Hi,
We work about extended standard of FMI. I use OpenModelica to execute simulation architectures with several FMUs. Some problems exist but its can be avoided and globally, we are satisfied. We would like use this platform with extended FMI standard but attributes and elements of the xml-file are checked and OM print error. Is it possible to desactivate these checkings or all errors ? Theorically, the ModelDescription is defined in xml_parser.h/c so if we add new elements, that should work with extended version in OM if we keep the original elements and attributes.
Thank you,
Sincerely,
Sulivan Küttler
OM version : OpenModelica 1.9.1 (r22929) (RML version)
Thank you for your help. The c code works now with the a-file. Here my mo-file :

annotation(experiment(StartTime = 0.0, StopTime = 1.0, Tolerance = 0.000001));
end Test;

The a-file has been created with OMShell with this command :
system("gcc -c -a libDocument.a Document.o")
But the a-file is automatically stored in the MinGW ? And the ld.exe linker find the file ?
I read on "https://modelica.org/documents/ModelicaSpec32Revision2.pdf" that for Windows (a-file and so-file for linux), I need to create dll library for dynamic libraries (page 153). How is it possible with OMShell or other tools (I won't use visual studio) ? The a-file or so-file works on windows ?
I would just use c code with dynamic location for the libraries or includes in order to have a portable OpenModelica file (or application) with dynamic c function extension. Is there a easy way to do this ?
For information, I use Windows 7
Thank you.
I c-file is Document.c and I created "libDocument.a" with OMShell (system("gcc -c -o libDocument.a Document.c") which return 0 so it is ok.
However by replacing LibraryDirectory= localPatho, ... by LibraryDirectory="modelica://Document/Clibraries/" , Library="Document", ... that doesn't work. I have to store the a-file in a particular directory ?
Here my mo-file :

It's better because I can see -DOPENMODELICA_XML_FROM_FILE_AT_RUNTIME -lDocument but I have another problem.
Ps : I need to get the local path (get with constant String [:,2] glibraries := OpenModelica.Scripting.getLoadedLibraries()
in order to send this path to the c function which read the file "tab.txt". This part works and the c function read the good path.
The C function are checked directly and the path for reading matrix in file is ok. It's the same for the includes. Only the Libraries doesn't work when a string variable is in annotation, it's localPatho.
This code modelica works because I wrote directly the path of the o-file :

Package of functions allowing linear interpolation of data such as : flow rate coefficients according to the valve lifting laws and the flow direction. These data depend on the cranck angle (between 0 and 720 degres), are stored in a .txt file and arise from external simulations or testing results
