I'm trying to build ethminer on a windows box and am Visual Studio 2015 fails. The steps that I take are the following:

Download ethminer/cpp-ethereum and install dependencies using the command line prompt with Administrator privileges:

git clone https://github.com/Genoil/cpp-ethereum.git
cd extdep
getstuff.bat

So far, so good, now I create (I've struggled a bit with CMake) the Visual Studio 2015 project solution files using CMake:

mkdir build
cd build
cmake.exe -DBUNDLE=cudaminer -G "Visual Studio 14 2015 Win64" ..

Everything seems okay (the solution files are generated) but when I try to build from VS I get a large number of errors:

Severity    Code    Description Project File    Line    Suppression State

Also, I can't seem to find the compiler configuration details (it seems like the CXX compiler is not being used).

  • I'm having the exact same problem. Did you ever find a solution for this?

  • Yes, use an earlier version of Visual Studio.

    I was able to get it to compile under vs2015 by switching all the projects to the "Visual Studio 2013 (v120)" toolset (project / properties).
