NOTE: This forked repository contains a VS2015 solution and Win32 build of libmicrohttpd library required to build xmr-stak-cpu on Windows. xmr-stak-cpu project is retired - you should upgrade to xmr-stak.

XMR-Stak-CPU - Monero mining software

XMR-Stak is a universal Stratum pool miner. This is the CPU-mining version; there is also an AMD GPU version and an NVIDA GPU version

HTML reports

Usage on Windows

1. Edit the config.txt file to enter your pool login and password.
2. Double click the exe file.

XMR-Stak should compile on any C++11 compliant compiler. Windows compiler is assumed to be MSVC 2015 CE. MSVC build environment is not vendored.

Compile on Linux (Debian-based distros)

GNU Compiler

    sudo apt-get install libmicrohttpd-dev libssl-dev cmake build-essential
    cmake .
    make install

• GCC version 5.1 or higher is required for full C++11 support. CMake release compile scripts, as well as CodeBlocks build environment for debug builds is included.

To do a static build for a system without gcc 5.1+

    cmake -DCMAKE_LINK_STATIC=ON .
    make install

Note - cmake caches variables, so if you want to do a dynamic build later you need to specify '-DCMAKE_BUILD_TYPE=RELEASE'

You can find a complete compile guide under Advanced Compile Options.

CPU mining performance

Performance is nearly identical to the closed source paid miners. Here are some numbers:

• I7-2600K - 266 H/s
• I7-6700 - 276 H/s (with a separate GPU miner)
• Dual X5650 - 466 H/s (depends on NUMA)
• Dual E5640 - 365 H/s (same as above)

Default dev donation

By default the miner will donate 1% of the hashpower (1 minute in 100 minutes) to my pool. If you want to change that, edit donate-level.h before you build the binaries.

If you want to donate directly to support further development, here is my wallet

Common Issues

SeLockMemoryPrivilege failed

Please see config.txt under section LARGE PAGE SUPPORT

For Windows 7 pro, or Windows 8 and above see this article (make sure to reboot afterwards!).

For Windows 7 Home :

1. Download and install Windows Server 2003 Resource Kit Tools. Ignore incompatiablity warning during installation.

2. In cmd or power shell: ntrights -u %USERNAME% +r SeLockMemoryPrivilege (where %USERNAME% is the user that will be running the program. This command needs to be run as admin)

3. Reboot.

Reference: http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?pid=259791#pid259791

Warning: do not download ntrights.exe from any other site other then the offical Microsoft download page.

VirtualAlloc failed

If you set up the user rights properly (see above), and your system has 4-8GB of RAM (50%+ use), there is a significant chance that there simply won't be a large enough chunk of contiguous memory because Windows is fairly bad at mitigating memory fragmentation.

If that happens, disable all auto-staring applications and run the miner after a reboot.

msvcp140.dll and vcruntime140.dll not available errors

Download and install this runtime package from Microsoft. Warning: Do NOT use "missing dll" sites - dll's are exe files with another name, and it is a fairly safe bet that any dll on a shady site like that will be trojaned. Please download offical runtimes from Microsoft above.

Error: MEMORY ALLOC FAILED: mmap failed

From config.txt:

On Linux you will need to configure large page support sudo sysctl -w vm.nr_hugepages=128 and increase your ulimit -l. To do do this you need to add following lines to /etc/security/limits.conf:

* soft memlock 262144
* hard memlock 262144

Save file. You WILL need to log out and log back in for these settings to take affect on your user (no need to reboot, just relogin in your session).

You can also do it Windows-style and simply run-as-root, but this is NOT recommended for security reasons.

Illegal instruction (core dumped)

This typically means you are trying to run it on a CPU that does not have AES. This only happens on older version of miner, new version gives better error message (but still wont' work since your CPU doesn't support the required instructions).

Advanced Compile Options

The build system is CMake, if you are not familiar with CMake you can learn more here.

Short Description

There are two easy ways to set variables for cmake to configure xmr-stak-cpu

• use the ncurses GUI
  • ccmake .
  • edit your options
  • end the GUI by pressing the key c(create) and than g(generate)
• set Options on the command line
  • enable a option: cmake . -DNAME_OF_THE_OPTION=ON
  • disable a option cmake . -DNAME_OF_THE_OPTION=OFF
  • set a value cmake . -DNAME_OF_THE_OPTION=value

After the configuration you need to call make install for slow sequential build or make -j install for faster parallel build and install.

xmr-stak-cpu Compile Options

• CMAKE_INSTALL_PREFIX install miner to the home folder
  • cmake . -DCMAKE_INSTALL_PREFIX=$HOME/xmr-stak-cpu
  • you can find the binary and the config.txt file after make install in $HOME/xmr-stak-cpu/bin
• CMAKE_LINK_STATIC link libgcc and libstdc++ libraries static (default OFF)
  • disable with cmake . -DCMAKE_LINK_STATIC=ON -CMAKE_BUILD_TYPE set the build type
  • valid options: Release or Debug
  • you should always keep Release for your productive miners
• MICROHTTPD_REQUIRED allow to disable/enable the dependency microhttpd
  • by default enabled
  • there is no http interface available if option is disabled: cmake . -DMICROHTTPD_REQUIRED=OFF
• OpenSSL_REQUIREDallow to disable/enable the dependency OpenSSL
  • by default enabled
  • it is not possible to connect to a https secured pool if optin is disabled: cmake . -DOpenSSL_REQUIRED=OFF
