I’ve been trying to build the Urho Sample Platformer. I’ve been filing bugs and the author of USP has been fixing them. We are currently having a problem with WinMain being undefined. Despite superficial appearances, I don’t think it’s getting any “WIN32” define to trigger correct behavior in Core\main.h. When I run a preprocessor my main.i output is
int RunApplication()
{
Urho3D::SharedPtr<Urho3D::Context> context(new Urho3D::Context());
Urho3D::SharedPtr<USP> application(new USP(context));
return application->Run();
}
int main(int argc, char** argv) { Urho3D::ParseArguments(argc, argv); return RunApplication(); };
Visual Studio believes that DEFINE_MAIN is defined in Core\main.h as:
#else
#define DEFINE_MAIN(function) \
int main(int argc, char** argv) \
{ \
Urho3D::ParseArguments(argc, argv); \
return function; \
}
#endif
Now, the earlier #ifdefs are governed by “WIN32”. However the correct preprocessor define according to the VS 2015 documentation is _WIN32. msdn.microsoft.com/en-us/library/b0084kay.aspx “Defined for applications for Win32 and Win64. Always defined.”
Now, Core\main.h is an exported header file. Why should it be assuming that a CMake define, WIN32, would be used? Isn’t a platform define _WIN32 the more correct way to do things? web.archive.org/web/20140625123 … ing_system seems to indicate that _WIN32 is the correct macro for all Windows compilers, not just Visual Studio.
