• openssl libcrypto https://www.openssl.org/
• pthreads

Download

• Git tree: https://github.com/yellowhatcrow/yhc-miner
  • Clone with git clone https://github.com/yellowhatcrow/yhc-miner

Build

Basic *nix build instructions:

• just use ./initiate_builder OR

Use with caution will autostart and remove older deps.

• just use ./initiate_builder --force OR

Note for Debian/Ubuntu users:

Require Deps: automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++

Note for pi64 users:

 ./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.
  • 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 "yhcminer --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.
