当你遇到编译错误“undefined reference to __errno'”时,这通常指示链接器(linker)在尝试生成最终的可执行文件或库时,找不到__errno的定义。这个问题在C或C++项目中较为常见,尤其是当使用了标准库函数,这些函数内部可能会使用到errno变量(通常__errno是errno`的内部表示或别名)。以下是一些解决步骤: 确认上下文:...
w_sqrt.c:(.text.sqrt+0xa8): undefined reference to `__errno'collect2.exe: error: ld returned 1 exit statusI've tried everything I can find suggested here & elsewhere ( mainly revolving around linking the math library with -lm, but this makes no difference.)I was kinda hoping that a...

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'

: 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...
