Hi,

I have a non-inlined Level-2 S-Function that I'm trying to integrate in my project. I want to generate the code with Embedded Coder and integrate the resulting C-Code in a broader C Project.

Before adding the S-Function-Block, this worked fine but now, it cannot compile the S-Function .c-File.

I'm getting this compilation error:

I'm compiling with '-DRT'. The missing type is defined in tmwtypes.h. What I'm confused about is that this HelpCenter page states that tmwtypes.h will be included with simstruc.h if used as "Coder Product" - which should be the case here. But in simstruc_types.h it looks as if tmwtypes.h will only be included for MATLAB_MEX_FILE:

#if defined(MATLAB_MEX_FILE) 
    #if !defined(MX_COMPAT_32) && !defined(MX_COMPAT_64) && defined(USE_MEX_CMD) 
        #if defined(tmwtypes_h)
            forceCompilationError tmwtypesbeforesimstrucdetected;
        #else
            #define MX_COMPAT_32
        #endif
    #endif
#include "tmwtypes.h"
#else
#include "rtwtypes.h"
#endif

Ho can I pull in the definition of the type?

Best regards

Matthias

You are better off inlining the s-function. If you'd prefer to not write the TLC code required for inlining the C function, you can use the C Function block or the legacy_code tool.
