推荐答案
unistd中的 uni代表 UNIX-您
The "uni" in unistd stands for "UNIX" - you won't find it on a Windows system.
使用最广泛的可移植库应提供替代的构建或检测平台,并且仅尝试使用将被使用的标头/函数。提供,因此值得检查文档以查看是否错过了一些构建步骤-例如也许运行 make而不是加载 .sln Visual C ++解决方案文件。
Most widely used, portable libraries should offer alternative builds or detect the platform and only try to use headers/functions that will be provided, so it's worth checking documentation to see if you've missed some build step - e.g. perhaps running "make" instead of loading a ".sln" Visual C++ solution file.
如果需要自己修复,请删除包含的内容并查看实际上是哪些功能需要,然后尝试查找Windows等效项。
If you need to fix it yourself, remove the include and see which functions are actually needed, then try to find a Windows equivalent.
