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
however, when compiling the matlab mex file using this script on MATLAB R2016/2018, I received the below error
Error using mexmcx_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 statusI 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?
Here is the log when compiling using gcc on msys2:
