Hi, Dear Sir or Madam,
PS C:\plplot-5.15.0\build> gcc --version
gcc.exe (MinGW-W64 x86_64-ucrt-posix-seh, built by Brecht Sanders) 13.2.0

In my application, I used wxWidgets library and PLplot's wxwidgets binding: wxPLplotwindow.h.
I have successfully built PLplot library via CMake+MinGW64 compilers, but when using PLplot wxwidgets, the following errors occurred. Could someone help me with this problem?
I really need to fix these errors that occurred from PLplot's wxwidgets binding and then proceed to build my application. In my eyes there is nothing wrong in the plotwindow.h head file and please see the attached file for details. But GNU compiler generated such errors. It is very weird to me.
By the way, I downloaded it from the site: http://plplot.org/downloads.php. In my application, I need to have wxWidgets for GUI and PLplot for graph plotting, especially wxwidgets binding of PLplot library. I
I look forward to your help.
Thanks and Regards,
Dingjun
