CUDA include file errata?

Accelerated Computing CUDA CUDA Programming and Performance

I tried to compile code with this union

union PrecomputedBlob

{

  struct

  {

  uint8_t

	minX, minY, maxX, maxY,

	perimeter, area,

	vertices, edges,

	sumX, sumY,

	sumX2, sumY2, sumXY;

  };

  uint4 v;

};

It compiles fine, but when compiling for emulation mode, the host compiler (not NVCC) complains that the union is illegal

because uint4 has a non-trivial assignment operator, which is against the C++ standard. This problem goes away when I remove the

line __cuda_assign_operators(uint4) from vector_types.h.

What’s the purpose of __cuda_assign_operators and can this be resolved in the future?

Probably won’t be resolved: [url=“http://forums.nvidia.com/index.php?showtopic=157282”]http://forums.nvidia.com/index.php?showtopic=157282[/url]
