我的代码(https://github.com/fangq/mmc，https://github.com/fangq/mcxcl)已经在Linux&Mac、Windows上的cygwin gcc或msys2 gcc，但没有使用MinGW编译器(适用于cygwin64、msys2、mingw64或TDM-gcc的x86-64-mingw64-*编译器，或matlab mingw64支持(mingw64 gcc 4.9.6((，因为它抱怨错过了一组头文件(sys/ioctl.h、ieee754.h等(，所以我在源代码中包含了这些头文件的副本，并添加了-I./mingw64/include以使大多数头文件编译
https://github.com/fangq/mmc/tree/master/src/mingw64/include
然而，当在matlab R2016/2018上使用此脚本编译matlab mex文件时，我收到了以下错误
Error using mex
mcx_utils.o: In function `mcx_progressbar':
D:/Users/fangq/Gitroot/Project/mmc/src/mcx_utils.c:1054: undefined reference to `ioctl'
collect2.exe: error: ld returned 1 exit status
我想知道为什么在matlab内部和外部编译是不同的。有没有可以链接的库来修复undefined reference to "ioctl"错误？
以下是在msys2:上使用gcc编译时的日志

从其他地方复制该标头是个坏主意。充其量，它会定义库不存在的函数，从而导致链接器错误。
通常，你需要使用Windows替代品来处理你在其他平台上做的任何IOCTL事情。
