C ++头文件显示Windows不兼容错误

Question

When attempting to create a .h file in order to store a class such as in the example below:

#ifndef TRIANGLE64_H
#define TRIANGLE64_H

class Triangle64{
public:

 Triangle64();

 double getArea();

 void destroy(); //Frees the allocated memory

private:

//Variables reflecting the properties of the triangle
 double Base;
 int N_ulps;
 double s;
 double Area;
};

#endif

I am returned with the error:

This version of C:\\Users\\ezio1\\AppData\\Local\\Temp\\Triangle64.exe is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher.

Which seems quite strange as I am not attempting to make a .exe file from this code (and for completeness I am also running Windows 10 with the gcc compiler).

I have also tried ignoring the error message and attempted to create a class file from the header:

#include "Triangle64.h"

//Constructor
Triangle64::Triangle64(){

}

However, the code does not even run this time and I am returned with the error message

c:/mingw/bin/../lib/gcc/mingw32/5.3.0/../../../libmingw32.a(main.o):(.text.startup+0xa0): undefined reference to `WinMain@16' collect2.exe: error: ld returned 1 exit status

Could this be a result of an issue with my installation of the compiler or perhaps something to do with the OS?

Answer 1

It looks like you're building a 16-bit application, based on the second error message. 64-bit versions of Windows can't run 16-bit executables due to a limitation of the x86 architecture.

Change your compiler settings to build 32-bit or 64-bit code.
