5 years ago Please, help me to build, compile and run xmr-stak-cpu from VS2017 for working on CPU, not GPU. Where to write not to demand CUDA, for example? In .md files you wrote how to build, compile and run only for GPU-s. Please, write in details, how to do it.

5 years ago This is the command: cmake -G "Visual Studio 15 2017 Win64" -T v140,host=x64 -DXMR-STAK_CURRENCY=monero -DCMAKE_BUILD_TYPE=DEBUG -DXMR_STAK_COMPILE=generic -DCUDA_ENABLE=ON -DCUDA_ARCH=61 DOpenSSL_ENABLE=OFF ..
And the output is: Warnings: 0 Errors: 1 Time passed: 00:00:00.34 Exit code: 1 --Configuring incomplete, errors occured! See also "../../build/CMakeFiles/CMakeOutput.log"
And CMakeOutput.log: The system is: Windows - 10.0.17134 - AMD64

5 years ago and before the error there was no output? I missed all output where cmake search the dependancies. Please use always a new build folder. Also post the command you used to load visual studio.
Please send alwas ALL output and not only the error

5 years ago please also remove the currency from the cmake string this is no option. Debug is case sensitive and must be "Debug"

5 years ago The problem was in version. I wrote v141 and build was made. But in Visual studio 8 errors appeared: C1047 in libhwloc.lib, LNK2001 in xmr_opencl_backend and in xmr_stak_cuda_backend in SSL_CTX_set_options and in TLS_method of this projects. Also LNK1120 in xmr_opencl_backend and in xmr_cuda_backend And LNK1257 in xmr_stak

5 years ago And details about errors: LINK2001: unresolved external symbol TLS_method. This error appears both in xmr_stak_cuda_backend and in xmr_opencl_backend. LINK2001: unresolved external symbol SSL_CTX_set_options. This error appears both in xmr_stak_cuda_backend and in xmr_opencl_backend. С1047: ....\xmr-stak-dep\hwloc\lib\libhwloc.lib was created with an older compiler than other objects; rebuild old objects and libraries

5 years ago BUILD_ALL has been made normally. I used v3 of xmr-stak-dep. But another problem appeared: it can't be run even from VS2017 15.9.3. Visual Studio writes: "Unable to start program. I:\Projects\Monero\xmr-stak-2.6.0\build\x64\Debug\ALL_BUILD. Access denied." But it normally runs if I simply execute xmr-stak.exe from Total Commander. Antivirus service has been stopped.

5 years ago Toolset directory for version '14.11' was not found. says that you have not installed the toolchain 14.11. you can add it any time to your cisuals tudio. sometimes the option to add a second toolchain is a little bit hidden behind some advanced option. Check google for a how to to install two toolchains for VS.

5 years ago so i opened "ALL_BUILD.vcxproj" in vs. Duckduck-go-ed a bit. Appears i had to go to (menu)Build>Configuration manager. Set the first dropdown to release, close manager window And then (menu)Build>Build all. Wich creates the .exe in "C:\Map\xmr-stak-2.7.0\bin\Release". So i finally build it. Forgot something tho. Since i'm trying to learn to compile this for a HPC cluster, i enabled OpenSSL. Wich wasnt present yet. Now it cant find the OpenSSl.dll and i dunno howto configure OpenSSL yet. Also useless to do so, cuzthis win isnt part of the linux HPC. My q; i have to re-do the whole story, but with OpenSSlEnabled=OFF?(on the win im using to tinker) Tip to author; wordpress tutorial with forum for xmr-stak, and mine with visitors/readers CPU. Wether they volunteer a contribution or not, compile with donation set to zero, as long as they use ure online edu materials, they r contributing.

5 years ago [b]pekster85,[/b] you need to open ,sln file in VS at first. Then you should open Solution properties (right mouse button click on your solution)->Startup Project. Then choose "Multiple startup projects:" Set "start" on xmr-stak and None - to other projects.

5 years ago I have never opened anything in VS.
@pekster85 seems you didn't make a build subdirectory but instead used cmake . from the source root? This will spew files all over the place, you are required to use mkdir ./build && cd ./build && cmake .. for the compiled files and intermediates to be ignored by Git.

OK, first off, ure instructions are incomplete my smart tinker friend. Highly appreciate the effort, But, without pre-existing knowledge, or help from users here, ure screwed. Literally try it on a clean WIN. Wont work.(5x:did laptop+quadcore+8core+2sorry excuses of pc's). One HAS to switch from CMD to involve CMAKE gui, preset and press configure, the CMAKE CMD build command doesnt work, so one HAS to open VS. One HAS to select the project,put it from debug to release, and BUILD. cuz ure cmd instructions wont. Dont get me worng, i apreciate the effort, i learned alot. But it took a couple expeditions. also tried the other (cuda) on another 2 pc's, wich wont work because it cant find CUDA(yes other dep zip). and only experienced users know how to include CUDA s location to the equiasion. upto now, not one openCL or AMD has succeeded. only CPU. wich is fine for me, but still, i have 2xgtx260 cards lying around catching dust... would be a pity. Spudz 76, u missed a part. mkdir was done before. nevermind.

