“错误:在为64位编译时,pthread.h上的“{”标记“之前应为标识符或“(”

我发现了之前关于此错误消息的问题,但它们与我的情况不匹配,以下是场景:

环境 :Windows 8.1和根据配置64位GCC的代码块=> How do I compile for 64bit using G++ w/ CodeBlocks?

问题 :测试中列出的基本多线程简单程序=> https://www.geeksforgeeks.org/multithreading-c-2/ 具体如下:

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

// A normal C function that is executed as a thread 
// when its name is specified in pthread_create()
void *myThreadFun(void *vargp)
{
    sleep(1);
    printf("Printing GeeksQuiz from Thread \n");
    return NULL;
}

int main()
{
    pthread_t tid;
    printf("Before Thread\n");
    pthread_create(&tid, NULL, myThreadFun, NULL);
    pthread_join(tid, NULL);
    printf("After Thread\n");
    exit(0);
}

在标准32位中编译此文件可以完美地完成并工作,但在使用 MinGW-64 ( 如何使用带有代码块的G++64位进行编译? )它失败,pthread上出现4个错误。h:

pthread.h|418|error: expected identifier or '(' before '{' token|
pthread.h|428|error: expected identifier or '(' before '{' token|
pthread.h|438|error: expected identifier or '(' before '{' token|
pthread.h|447|error: expected identifier or '(' before '{' token|

不言而喻 pthread。h类 未以任何方式进行修改或更改。错误指向四个 #定义 线:

其他程序编译并正确运行64位,运行时在进程的详细信息中显示。 我不明白为什么只有在编译64位时,相同的未修改的头文件才会显示错误。生成日志显示:

我承认我只是这些领域(多线程、64位程序)的初学者,所以如果我的问题对专家来说很明显,我深表歉意,但经过长时间的研究,我在之前的帖子中找不到任何帮助,我陷入了困境。

非常感谢您提供的任何帮助。
