Hello,

GPU: nvidia geforce gtx 1650 ti OS: Ubuntu 20.04

• I struggled to compile libxmrig-cuda.so because I got messages like this:

; Valid CUDA Toolkit Map: ; 8.x for Fermi/Kepler /Maxwell/Pascal, ; 9.x for Kepler /Maxwell/Pascal/Volta, ; 10.x for Kepler /Maxwell/Pascal/Volta/Turing, ; 11.x for Kepler (in part)/Maxwell/Pascal/Volta/Turing/Ampere

;Reference https://developer.nvidia.com/cuda-gpus#compute for arch and family name

CMake Error at cmake/CUDA.cmake:71 (message): Unsupported CUDA architecture '30' specified. Use CUDA v10.x maximum, Kepler (30) was dropped at v11. Call Stack (most recent call first): CMakeLists.txt:81 (include)

-- Configuring incomplete, errors occurred! See also "/home/edelcastillo/bin/xmrig-cuda/build/CMakeFiles/CMakeOutput.log".

• I had to do that: $ cmake .. -DCUDA_LIB=/usr/local/cuda/lib64/stubs/libcuda.so -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda -DCUDA_ARCH=50

Anybody has any idea?

Thanks in advance

Your GPU is CUDA Capability 7.5

So build it with -DCUDA_ARCH=75