5 years ago pekster85, I simply installed CUDA 10.0 from its oficial site, and it has been included automatically to the environment variable "PATH". But another problem appeared: XMR-STAK doesn't mine on GPU. If CPU is included, it(xmr-stak) switches to CPU, if CPU isn't included, it(xmr-stak) simply collects works from the pool and doesn't do anything with them. But the hashrate of both CPU and GPU is being calculated. GPU is NVIDIA 1050 GTX. If you try to debug xmr-stak, you'll see that xmrstak_cuda_backend will have never used (you may insert breakpoint in any line of cuda_core.cu and you'll see that it can't be achieved).

5 years ago @vasilevskykv , "and it has been included automatically to the environment variable "PATH". " weird, i tried 5 times."CUDA could not be found, no such path or directory" and i downed v10 too. "XMR-STAK doesn't mine on GPU" that does not seem to be the authors intention... Seems to me that CUDA libraries are required to enable communication between amd driver and XMR stak. But i'll have to read a TON of code lines before its gonna make sense... Did YOU try the precompiled Version? cuz thats my next step to check. test prebuild exe, test GPU only, try mining. one has 10yr old gtx260's, but they r wasted right now, so i get to learn and tinker, and repurpose dust-collectors ...

5 years ago I tried the precompiled version. It is aslo being switched to CPU, though hashrate of GPU is being calculated

5 years ago It seems to me - I found my problem. CUDA can't be fully integrated to Visual Studio 2017 and NSight can't debug. I tried to make the type of files .cu - CUDA C/C++. Visual Studio didn't showed me such type. And NSight debugger dosen't see my breakpoints in .cu files.

5 years ago If you refer to the (upstream) CMake documentation, the files it generates are not really meant to work in the IDE. They are for the MSBuild non-GUI tools to consume and output either a Debug or Release build.
I have never heard of opening the resulting project and attempting to do anything that way. If you don't like how it builds, edit the CMakeLists.txt
For a development IDE, use CLion or something.
What you are trying to do is literally unsupported, may be why it won't work?
pekster85
commented
5 years ago @Spudz76 (1) who r u replying to? (2) why do you think we're trying Alternative approach? (3) "edit the CMakeLists.txt" ok. how? with what, and why.
(4) since the RTX series of graphics cards came out, suitable mining cards come available secondhand at fraction of their original price. Both Nvidia AND AMD. NO GRAPHICS CARD MINES on the PRECOMPILED stak. Now i'm no programmer, no Linux guru, just a guy who reads and follows instructions. And i'm telling you, THESE INSTRUCTIONS r INCOMPLETE.
As a contibutor, one might expect a word of explanation,
cuz stating
"What you are trying to do is literally unsupported, may be why it won't work?"
doesnt help anyone.

5 years ago (1) @vasilevskykv probably, considering those were the most recent three posts here, and it's their thread to begin with
(2) Stuff about opening the vcxproj file... what, why?
(3) For whatever it is you're trying to do, which is unclear, other than compile this project which has nothing to do with looking at any of the build files CMake generated, and especially not opening them in Visual Studio or attempting to build from the IDE. If CMake didn't build the EXE/DLL outputs then you've not set up your environment (PATH, INCLUDE, LIB... among others) correctly, or you're doing CMake wrong.
(4) Release binaries support anything supported by CUDA 10.0 (driver 4xx.xx or newer), and anything AMD provided you've also not installed the wrong drivers, all work with the precompiled. Anything dropped from CUDA 10.0 is no longer supported in the precompiled releases, but work fine given CUDA 8 SDK and your own compilation. There is not much reason to bother with any of the 9.x versions now, either.
(5) Yes releases used to be compiled for CUDA8 for a long long time, now it isn't. Holding everything else back to v140 toolkit was no longer worth it, and the new PoW math works pretty bad on Fermi anyway, so the release was bumped to CUDA 10.0 SDK. CUDA 8 app also does not work best when running 9.1/9.2/10.0 level drivers, for all other cards than Fermi. If you feel the need to be angry at someone, it'd be nVidia for dropping Fermi support before people were done using them, I guess.

5 years ago I lost the focus in this discussion. Is there still an open issue. Note: The compile instructions work if the environment finds cmake and you use the latest dependancy package with e.g. cuda 10 and the latest visual studio. I create the binaries with this combination for Cuda10 and 9. For AMD you can use the old AMD APP Sdk or better the OpenCLlight SDK (see the docu). The precompiled binaries for windows supports all NVIDIA devices from 3.0 to 7.X (turing).

5 years ago I tried to make build for AMD. I installed drivers for AMD. But it can't find OpenCL . I don't understand how to install OpenCL for Windows 10. It seems to me that it can work only for Linux. I saw open64 sdk-s only for linux type systems

5 years ago @Spudz76 @psychocrypt The issue is: neither @vasilevskykv or me, cant get ANY GPU miner to work. I'm trying Nvidia, seems @vasilevskykv is trying AMD. Neither the precompiled stak, nor the to-be-compiled stak, seem to find what they require. i've tried the precompiled, tried compiling on 5PC's. And i'm telling you, again, something in ure guide is off. first: "For CUDA 8 execute: cmake -G "Visual Studio 15 2017 Win64" -T v140,host=x64 .. For CUDA 9 and/or AMD GPUs, CPU execute: cmake -G "Visual Studio 15 2017 Win64" -T v141,host=x64 .." Never works. It never finds what it needs, allthough all instrucions were followed and all named neccassary components were aquired. second; "cmake --build . --config Release --target install" does NEVER work. one HAS to open VS. put the build in release, and build. cuz otherwise, nothing happens. note: my cmake cmd/gui has NEVER been able to build,(always errors) yet VS does it in 30sec.
