1. 解释“implicit declaration of function ‘pthread_setname_np’”警告信息的含义 “implicit declaration of function ‘pthread_setname_np’”警告信息表示在编译过程中,编译器遇到了对pthread_setname_np函数的调用,但在调用点之前,既没有对该函数进行
当没有包含pthread.h头文件或没有添加-lpthread选项时,编译器就无法识别pthread库的函数。因为编译器默认会将未声明的函数当做是int类型的函数,而pthread库中的函数并不是int类型的函数,因此会产生“implicit declaration of function ‘pthread_xxx’”这样的错误提示。 三、解决方案 要解决这个问题,需要在不同的环节...
在这个示例中,pthread_create() 函数的参数正确传递,且代码正确链接 pthread 库。如果还是无法成功编译,可能是由于缺少其他必要的库文件或头文件导致的。 综上所述,“implicit declaration of function ‘pthread_create’” 错误通常是由于缺少 pthread 库头文件或链接选项导致的。添加正确的头文件和编译链接选项,并确...
情况: 用开发板写个小项目,创建线程的时候出现warning: implicit declaration of function ‘pthread_creat’,虽然是warning但make不出来。 解决: 1.函数名pthread_create 2.添加头文件#include <pthread.h> 3.系统为ubuntu 20.04 wsl。pthread库不是Linux系统默认的库,编译的时候需要加上库。在Makefile文件,编译库...
implicit declaration of function ‘pthread_setname_np’ Apparently we need to set: #define _GNU_SOURCE before we #include <pthread.h> Not sure how portable that is. We could also revert it.
