Thanks. I got it. Qt defines `signals` macro as `public`. So the `signals` parameter name in https://github.com/apache/arrow/blob/272715f6df2a042d69881ffa03d5078c58e4b345/cpp/src/arrow/util/cancel.h#L112 is replaced to `public`. It causes the error because `public` is a C++ keyword. How to fix: Define `QT_NO_META_MACROS` before you include Qt. It prevents defining the `signals` macro. -- This is an automated message from the Apache Git Service.
