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
This repo is intended to have valid source code to build the miner on macOS, why?
- Because it's my primary platform
- So that I can mine in all computers in the Apple Store (sarcasm)
- Because I probably have too much free time
Releases have only the xmr-stak binary and it's proper config file, they also submit 1% shares to me (sorry fierce-uk). If you like this or if it's useful to you please consider mining at my pool.
If you can't/don't want to install the dependencies (like when you're not an administrator), just use the binary under xmr-stak-nohttp-nossl/ folder in releases, else read below.
- Install brew
- Install openssl and libmicrohttpd,
brew install openssl libmicrohttpd
- Run the binary in Terminal app
You should have Xcode installed, or Command-line tools (just do xcode-select --install
in the Terminal App)
brew install libmicrohttpd openssl cmake
cmake .
make
the miner binary will be under bin/ folder.
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.
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)
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

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 :
-
Download and install Windows Server 2003 Resource Kit Tools. Ignore incompatiablity warning during installation.
-
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) -
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).
The build system is CMake, if you are not familiar with CMake you can learn more here.
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 thang
(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
- enable a option:
After the configuration you need to call
make install
for slow sequential build
or
make -j install
for faster parallel build
and install.
CMAKE_INSTALL_PREFIX
install miner to the home foldercmake . -DCMAKE_INSTALL_PREFIX=$HOME/xmr-stak-cpu
- you can find the binary and the
config.txt
file aftermake install
in$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
orDebug
- you should always keep
Release
for your productive miners
- disable with
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_REQUIRED
allow 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
