Question

我正在尝试升级此项目（https://github.com/ashwin/gStar4D），该项目是用CUDA 4.0编写的8.0。但是我在Thrust上得到了大量的编译错误：

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

错误通常是'错误：类“推力:: tuple_size＆lt;＆gt;”没有成员“value”'，'错误：不允许不完整的类型'或'错误：名称后跟“::”必须是类或命名空间名称'
