target=msvc

Dec-15-15 23:28:10

Hi all, I'm using OpenModelica 1.9.3. When I'm compiling a model with target set to msvc I'm getting this error:

Code:

IModel.obj : error LNK2019: unresolved external symbol _checkForSynchronous referenced in function "int __cdecl IModel_performSimulation(struct DATA *,struct threadData_s *,struct SOLVER_INFO *)" (?IModel_performSimulation@@YAHPAUDATA@@PAUthreadData_s@@PAUSOLVER_INFO@@@Z)

Any idea how to solve that, please?

Thanks, Josef

I tried, but I'm still getting an error.
Please, any idea why?

Thanks!

Ok, it seems we're not compiling and linking some runtime code for the MSVC C target. I'll open a ticket about it and have a look.

Maybe it works better with the C++ runtime: +simCodeTarget=Cpp.
In OMEdit try to choose Cpp from drop-down options of Target Language and msvc
from drop-down options of Target Compiler in Tools->Options->Simulation and try to
build again.

I tested the Cpp code target with msvc, but it does not work. I got quite a bit of warnings and errors about undeclared identifiers:

error C2065: 'tmp39' : undeclared identifier
error C2065: 'tmp39' : undeclared identifier

and about syntax error:

error C2146: syntax error : missing ';' before identifier 'tmp39'

Thank you for your help.

When I use Cpp target for a simple model it does compile the model. It looks to me it has something to do with change() function in the when-statement.

Also I found some issue in C++ generated code (see bellow), the second else if statement starts wrongly with forward slash.
When I delete this then I can compile the Cpp target by re-running nmake.

Code:


void IModel::evaluate_482()

{

  if (_initial)

  {

      ; // nothing to do

  }

  else if(0 || (_$whenCondition15 && !_discrete_events->pre(_$whenCondition15)))

  {

    _state_var_reinitialized = true;

      __z[24]   = 0.0;

  }

  /else if(0 || (_$whenCondition14 && !_discrete_events->pre(_$whenCondition14)))

  {

    _state_var_reinitialized = true;

      __z[24]   = 0.0;

  }

  else if(0 || (_$whenCondition13 && !_discrete_events->pre(_$whenCondition13)))

  {

    _state_var_reinitialized = true;

      __z[24]   = 0.0;

  }

  else

  {

     ; // nothing to do

  }

}

Thanks.

Hi Josef,

I am Akshay. I am trying to compile the model with cpp and msvc targets. I am getting the same errors as you have stated. How did you manage to solve this issue? Please help me. It is very important for me to use this compiler so that I can co-simulate this model with Carmaker.

Thank you in advance

Best Regards
Akshay

Hi  Akshay,

unfortunately I had to give up this activity. Only simple model could be compiled. More complex models would require manual checking which is very difficult.

There are other way to co-simulate with CarMaker. What about making FMU out of your model.

Regards,

Josef

My company requires me to model the physical components using Open Modelica. So do you mean, there are tools where the modelica models can be exported into FMU for co-simulation with CarMaker?? Can you please suggest me any such tool where I can export my modelca model to FMU.

Thank you so much for your time. I appreciate your help.
