I am using wxWidgets to build a GUI application using Eclipse CDT (GNU C++)

  • 0

I am using wxWidgets to build a GUI application using Eclipse CDT (GNU C++) under Fedora Linux. The program compiles and runs fine, but in the Eclipse “problems” tab, there are so many “semantic errors” and “code analysis warnings”.

I am wondering what are those errors and warnings, and how can I make it go away? My understanding is that it may have something to do with the compiler. I compile the same program under Visual C++ Express in Windows, and I don’t see any of those “errors” or “warnings”.

I create a wxWidgets objects, e.g., wxTextCtrl, and hit Ctrl + Space, but I don’t see any member variables or methods there. Does it have anything to do with those “semantic errors” and “warnings”?

Thanks.

    CDT does not know about your project’s header search paths in your makefile unless you tell it about them.
    Go to the Project properties > C/C++ general > Paths and Symbols and add any header search paths used by your project there.

    enter image description here

    You probably have those set up in Visual C++ already so you can look there to see which paths you need to add.
