Unable to export FMU with S-function target in Model Exchange mode with FMI Kit 2.8

[krishnashukla201]

I got a issue when trying to export simple model through s-function target for Model Exchange.
I simply created a new enum type BOOL_TYPE and some other typedef to use in my model.
During the FMU export for that model, when it generate model_interface.c file it create 2 times case with same value 8 and create 3 times case with value 0.

size_t getCGTypeSize(int typeIndex)
{
switch (typeIndex) {
case 0:
return 8; /* real_T */

case 1:
return 4; /* real32_T */

case 2:
return 1; /* int8_T */

case 3:
return 1; /* uint8_T */

case 4:
return 2; /* int16_T */

case 5:
return 2; /* uint16_T */

case 6:
return 4; /* int32_T */

case 7:
return 4; /* uint32_T */

case 8:
return 1; /* boolean_T */

case 9:
return 0; /* fcn_call_T */

case 10:
return 4; /* int_T */

case 11:
return 8; /* pointer_T */

case 12:
return 8; /* action_T */

case 13:
return 8; /* timer_uint32_pair_T */

case 8:
return 1; /* BOOL_TYPE */

case 0:
return 8; /* TemperatureType */

case 0:
return 8; /* Q16_15_TYPE */

default:
return 0; /* unknown type */
}
}

Error given in Matlab is

model_interface.c
D:\Manmohan\REF\Ref_V6\work\test_func_sfcn_rtw_fmi\model_interface.c(49): error C2196: case value '8' already used [D:\Manmohan\REF\Ref_V6\work\test_func_sfcn_rtw_fmi\test_func.vcxproj]

please let me know the solution.

To reproduce - Create a simple model and add some user defined enum types(boolean) and typedef(any base type). assign variables in the model with these enum or typedef. Then export the FMU. it will through this error.

@krishnashukla201, can you share an example model to reproduce the problem?

[krishnashukla201]

test_sfcn.zip
sample model.

@krishnashukla201, can you give f3e14a8 a try?

[krishnashukla201]

By using this new file i am getting this error now.

I can successfully export the above model with R2020a if I remove the sources in Configuration Parameters > Simulation Target (these are not required for the model).

Please re-open if the problem persists and provide steps to reproduce.
