   For those who will encounter this error, here is how I fixed it for me when 
my Qt 6 project was giving me this error when trying to compile it with an 
added #include :
   When building and installing Arrow from source, I had installed Arrow into 
/usr/local, so I had to open it like this:
   sudo nano /usr/local/include/arrow/util/cancel.h
   Scroll down to the bottom and replace the name of the method paramer from 
"signals" to something else (I just added an underscore, so it became 
"_signals").
   Close and reopen QtCreator, open the project, compile. The problem is now 
gone.

   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.

   Could you generate pre-processed result by `-P -C` instead of `-c`?
   
   ```text

   This will generate `D:\1.Work\1.Code\untitled\main.i`.

   I used vcpkg for downloading the package. The version of the arrow is 
19.0.1. Actually, the MSVC 16 does support the C++17, and we are currently 
using C++ 17 for our project. We suspect that it conflicts with the 
qcoreapplication.h. I can build without errors if not including, or putting the 
arrow header before the qcoreapplication.h. 
   I made a simple example to check. 
   With this version, it will give error.
   #include 
   #include 
   #include "arrow/io/file.h"
   int main(int argc, char *argv[])
   {
   QCoreApplication a(argc, argv);
   std::cout << "nothing to show";
   a.exec();
   }
   
   However, if I put the "arrow/io/file.h" before the QCoreApplication, it will 
be fine.
   #include 
   #include "arrow/io/file.h"
   #include 
   int main(int argc, char *argv[])
   {
   QCoreApplication a(argc, argv);
   std::cout << "nothing to show";
   a.exec();
   }

   Could you give more details on how are you building Arrow? How are you 
downloading it? What version of Arrow are you using? From my understanding MSVC 
16 is out of support and uses C++14 as its standard, C++ 17 has been required 
for Arrow for the last 2.5 years (https://github.com/apache/arrow/pull/13991) 
but I am unsure if that's the issue without more details.
