Thrust errors upgrading from CUDA 4.0 to 8.0

Question

I am attempting to upgrade this project (https://github.com/ashwin/gStar4D), which is written in CUDA 4.0 to 8.0. But I am getting a ton of compile errors from Thrust on lines like this:

    thrust::sort_by_key(    orderVec.begin(), orderVec.end(),
                            thrust::make_zip_iterator( make_tuple( _pointVec->begin(), _scaledVec->begin() ) ) );

The errors are typically 'error : class "thrust::tuple_size<>" has no member "value"', 'error : incomplete type is not allowed' or 'error : name followed by "::" must be a class or namespace name'

Any thoughts on what the issue could be?

Answer 1

As Robert suggested above, just needed to add thrust:: to make_tuple:

thrust::sort_by_key(    orderVec.begin(), orderVec.end(),
                        thrust::make_zip_iterator( thrust::make_tuple( _pointVec->begin(), _scaledVec->begin() ) ) );

Just submitted a PR with all the changes necessary to run on Cuda 8.0 here: https://github.com/ashwin/gStar4D/pull/1
