Hi Everyone,

I’m hoping someone can shed some light on an error I am receiving from cudafe.exe - it crashes and I get a

"1>cuda_code.cu(70): internal error: can’t generate code for non empty constructors or destructors on device

1>1 catastrophic error detected in the compilation of “C:\Users\SEBAST~1\AppData\Local\Temp/tmpxft_0000096c_00000000-6_cuda_code.cpp1.ii”." error.

```

```

Ok, thats my code above. I’m creating a camera in const memory using this:

```
__constant__ Camera cam;
```

That’s when the error is generated. Why is there a problem with have my Point3D structs within my Camera struct? I removed the structs so that the only members were floats and it compiled fine. Please, someone help me!
