Thrust error with thrust::copy during linking with CUDA 10.0

Accelerated Computing GPU-Accelerated Libraries

Hi,

I get an error when I copy a thrust::device_vector to a thrust::device_vector.

std::vector to thrust::device_vector works fine.
I have the feeling, It’s something with CUDA 10. I just made the jump from 7.5 to 10…

with thrust::device_vector val;

Matrix::Matrix(Matrix* M){

thrust::copy(M->val.begin(),M->val.end(),val.begin());

}

I get in the link stage:

I would really appreciate some help…

I don’t seem to have any trouble:

$ cat t309.cu
#include <thrust/device_vector.h>
#include <thrust/copy.h>

int main(){

  thrust::device_vector<int> v1(10);
  thrust::device_vector<int> v2(10);

  thrust::copy(v1.begin(), v1.end(), v2.begin());
}

You may want to provide a short, complete code/example that demonstrates the issue.
