I´m using vs2012 and CUDA 6.0, ever try all procedure cited for the microsoft in your official site:

between other cited in others sites, help-me please i´m desperate.

Note: the code is functional in c/c++, but when i´m using cuda 6.0, appears this problem. I´m desperate.

It’s been pointed out on your Stack Overflow posting that you have inconsistent definitions/usage of finalDataSet in your code, and this is the reason for the linker error. It seems that your statement “Note: the code is functional in c/c++, but when i´m using cuda 6.0, appears this problem.” could not possibly be correct.
