This appears when tensor members operators are set a device in header

Problem appears by linking CUDA library.
Interaction.cu has tensor3 class and has no inconvenients to be linked.
BUT Subdomain.cu seems ti be the problem

Problem is in passing subdomain from HOST to DEVICE.
Subdomain is defined in host

__host__ void StartAcceleration(SubDomain &sd); // This is the buffer function which calls the kernel
__global__ void StartAccelerationKernel(SubDomain &sd);
