Gawain BOLTON commented on ARROW-7804:
--------------------------------------
It seems that clang versions < v3.9 have a bug regarding "const" and
"constexpr" as can be seen with the following two line code snipet:
{code:java}
struct EndRowType {};
constexpr EndRowType EndRow;{code}
The simplest change I have found is to replace "constexpr" with "extern const"
but this will require the implementation file to define the constant.
It is not clear to me which compiler versions must be supported so please let
me know if clang < v3.9 must indeed work with arrow >= v1.0.0
