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?

Thanks

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
