[I] [C++] Error linking the util/cancel.h [arrow]
tungdsefastec opened a new issue, #46258:
URL: https://github.com/apache/arrow/issues/46258
### Describe the usage question you have. Please include as many useful details as possible.
I tried to use arrow and parquet into c++ project. In the cmakefiles, the include directory is defined by **${CMAKE_SOURCE_DIR}/dependencies/apache-arrow/include**. The compiler is the MSVC 16.
The error I got is "dependencies\apache-arrow\include\arrow/util/cancel.h(109): error C2143: syntax error: missing ')' before 'public' "
### Component(s)
C++

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<rfl/parquet.hpp> :
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.

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.

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.

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 <iostream>
#include <QCoreApplication>
#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 <iostream>
#include "arrow/io/file.h"
#include <QCoreApplication>
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
std::cout << "nothing to show";
a.exec();
}

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

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