Summary: Hdfs and java dlls fail to load when built for Windows with MSVC Key: ARROW-1003 URL: https://issues.apache.org/jira/browse/ARROW-1003 Project: Apache Arrow Issue Type: Bug Components: C++ Environment: Windows, MSVC Reporter: Balázs Gosztonyi If I build the cpp library with MSVC for windows and try to use the hdfs io interface, the dynamic library loads fail. The reason is that in file hdfs-internal.cc on two occasions the __WIN32 define is checked instead of _WIN32. The former is not set by MSVC. I checked that these are the only two locations in the arrow library where the flag __WIN32 is used, so all we need to do is replace these two references in hdfs-internal.cc. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
