Using a c keyword as a Modelica variable name doesn't work

[Sam.Lishak@…]

I created a model with a parameter called "switch" in it. The compilation failed because it gets translated into C in [Model]_functions.c without mangling the name at all, and "switch" is a reserved keyword in C.

I cannot reproduce this for the c runtime, but the code for the Cpp runtime seems to be invalid since the variables get translated into C++ as they are in the model (OMCppMFunctions.cpp).
Can you provide a small test case? In my example, the variable switch get a underscore as prefix in the generated code ([Model]_functions.c).

Can you tell us also what OpenModelica version are you using?

[Sam.Lishak@…]

Ah, sorry, there appears to be more to it than that. You need to create a record containing the parameter switch. I'm using OpenModelica 1.9.3. The following model should reproduce it:

model BaseModel
  record Config
    parameter Boolean switch = true;
  end Config;

  Config config;
  
end BaseModel;

which generates the following c code in functions.c:

#include "OMTest.BaseModel_functions.h"
#ifdef __cplusplus
extern "C" {
#endif

#include "OMTest.BaseModel_literals.h"
#include "OMTest.BaseModel_includes.h"


/* Next line uses "switch" with no leading underscore */
OMTest_BaseModel_Config omc_OMTest_BaseModel_Config(threadData_t *threadData, modelica_boolean switch)
{
  OMTest_BaseModel_Config tmp1;
  tmp1._switch = switch;
  return tmp1;
}

modelica_metatype boxptr_OMTest_BaseModel_Config(threadData_t *threadData, modelica_metatype _switch)
{
  return mmc_mk_box2(3, &OMTest_BaseModel_Config__desc, _switch);
}

#ifdef __cplusplus
}
#endif

I see! Thanks for reporting this issue.
