Unsupported gpu architecture 'compute_70' (mac os)

[twidlr]

Hello,

I'm trying to compile on Mac Os High Sierra 10.13.2 (17C88)
GPU: GTX 980 ti

Everything checks out except for Building NVCC

I used:

make install

and get:

nvcc fatal   : Unsupported gpu architecture 'compute_70'
CMake Error at xmrstak_cuda_backend_generated_cuda_extra.cu.o.Release.cmake:219 (message):
  Error generating
/CMakeFiles/xmrstak_cuda_backend.dir/xmrstak/backend/nvidia/nvcc_code/./xmrstak_cuda_backend_generated_cuda_extra.cu.o

Mining works but does only run on the CPUs

Does anyone know how to resolve this?

Thanks

Same issue here except compute_20 is not supported. Or sometimes the output will say make reference to libdevice sm_20, I think.

[psychocrypt]

Cuda 8 is not supporting 70 therefore the issue. @drew has the oposit issue in an other issue. He is using cuda9 where 20 is not supported. I am not sure but it looks like there is an osx cmake issue in the version check. Run ccmake and remove the 70 from CUDA_ARCH should solve your issue.

Thank you for your reply @psychocrypt

I checked my CUDA version, I have Cuda 9.0 installed

I will try you suggestions, and report if it works.

Cheers

I tried re-compiling

ran ccmake and removed the 70 from CUDA_ARCH

this time a get a different error related to CUDA:

Trying adding -DCUDA_COMPILER=clang to the cmake, this solved this issue for me.

@bmwbmerz8 using -DCUDA_COMPILER=clang:

[psychocrypt]

please empty the build directory after you switched from cuda 9 to cuda8.

[psychocrypt]

This bug should be solved with #532. Please report back if this fix is working for your case.
If you not familiar with git than you can download the branch for testing from https://github.com/psychocrypt/xmr-stak/archive/fix-CUDA9andOSCCompile.zip

@psychocrypt I tested your branch and am receiving the same problem using clang cmake . -DOPENSSL_ROOT_DIR=/usr/local/opt/openssl -DOpenCL_ENABLE=OFF -DCUDA_COMPILER=clang

The error is: clang: error: cannot find libdevice for sm_61. Provide path to different CUDA installation via --cuda-path, or pass -nocudalib to build without linking with libdevice.
