1. Requirements:
|
|
---------------
|
|
|
|
Intel Core2 or newer, or AMD Steamroller or newer CPU. ARM CPUs are not
|
|
supported.
|
|
64 bit Linux operating system. Apple is not supported.
|
|
|
|
2. 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. Regardless compiling is trivial if you
|
|
follow the instructions.
|
|
|
|
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 compiler error messages,
|
|
they will give a clue as to the missing package.
|
|
|
|
The following command should install everything you need on Debian based
|
|
distributions such as Ubuntu. Fedora and other distributions may have similar
|
|
but different package names.
|
|
|
|
$ sudo apt-get install build-essential automake libssl-dev libcurl4-openssl-dev libjansson-dev libgmp-dev zlib1g-dev git
|
|
|
|
SHA support on AMD Ryzen CPUs requires gcc version 5 or higher and
|
|
openssl 1.1.0e or higher. Add one of the following to CFLAGS for SHA
|
|
support depending on your CPU and compiler version:
|
|
|
|
"-march=native" is always the best choice
|
|
|
|
"-march=znver1" for Ryzen 1000 & 2000 series, znver2 for 3000.
|
|
|
|
"-msha" Add SHA to other tuning options
|
|
|
|
Additional instructions for static compilalation can be found here:
|
|
https://lxadm.com/Static_compilation_of_cpuminer
|
|
Static builds should only considered in a homogeneous HW and SW environment.
|
|
Local builds will always have the best performance and compatibility.
|
|
|
|
3. Download cpuminer-opt
|
|
------------------------
|
|
|
|
Download the source code for the latest realease from the official repository.
|
|
|
|
https://github.com/JayDDee/cpuminer-opt/releases
|
|
|
|
Extract the source code.
|
|
|
|
$ tar xvzf cpuminer-opt-x.y.z.tar.gz
|
|
|
|
|
|
Alternatively it can be cloned from git.
|
|
|
|
$ git clone https://github.com/JayDDee/cpuminer-opt.git
|
|
|
|
4. Build cpuminer-opt
|
|
---------------------
|
|
|
|
It is recomended to Build with default options, this will usuallly
|
|
produce the best results.
|
|
|
|
$ ./build.sh to build on Linux or execute the following commands.
|
|
|
|
or
|
|
|
|
$ ./autogen.sh
|
|
$ CFLAGS="-O3 -march=native -Wall" ./configure --with-curl
|
|
$ make -j n
|
|
|
|
n is the number of threads.
|
|
|
|
5. Start mining.
|
|
----------------
|
|
|
|
$ ./cpuminer -a algo -o url -u username -p password
|
|
|
|
|
|
Windows
|
|
-------
|
|
|
|
See also INSTAL_WINDOWS
|
|
|
|
The following procedure is obsolete and uses an old compiler.
|
|
|
|
Precompiled Windows binaries are built on a Linux host using Mingw
|
|
with a more recent compiler than the following Windows hosted procedure.
|
|
|
|
Building on Windows prerequisites:
|
|
|
|
msys
|
|
mingw_w64
|
|
Visual C++ redistributable 2008 X64
|
|
openssl
|
|
|
|
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 build.sh to build on Windows or execute the following commands.
|
|
|
|
./autogen.sh
|
|
CFLAGS="-O3 -march=native -Wall" ./configure --with-curl
|
|
make
|
|
|
|
Start mining
|
|
|
|
cpuminer.exe -a algo -o url -u user -p password
|
|
|
|
The following tips may be useful for older AMD CPUs.
|
|
|
|
AMD CPUs older than Steamroller, 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.
