You can run "grep -ir LoadImage" to figure out what kind of definition for LoadImage is provided by mingw-w64.
It looks like include/winuser.h has this line: #define LoadImage __MINGW_NAME_AW(LoadImage) So in your header file for your LoadImage class, you can simply write: #undef LoadImage C does not have namespaces. The Windows API from Microsoft defines functions with very broad names, LoadImage, GetLastError, CreateFile, etc. In order to compile Windows software successfully, mingw-w64 has to provide definitions for Windows API functions like that. I would recommend changing the name of your class. When an experienced Windows programmer sees "LoadImage(...)" in your code they might think you are calling the Windows LoadImage functions but you are actually constructing an instance of your class. --David Grayson On Tue, Mar 14, 2017 at 3:42 AM, Mario Emmenlauer <[email protected]> wrote: > > I'm not sure where to ask about this, please redirect me as needed! > > I have a C++ class with a function "LoadImage", which caused a > compile error on Windows.
