MSBuild error on Building cpp-ethereum

I'm trying to follow the API guide to setup ethminer, but for some reason I keep getting an error when attempting to build the c++ ethereum mining software. The guide I'm trying to follow is: http://www.ethdocs.org/en/latest/ethereum-clients/cpp-ethereum/building-from-source/windows.html
It reads as follows:
C:\Windows\System32\cpp-ethereum\build> cmake -G "Visual Studio 14 2015 Win64" .. CMAKE Error at CMakeLists.txt:44 (project): Failed to run MSBuild command: C:/Program Files (x86)/MSBuild/14.0/bin/MSBuild.exe to get the value of VCTargetsPath: Microsoft (R) Build ENgine version 14.0.25420.1 Copyright (C) Microsoft Corporation. All rights reserved. MSBUILD : error MSB1009: Project file does not exist. Switch: VCTargetsPath.vcxproj Exit code: 1 -- Configuring incomplete, errors occurred! See also "C:/Windows/System32/cpp-ethereum/build/CMakeFiles/CMakeOutput.log". 
The afformentioned log only has this:
The system is: Windows - 10.0.15063 - AMD64 
I have VS2015 installed as well as cmake and git, I'm not sure what I'm doing wrong. Does anyone know what I can do to get around this problem? Thanks!
Included in the build directory is a CMakeCache.txt, which seems to hold the settings for the build, and reads as follow:
# This is the CMakeCache file. # For build in directory: c:/Windows/System32/cpp-ethereum/build # It was generated by CMake: C:/Program Files/CMake/bin/cmake.exe # You can edit this file to change values found and used by cmake. # If you do not want to change any of the values, simply exit the editor. # If you do want to change a value, simply edit, save, and exit the editor. # The syntax for the file is as follows: # KEY:TYPE=VALUE # KEY is the name of a variable in the cache. # TYPE is a hint to GUIs for the type of VALUE, DO NOT EDIT TYPE!. # VALUE is the current value for the KEY. ######################## # EXTERNAL cache entries ######################## //Semicolon separated list of supported configuration types, only // supports Debug, Release, MinSizeRel, and RelWithDebInfo, anything // else will be ignored.

Other than that there really isn't much else... no error logs as far as I can see either

EthereumJ vs. cpp-ethereum

I'm designing a private Ethereum blockchain. Now, I'm choosing which technology is suitable for the project. My customer has concerns with GPLs licenses and I reach this 2 projects which have MIT license. Does anyone use them? I would like to know your experience with them and recommendations.

Why is cpp-ethereum now calling their projects webthree?

For instance webthree-umbrella (which includes web3.js as a module): https://github.com/ethereum/webthree-umbrella
Or webthree, which provides eth: https://github.com/ethereum/webthree/tree/develop
Or libwebthreecore, which provides C++ Ethereum "stuff": https://github.com/ethereum/libweb3core/tree/develop
If you look at commit histories, it would seem that the original cpp-ethereum repository is being moved to ones titled "webthree".
This is causing immense confusion for some developers as well as for projects that rely on this code. For instance, the correct answer for "Where can I find the most up to date Solidity compiler?" is no longer obvious -- not to mention that the broad changes made to Solidity, for those that receive versions not available in the cpp-ethereum repository, are causing cascading issues.
That said, the name change is confusing. For instance: Is web3 (aka "webthree") more than just the javascript library for interacting with Ethereum? Does "webthree" now include both the Ethereum library as well as the cpp-ethereum client (but not pyethereum, go-ethereum, ethereumjs, etc.)? If so, why? What's the point of merging these names, which to me are very distinct projects, all under the Ethereum umbrella?
Would love your thoughts. Cheers.
Edit: A word. And this edit update.

Cpp-Ethereum for OSX install help pls!

Could someone that has successfully installed Cpp-Ethereum on OSX with GPU mining please post a step by step of exactly the install path you took.

Why is cpp-ethereum GPL and pyethereum MIT?

Why is there a difference between the two licenses when they provide the same functionality? I'd be more inclined to use python since it's MIT.

Crashes with cpp-ethereum

Hey, so I've been mining for the past two weeks almost with no problems. I am using cpp-ethereum and I haven't encountered any problems until today. I went ahead and launched cmd, changed the directory so it could find the executable file, and ran the command line to start the process. But after 3 lines, it crashed. Do you know what could possibly be causing this and how to fix it? Thanks for your help Edit: Thanks for trying to help guys but I fixed it. Just had to delete the dag files in Ethash folder

new version of cpp-ethereum / mix / solidity

We just released version 1.2.4 of cpp-ethereum including version 1.0.3 of mix and version 0.3.2 of solidity.
In this release we mainly focused on the build system and changes not visible to the end-user. The aim is to decouple the various binaries so that they can be built in isolation. For Solidity, some quite important bugs were fixed, so please upgrade.
Important: The Mix binary was renamed to mix-ide in order to avoid name conflicts with elixir's build tool.
eth (1.2.4):
solidity (0.3.2):
mix (1.0.3):

Why it is impossible to verify contracts compiled with solc from cpp-ethereum (It is the most frequently updated binary version for Windows).

The newest binary version of solc for windows I could find is one available in cpp-ethereum release. I compiled a contract with it (the version of solc is 0.3.5-5f97274a/RelWithDebInfo-Windows/msvc/Interpreter, but this version is not available on Etherscan to verify a contract with :(. Can it be made available? Or is there any other binary version that can be easily downloaded that is on Etherscan?

Ethereum code optimized for some nvidian cards davilizhdavilizh Posts: 1Member ✭

The code is optimized for GTX1060, can improve GTX1060 with 2 GPC performance by 15%, and GTX1060 with 1 GPC performance by more than 30%. Meanwhile, it also increases performance on GTX1070 by 3%, on Telsla M60 by 2%, and should also benefit other chips.
When executing the code, please do remember to add "-U" to your argument. Two locations to download the code:
  1. https://github.com/Genoil/cpp-ethereum/pull/228
  2. https://github.com/ethereum-mining/ethminepull/18
  3. Windows exe download: https://ci.appveyor.com/project/ethereum-mining/ethminebuild/93/job/ss7k95dsy1kly4vl/artifacts
If you have any concerns about the code, don't hesitate to comment or send email to me.
Some detailed information about the optimization:
  1. ethash_cuda_miner_kernel.cu I have commented out "launch_bounds" in the code. launch_bound is discussed in http://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#axzz4fzSzZc9p in detail.
  2. dagger_shuffle.cuh 1) We moved around and reduced variable definitions to the minimum required. The compiler should have been able to do this analysis, but it never hurts to help out the compiler. The state in compute_hash of dagger_shuffle.cuh is modified. 2) We simplify the nested if/else blocks into a switch statement. 3) We simplify control flow. Remove the conditional from the inner loop so all threads calculate the value, and then all threads use a __shfl to read thread t's value (throwing away the rest of the threads' calculated value). 4) We increase the total number of LDGs to increase occupancy. We define PARALLEL_HASH to let each warp have PARALLEL_HASH LDGs in-flight at a time, not 1 at a time, which is the original case.
  3. keccak.cuh Since the input argument uint2 *s is changed in dagger_shuffle.cuh, we have to modify keccak_f1600_init and keccak_f1600_final in keccak.cuh accordingly.
