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.
Change Log
----------
v3.6.2
SHA accceleration is now supported on AMD Ryzen CPUs when compiled from source,
Windows binaries not yet available.
Fixed groestl algo.
Fixed dmd-gr (Diamond) algo.
Fixed lLbry compile error on Ryzen.
Added SHA support to m7m algo.
Hodl support for CPUs without AES has been removed, use legacy version.
v3.6.1
Fixed data alignment issue that broke lyra2rev2 AVX2 on Windows.

* The "compact" format is a representation of a whole

* The most significant 8 bits are the unsigned exponent of base 256.
* This exponent can be thought of as "number of bytes of N".
* The lower 23 bits are the mantissa.
* Bit number 24 (0x800000) represents the sign of N.
* N = (-1^sign) * mantissa * 256^(exponent-3)
*
* Satoshi's original implementation used BN_bn2mpi() and BN_mpi2bn().
* MPI uses the most significant bit of the first byte as sign.
* Thus 0x1234560000 is compact (0x05123456)
* and 0xc0de000000 is compact (0x0600c0de)
*
* Bitcoin only uses this "compact" format for encoding difficulty
* targets, which are unsigned 256bit quantities. Thus, all the
* complexities of the sign bit and using base 256 are probably an
* implementation accident.
