identifier is undefined这一错误通常出现在多种编程语言中,如JavaScript、Python等,具体取决于你的代码上下文。为了准确解答,我们假设这是在JavaScript环境中发生的,因为这是最常见的情况之一。 检查identifier是否已在适当的作用域内定义: 在JavaScript中,如果identifier未在其使用的作用域内定义,就会抛出undefined错误。
undefined identifier是未定义的标志符,在程序内使用了没有被定义的标志符或者变量,是常见的keil编译错误,引发这一错误的原因是你使用的变量没有被定义。解决办法是找到这个没有被定义的标志或者变量进行定义。另外一种常见的错误就是大小写导致的,如你定义的是unsigned char num,在使用的时候,写成了...

在settings.json里添加 { "C_Cpp.default.cStandard": "gnu99" } 关键是那个gnu,因为getopt.h是unix c标准里的,在standard c库里

在header file中实现define variables本身就是错误的,需要move到c/cpp中
