使用 winmain 和简单代码编译错误，"Previous decleration of WinMain"

Question

#include <stdio.h> 
#include <windows.h>
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
    return(0);
}

我是C新手，以上代码returns编译时出现如下错误：

main.c:3:5: error: conflicting types for 'WinMain'
 int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
     ^~~~~~~
In file included from c:\mingw\include\windows.h:44:0,
                 from main.c:2:
c:\mingw\include\winbase.h:1263:14: note: previous declaration of 'WinMain' was here
 int APIENTRY WinMain (HINSTANCE, HINSTANCE, LPSTR, int);

Answer 1

您应该使函数定义与库的声明相匹配。你有

int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)

这需要

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)

缺少APIENTRY。

使用 winmain 和简单代码编译错误，"Previous decleration of WinMain"

Compile error with winmain and simple code, "Previous decleration of WinMain"

c

gcc

mingw
