> [C++] Compatibility macros for exported extern template class declarations
> --------------------------------------------------------------------------
>
> Key: ARROW-627
> URL: https://issues.apache.org/jira/browse/ARROW-627
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Reporter: Wes McKinney
> Assignee: Wes McKinney
> Priority: Major
> Fix For: 0.3.0
>
>
> See all the compiler warnings in our Windows builds
> https://ci.appveyor.com/project/ApacheSoftwareFoundation/arrow/build/1.0.652
> Also, consider the hacks we have around gcc/clang disagreement about
> visibility about the use of extern template:
> https://github.com/apache/arrow/blob/master/cpp/src/arrow/array.h#L508
> I suspect we may want some macros to help with compiler differences about
> such issues, possibly to go in
> https://github.com/apache/arrow/blob/master/cpp/src/arrow/util/visibility.h
