Can't Rebuild ext_comm and ext_serial_win32 MEX-Files which in matlab help

THe code in matlab help seems wrong!

I used This code to Rebuild ext_comm and ext_serial_win32 MEX-Files

cd (matlabroot)
mex toolbox/coder/simulinkcoder_core/ext_mode/host/common/ext_comm.c ...
toolbox/coder/simulinkcoder_core/ext_mode/host/common/ext_convert.c ...
toolbox/coder/simulinkcoder_core/ext_mode/host/common/rtiostream_interface.c ...
toolbox/coder/simulinkcoder_core/ext_mode/host/common/ext_util.c ...
-R2018a ...
-Itoolbox/coder/rtiostream/src ...
-Itoolbox/coder/rtiostream/src/utils_host ...
-Itoolbox/coder/simulinkcoder_core/ext_mode/host/common/include ...
-Irtw/c/src/ext_mode/common ...
-lmwrtiostreamutils -lmwsl_services ...
-DEXTMODE_TCPIP_TRANSPORT ...
-DSL_EXT_DLL -output my_ext_comm

It get a error!

错误使用 mex
ext_comm.c
toolbox\coder\rtiostream\src\utils\rtiostream_utils.h(13): fatal error C1083: Can't open: "rtwtypes.h": No
such file or directory

And i found a file in matlab directory and add it in the command like this

I have solved this Probelm!~

first,foud the rtwtypes.h files in matlab directory,such as toolbox\rtw\accel\accelTemplateFolder,

next the code in matlab help is wrong,use

-Irtw\c\src -Itoolbox\coder\rtiostream\src\utils_host 

instead of

-Irtw\c\src -Itoolbox\coder\rtiostream\src\utils

Use this code we can build the mex file successfully.
