I've translated a Matlab algorithm using Matlab Coder. I am in the process of integrating it into a dummy Xcode project. I'm getting the following error:
"tmwtypes.h" file not found
When I searched through the generated code I did confirm that no such file was generated. When I commented out the line, the same issue emerged for:
  • "mex.h"
  • "emlrt.h"

It appears that you have generated MEX code rather than standalone code. MEX C/C++ code is designed to be compiled and run in the MATLAB environment. Whereas standalone code is designed to be run outside of MATLAB.
When generating code, use one of the non-MEX build targets:
codegen foo -args {1} -config:lib
The documentation has more information on the standalone targets, LIB,DLL,EXE and how to specify which one is active.

Dear Ryan,
I have a similar issue with the simulink coder. I am currently working on a simple example in which I want to convert a simulink subsystem (two inputs and one output) which has the following function: y = x1-x2.
I want to convert this block to c-code and to use and integrate this code on a TI TMS570LS microcontroller.
I would like to integrate the generated code into my excisting "code composer studio" (CCS) project.
In the Simulink "Code Generation" setting, I have selected grt.tlc as the target system file. If I do this, CCS requires a lot more header files which are not included in the generated simulink coder folder and these headers seems to be only required in conjunction with MATHWORKS (which I dont want on my microcontroller).
Thank you a lot

In the meantime I found the solution. One needs to activate the "Package Code and Artifacts" option in "Code Generation" Settings. Within the generated package, one finds the folder with the required MATLAB headers.

in windows vs, it is here: C:\Program Files\MATLAB\R2019a\extern\include

You can also use packNGo to package dependencies of the generated code. That knows how to search for such files.
