MATLAB coder settings for generating code for external project c/c++

Depending on the settings, applying MATLAB coder on a filename.m generates as a minimum these files:

• filename.h, filename.c, filename_types.h, rtwtypes.h, filename_initialize.h, filename_initialize.c

Is there any option the get to content of filename.h & filename.c coded in a filename.h file only?

• In filename.h there are the includes #include <stddef.h> and #include <stdlib.h>

Is it possible (by any settings) to get rid of this auto-includes?

There is no such feature at this point.

Is there any reason you want everything in one header?

The usecase, with the idea to set up an automated flow, is:

• test_main.m calls a main.m and a functinonal equal mex-wrapper/main.cc
• config.m just includes constants for different configurations -> used by main.m
• config.m -> MATLAB coder called from test_main.m -> C/C++ file containing these constants -> used by main.cc
• mex-file is compiled with "C/C++ file containing these constants" on the fly
• when "cosim" passed -> main.cc is used in another C++ environment
• issue 1: include files stdlib.h, stddef.h crashes in other C++ environment
• issue 2: compile errors occur when compiling/linking config.c/config.h while including a config.h containing the constant declarations works perfect

Issue 2 might be solved by further investigations but just binding some constants into a C/C++ file it's an overhead and moreover it's confusing if at least 6 files (see above) have to be included.

Besides this approach if there is any other convenient way to pass the constants with the required C++ type defs on the fly into the C++ world I would like to use it. Any suggestions?

config.m contains a MATLAB function with a configuration select input parameter and (for example) a struct containing all constants as return parameter
