-----------------------------------
Assignee: Mark Harris
> ARROW_DEPRECATED warning when including io/interfaces.h from CUDA (.cu) source
> ------------------------------------------------------------------------------
>
> Key: ARROW-6205
> URL: https://issues.apache.org/jira/browse/ARROW-6205
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Affects Versions: 0.14.1
> Reporter: Mark Harris
> Assignee: Mark Harris
> Priority: Minor
> Labels: easyfix, pull-request-available
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> When including arrow/io/interfaces.h from a .cu source file (compiled with
> nvcc, the CUDA compiler), we get warnings like the following:
> {{[6/58] Building CUDA obje.../csv/csv_reader_impl.cu.}}
> {{arrow/install/include/arrow/io/interfaces.h(195): warning: attribute does
> not apply to any entity}}
> This example is from compiling [libcudf|[https://github.com/rapidsai/cudf].]
> libcudf installs these headers and includes them. This is a problem for
> libraries like libcudf which treat warnings as errors.
> There is a simple fix (I will submit a PR): change this code in interfaces.h:
> {{// TODO(kszucs): remove this after 0.13}}
> {{#ifndef _MSC_VER}}
> {{using WriteableFile ARROW_DEPRECATED("Use WritableFile") = WritableFile;}}
> {{using ReadableFileInterface ARROW_DEPRECATED("Use RandomAccessFile") =
> RandomAccessFile;}}
> {{#else}}{{// MSVC does not like using ARROW_DEPRECATED with using
> declarations}}{{using WriteableFile = WritableFile;}}
> {{using ReadableFileInterface = RandomAccessFile;}}
> {{#endif}}
>
> Just change the ifndef to:
> {{#if not defined(_MSC_VER) && not defined(__CUDACC__)}}
> This fix should have no impact on other compilers.
