This is a multi-threaded OpenCL/CPU miner, fork of pooler's cpuminer.
Always specify local scratchpad file (ex. -l scratchpad.bin)!
To mine on the first available GPU:
minerd -a wildkeccak_ocl -o stratum+tcp://url_to_server:7777 -u 1EmWGnwhydr3S2vRWQbbefh1hgDKgMjdMGe43ZgdPhdARhNBRkUMuD4YzLA2nyYG8tg2HKCCBg4aDamJKypRQWW1Ca2kSV8 -p X -l scratchpad.bin -k http://url_to_server/download/scratchpad.bin
OpenCL specific options:
-d N,N,N... - OpenCL devices to use (default: 0)
-i N - OpenCL work intensity (default: 18)
To mine on 2nd GPU only more intensive:
minerd -a wildkeccak_ocl -d 1 -i 22 ...
To mine on CPU (algorithm from original fork):
minerd -a wildkeccak ...
Run "minerd --help" to see all options.
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.

- To build a 64-bit binary,
export OBJECT_MODE=64
- GNU-style long options are not supported, but are accessible via configuration file
- Install MinGW and the MSYS Developer Tool Kit (http://www.mingw.org/)
- Make sure you have mstcpip.h in MinGW\include
- If using MinGW-w64, install pthreads-w64
- Install libcurl devel (http://curl.haxx.se/download.html)
- Make sure you have libcurl.m4 in MinGW\share\aclocal
- Make sure you have curl-config in MinGW\bin
- Install openssl devel (https://www.openssl.org/related/binaries.html)
- In the MSYS shell, run:
./autogen.sh # only needed if building from git repo
LIBCURL="-lcurldll" ./configure CFLAGS="-O3 *-march=native*"
# Use -march=native if building for a single machine
make
yum install mingw\*

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