[jira] [Created] (ARROW-1159) [C++] Static data members cannot be accessed from inline functions in Arrow headers by thirdparty users

Wes McKinney created ARROW-1159:
-----------------------------------

             Summary: [C++] Static data members cannot be accessed from inline functions in Arrow headers by thirdparty users
                 Key: ARROW-1159
                 URL: https://issues.apache.org/jira/browse/ARROW-1159
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Wes McKinney
            Assignee: Wes McKinney
             Fix For: 0.5.0


This problem was exposed by the code migration in ARROW-1154. This yields DLL linking errors like

{code}
column_writer.cc.obj : error LNK2001: unresolved external symbol "private: static __int64 arrow::CpuInfo::hardware_flags_" (?hardware_flags_@CpuInfo@arrow@@0_JA)
statistics.cc.obj : error LNK2001: unresolved external symbol "private: static __int64 arrow::CpuInfo::hardware_flags_" (?hardware_flags_@CpuInfo@arrow@@0_JA)
{code}
