Compile xmr-stak-rx for Linux

Install Dependencies

AMD Driver (only needed to use AMD GPUs)

• the AMD APP SDK is not longer needed (all is included in the driver package)
• download & unzip the AMD driver: https://www.amd.com/en/support
• run ./amdgpu-pro-install --opencl=legacy,pal from the unzipped folder
• set the environment variable to opencl export AMDAPPSDKROOT=/opt/amdgpu-pro/

For linux also the OpenSource driver ROCm 1.9.X+ is a well working alternative, see https://rocm.github.io/ROCmInstall.html ROCm is not supporting old GPUs please check if your GPU is supported https://rocm.github.io/hardware.html.

Cuda 8.0+ (only needed to use NVIDIA GPUs)

• download and install https://developer.nvidia.com/cuda-downloads
• for minimal install choose Custom installation options during the install and select
  • CUDA/Develpment
  • CUDA/Runtime
  • Driver components

GNU Compiler

    # Ubuntu / Debian
    sudo apt install libmicrohttpd-dev libssl-dev cmake build-essential libhwloc-dev ocl-icd-opencl-dev
    git clone https://github.com/fbmoose48/xmr-stak.git -b xmr-stak-rx
    mkdir xmr-stak/build
    cd xmr-stak/build
    cmake ..
    make install

    # Arch
    sudo pacman -S --needed base-devel hwloc openssl cmake libmicrohttpd
    git clone https://github.com/fbmoose48/xmr-stak.git -b xmr-stak-rx
    mkdir xmr-stak/build
    cd xmr-stak/build
    cmake ..
    make install

• g++ version 5.1 or higher is required for full C++11 support.

• Some newer gcc versions are not supported by CUDA (e.g. Ubuntu 17.10). It will require installing gcc 5 but you can avoid changing defaults.

In that case you can force CUDA to use an older compiler in the following way:

cmake -DCUDA_HOST_COMPILER=/usr/bin/gcc-5 ..

• You need 1 Gb RAM to compile (a bit less might be enough, 512 Mb isn't).

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

    cmake -DCMAKE_LINK_STATIC=ON -DXMR-STAK_COMPILE=generic .
    make install

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

Turn off the web server that uses httpd in cmake with

cmake -DMICROHTTPD_ENABLE=OFF .. Then build as usual make -jN install

Compile Xmr-Stak-RX for FreeBSD

Install Dependencies

Note: This guide is tested for FreeBSD 11.0-RELEASE

From the root shell, run the following commands:

pkg install git libmicrohttpd hwloc cmake

Type 'y' and hit enter to proceed with installing the packages.

git clone https://github.com/fbmoose48/xmr-stak.git -b xmr-stak-rx
mkdir xmr-stak/build
cd xmr-stak/build
cmake ..
make install

Now you have the binary located at "bin/" and the needed shared libraries.
