+" in order to also check header files add this to your .vimrc:

+"   let g:syntastic_cuda_check_header = 1

+" By default, nvcc and thus syntastic, defaults to the most basic architecture.
+" This can produce false errors if the developer intends to compile for newer
+" hardware and use newer features, eg. double precision numbers. To pass a
+" specific target arch to nvcc, e.g. add the following to your .vimrc:
