
||||
|
||||
Some users with AMD CPUs without AES_NI have reported problems compiling
|
||||
with build.sh or "-march=native". Problems have included compile errors
|
||||
and poor performance. These users are recommended to compile manually
|
||||
specifying "-march=btver1" on the configure command line.
|
||||
|
||||
Support for even older x86_64 without AES_NI or SSE2 is not availble.
