针对你提出的“undefined reference to `__errno_location'”错误,我将按照提供的Tips进行逐一分析和解答: 确认__errno_location函数的来源和用途: __errno_location是一个在C和C++中用于获取当前线程errno变量位置的函数。errno是一个全局变量,用于指示最近发生的错误。 这个函数通常在多线程

这个sqrt函数不是你自己定义的，是math里面的对吧 错误提示的是没有找到 `errno'include <error.h>或者是#include <linux/error.h>记不清哪个了。然后__errno 改为 errno
构建QEMU时出现如下报错“undefined reference to 'stime'”。 /usr/bin/ld: linux-user/syscall.o: in function `do_syscall1': /root/test/qemu-4.1.0/linux-user/syscall.c:7660: undefined reference to 'stime' collect2: error: ld returned 1 exit status make[1]: *** [Makefile:209: qemu-pp...
: undefined reference to `mysql_errno' collect2: ld returned 1 exit status 出现该错误的原因是因为编译器找不到mysql_init,mysql_close等的具体实现.虽然我们包括了正确的头文件,但是 我们在编译的时候还是要连接确定的库.对于一些常用的函数的实现,gcc编译器会自动去连接一些常用库,这样我们就没有必要自己去...

undefined reference to `err_quit' ; undefined reference to `err_sys’是啥错误? #include"apue.h"#include<dirent.h>intmain(intargc,char*argv[]){DIR*dp;structdirent*dirp;if(argc!=2)err_quit("usage:Isdirectory_name");if((dp=opendir(argv[1]))==NULL)err_s... # include "apue.h"#...
: undefined reference to `err_sys' 解决方法: 因为err_quit跟err_sys是作者自己定义的错误处理函数。所以最简单的解决办法是修改下apue.h文件,如下 /** Our own header, to be included before all standard system headers.*/#ifndef _APUE_H#define_APUE_H#define_POSIX_C_SOURCE 200809L#ifdefined(SOLA...
