             Summary: [C++] Thrift-generated symbols not exported in DLL
                 Key: PARQUET-1420
                 URL: https://issues.apache.org/jira/browse/PARQUET-1420
             Project: Parquet
          Issue Type: Bug
          Components: parquet-cpp
            Reporter: Antoine Pitrou


Thirft-generated symbols don't have any {{PARQUET_EXPORT}}-like annotation, so they are not reachable from the Parquet DLL. In turn this makes it impossible to link Parquet unit tests with the Parquet DLL (instead of the Parquet static lib). I'm not sure it can impact other applications.

Example linking error:
{code}
column_writer-test.cc.obj : error LNK2019: unresolved external symbol "public: v
irtual unsigned int __cdecl parquet::format::Statistics::read(class apache::thri
ft::protocol::TProtocol *)" (?read@Statistics@format@parquet@@UEAAIPEAVTProtocol
@protocol@thrift@apache@@@Z) referenced in function "[thunk]:public: virtual uns
igned int __cdecl parquet::format::Statistics::read`vtordisp{4294967292,0}' (cla
ss apache::thrift::protocol::TProtocol *)" (?read@Statistics@format@parquet@@$4P
PPPPPPM@A@EAAIPEAVTProtocol@protocol@thrift@apache@@@Z)
