CPUMiner-Multi

This is a multi-threaded CPU miner for Minotaur and MinotaurX. It supports SegWit.

It's a fork of tpruvot's cpuminer, in turn forked from pooler's miner.

See AUTHORS for list of contributors.

Dependencies

Download

Build

Basic *nix build instructions:

  • just use ./build.sh OR

 ./autogen.sh	# only needed if building from git repo
 ./nomacro.pl	# only needed if building on Mac OS X or with Clang
 ./configure CFLAGS="*-march=native*" --with-crypto --with-curl
 # Use -march=native if building for a single machine
 make

Note for Debian/Ubuntu users:

 apt-get install automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++

Note for OS X users:

 brew install openssl curl
 ./build.sh # if curl was installed to /usr/local/opt, else update build.sh paths in darwin section

Note for pi64 users:

 ./autogen.sh
 ./configure --disable-assembly CFLAGS="-Ofast -march=native" --with-crypto --with-curl

Notes for AIX users:

  • To build a 64-bit binary, export OBJECT_MODE=64

  • GNU-style long options are not supported, but are accessible via configuration file

Architecture-specific notes:

  • ARM:

    • No runtime CPU detection. The miner can take advantage of some instructions specific to ARMv5E and later processors, but the decision whether to use them is made at compile time, based on compiler-defined macros.

    • To use NEON instructions, add "-mfpu=neon" to CFLAGS.

  • x86:

    • The miner checks for SSE2 instructions support at runtime, and uses them if they are available.

  • x86-64:

    • The miner can take advantage of AVX, AVX2 and XOP instructions, but only if both the CPU and the operating system support them.

      • Linux supports AVX starting from kernel version 2.6.30.

      • FreeBSD supports AVX starting with 9.1-RELEASE.

      • Mac OS X added AVX support in the 10.6.8 update.

      • Windows supports AVX starting from Windows 7 SP1 and Windows Server 2008 R2 SP1.

    • The configure script outputs a warning if the assembler doesn't support some instruction sets. In that case, the miner can still be built, but unavailable optimizations are left off.

Usage instructions

Run "cpuminer --help" to see options.

Connecting through a proxy

Use the --proxy option.

To use a SOCKS proxy, add a socks4:// or socks5:// prefix to the proxy host Protocols socks4a and socks5h, allowing remote name resolving, are also available since libcurl 7.18.0.

If no protocol is specified, the proxy is assumed to be a HTTP proxy. When the --proxy option is not used, the program honors the http_proxy and all_proxy environment variables.
