             Summary: [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


See all the compiler warnings in our Windows builds

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
