Simulink Coder- Tunable Constants Question

Hi,

The code generated out of Simulink looks a bit off. I am trying to globally expose the following variable. (eventually will be a larger structure).

In the header file, the struct is defined as

/* Parameters (auto storage) */
struct Parameters_CompileAttemp_201107_ {
  real_T TESTING;                 /* Variable: TESTING
                                        * Referenced by: '<S4>/Constant8'
                                        */

};

But the parameter refers the struct as: extern Parameters_CompileAttemp_201107 CompileAttemp_20110705_P;

The struct type name in the definition does not match the with the one referenced in the parameter: Parameters_CompileAttemp_201107 Parameters_CompileAttemp_201107_

Can someone help with the slight difference?

thanks, Becky

Becky: Does the generated code fail to compile? If it does compile, perhaps there is a typedef or #define somewhere that reconciles the difference?

extern Parameters_CompileAttemp_201107 CompileAttemp_20110705_P_

It declares a variable called "CompileAttemp_20110705_P_". Its type is "Parameters_CompileAttemp_201107".

Hi Fangjun,

Let me clafiry,

Parameters_CompileAttemp_201107_ is the name of struct type

CompileAttemp_20110705_P is variable name

not CompileAttemp_20110705_P_

Essentially, the code is correct except I need to remove the '_' at the end. I'm confused why the Simulink Compiler would add this.

Without your modification, does the auto-gen code compile? You are not supposed to hand-modify the auto-gen code.
