本文介绍了如何使用sys/ioctl.h将代码移植到MinGW gcc?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的代码( https://github.com/fangq/mmc ， https://github.com/fangq/mcxcl )已在Linux& Mac，Windows上的cygwin-gcc或msys2-gcc，但不适用于MinGW编译器(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套头文件(sys/ioctl.h，ieee754.h等)，因此我在源代码中包含了这些头文件的副本，并添加了-I./mingw64/include以便使大多数文件都可以编译
My codes (https://github.com/fangq/mmc, https://github.com/fangq/mcxcl) have been compiled out-of-box using gcc on Linux & Mac, cygwin-gcc or msys2-gcc on Windows, but not with MinGW compilers (x86-64-mingw64-* compilers for cygwin64, msys2, mingw64 or TDM-GCC, or matlab mingw64 support (mingw64 gcc 4.9.6)) because it complains that it misses a set of header files (sys/ioctl.h, ieee754.h etc), so I included a copy of these header files in my source code, and added -I./mingw64/include to make most of them compile
https://github.com/fangq/mmc/tree/master/src/mingw64/include
但是，当使用此脚本编译matlab mex文件时，在MATLAB R2016/2018上，我收到以下错误
however, when compiling the matlab mex file using this script on MATLAB R2016/2018, I received the below error
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
我想知道为什么内部matlab和外部matlab的编译方式不同.有我可以链接的库来修复undefined reference to "ioctl"错误吗?
I am wondering why compiling inside matlab and outside matlab are different. Is there a library that I can link to fix the undefined reference to "ioctl" error?
这是在msys2上使用gcc进行编译时的日志:
Here is the log when compiling using gcc on msys2:

推荐答案
您加入ioctl.h的原因是什么?
从其他地方复制该标头是一个坏主意.充其量，它将定义不存在导致链接器错误的库的函数.
Copying that header from somewhere else is a bad idea. At best it will define functions for which libraries don't exist causing linker errors.
通常，您需要在其他平台上执行的所有IOCTL工作都使用Windows替代方法.
Typically you would need to use Windows alternatives for whatever IOCTL stuff you do on other platforms.
我尝试在Windows上使用MSYS2删除此包含内容来编译MMC，并且构建成功:
I tried to compile MMC on Windows with MSYS2 removing this include and the build succeeded:
patch -ulbf src/mcx_utils.c << EOF

这篇关于如何使用sys/ioctl.h将代码移植到MinGW gcc?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
