With simple stand alone cmake 3.9 project using
cmake_minimum_required(VERSION 3.9)
project(cmake_testing CXX CUDA)
I can get a simple app to compile. It however fails to run with:
GPU Device 0: "GeForce GTX 960M" with compute capability 5.0
Current device is [0]
Current device is [0]
CUDA error at
C:\projects\cmake\cmaketesting\v3.9\cuda_basic\src\cuda_basic_test.cpp:67
code=46(cudaErrorDevicesUnavailable) "cudaMalloc((void **)&d_volume, size)"
When trying to call cudaMalloc. When trying to actually use the device.
checkCudaErrors(cudaMalloc((void **)&d_volume, size));
So I am right back I started in the new simple project.
I am able to complle and run SDK examples say nbody.
it can only be two things right??? compile args and runtime environment
(dll paths). right? err well or gremlins.
