I have to create an FMU interface to export a Simulink model. I've downloaded the software from the website https://www.fmi-standard.org/downloads. It requires the xml file and the C-source of the simulink model. When I run the software to create the FMU the error message is
"simstruc.h<285> : fatal error C1189: #error : Unrecognized use"
I've created the xml file using the command "savesystem" in MATLAB. For the C file I've used the target rsim because I used a variable integration step.
MATLAB version used R2011b.
Thanks a lot. Alessandro.

It looks like you may have non-inlined S-functions in your model that the build is unable to handle. What is the System Target File selected in the Configuration Parameters>Code Generation pane?

Hi! Thank you so much. I selected first the "rsim.tlc" because I used a variable integration step, then I selected "grt.tlc" (description: create visual C/C++ Solution file for "grt" target) because I obtained the same results with a fixed integration step during the simulation; the error message is the same..I don't know if could be helpful, but I use windows 7 and I have installed visual studio 2010.

Could you enable verbose build and see if you can get a more detailed error message with grt.tlc?

Hi again. This option was already enabled before generating the C code..The model is a simple mass-spring-damper system, I created all just using simulink blocks (a pulse generator for the input, some blocks to save the output data as variables in the workspace, some blocks to create graphics and load data input, some integrators and a subsystem to create the acceleration), so I do not realize to figure out why it does not work..

What is the C/C++ compiler command being use?

Following the instruction given with the FMU package, I open the cmd window, then I use the syntax "build_fmu me sistMCK", where build fmu open a .bat file, me is a blank file given with the package, and sistMCK is the name of my folder I've created with the xml file, the C code and the other Matlab files. The syntax of the .bat file is this one:
@echo off

Alessandro: Can we stick to debugging with grt.tlc+MSVC?
Alessandro
Alessandro 2012-11-5
Do you mean using the grt.tlc target and Microsoft Visual C++ instead of Microsoft Visual Studio?
Kaustubha Govind

I meant to ask you to try the build without using the "build_fmu me sistMCK" command. Just use the default Simulink Coder build process.
Alessandro
Alessandro 2012-11-5
Ok, I'll try and I'll let you know. Thanks a lot. :)

Hi again. I've still not found a solution for my problem. Do you have any good idea? The problem is always the simstruc. At the line 220 there is the first of seven "if":
#if defined (RTW_GENERATED_S_FUNCTION)
#elif S_FUNCTION_LEVEL == 1
#elif defined(S_FUNCTION_NAME)
#elif defined(SL_INTERNAL) | | defined(RSIM_WITH_SL_SOLVER)
#elif defined(RT) | | defined(NRT)
#elif defined(FIPXT_SHARED_MODULE)
#elif defined(MATLAB_MEX_FILE)
#else
#endif
it seems that no one of the if condition is read, so it goes directly to the else and to the error...

Alessandro: Are you saying that you are seeing the exact same error using the default Simulink Coder build process (ie. without using a custom command like "build_fmu me sistMCK")?
Alessandro
Alessandro 2012-11-15
No, I used the Simulink Coder build process, but I don't need the "exe" file so I tried to use the custom command again. Can I create the "fmu" file using the simulink coder? Do you suggest this to me?

You probably need to fix the Makefile used with the fmu build process to define the right symbol. I would recommend looking at the default Makefile generated by Simulink Coder. In particular look for the symbols used in the seven #ifs that you posted to find which of those you need to define at compilation.
Is there already a solution available for this issue ? Thanks Sathish
