Ethminer: nvcc fatal : Unsupported gpu architecture 'compute_70'

[phalexo]

CMake Error at ethash-cuda_generated_ethash_cuda_miner_kernel.cu.o.Release.cmake:222 (message):
Error generating
/home/miner/ethminer/build/libethash-cuda/CMakeFiles/ethash-cuda.dir//./ethash-cuda_generated_ethash_cuda_miner_kernel.cu.o

Compute 70 is for newer architecture, and I don't have those. Makefile should not be generating stuff that is not compatible with my GPUs, i.e. older Titax X.

just update cuda to cuda 9.0...
We have to support ever architecture, you can easily modify the makefile yourself.
It's here. libethash-cuda/CMakeLists.txt

Nvidia does not offer that version for Ubuntu 14.04 LTS.

as @MariusVanDerWijden mentioned, just edit libethash-cuda/CMakeLists.txt and remove the compute_70 line.

You also can use a prebuild version from here: https://github.com/ethereum-mining/ethminer/releases

The file doesn't exist for me. Only these files exist:

$ ls libethash-cuda/
CMakeFiles          Makefile            cmake_install.cmake

$ ls libethash-cuda/
CMakeFiles          Makefile            cmake_install.cmake

Try this command:

$ git pull origin master

Or if you downloaded, delete and download again.
