S-function and TLC code

Hi! I am trying to run a simulink model that contains a S-function. This Sfun brings C code to my model and the target hardware is the beaglebone black. Basically, i am trying to control EPOS4 driver (Maxon Group Motors) with my beaglebone(BBB), but i am using simulink in a windows computer to create the model and deploy the generated code to BBB. There is a library (EposCommandLibrary) that is installed in beaglebone black so i can communicate with EPOS4 from a linux computer. I found this package here: https://ch.mathworks.com/matlabcentral/fileexchange/60218-epos2-support-for-simulink-coder-in-linux-and-raspberry-pi. I am trying to use it but i receive errors in the Code Generation step, basically saying that the EposCommandLibrary's functions were not recognized : "undefined reference to .....<name of the function>". What I am trying to understand is: when i run the model in External Mode, the code (s-function) is compiled in the beaglebone black? or in the windows computer? Because if it is from windows computer i think i have a problem once beaglebone is Linux and Eposcommandlibrary only have .lib files that depends on the OS.

The .tlc file in the link I mentioned has the lines:

  %assign ret = FEVAL("realtime.addBuildInfoLinkerFlag", "-lEposCmd", CompiledModel.Name)
  %assign ret = FEVAL("realtime.addBuildInfoLinkerFlag", "-lftd2xx", CompiledModel.Name)

So i assumed that tlc file helps generate code for the target file and then the code is copiled in the target. These flags "-lEposCmd" and "-lftd2xx" is used when EposCommandLibrary is being used in Beaglebone or Raspberry.

Please any idea will help!
