FMU does not compile to x86_64 MacOS with Modelica.Blocks.Tables.CombiTable1Ds

[attila-balint-kul]

I am having trouble with the compilation of any Modelica model from linux to MacOS that contains a Modelica.Blocks.Tables.CombiTable1Ds. I am running OMEdit through XQuartz using the openmodelica/openmodelica:v1.21.0-gui docker image from an Intel MacBook Pro running MacOS 13.4.1. The project runs in virtual environment using python 3.10 with FMPy-0.3.16 installed.

With C code compilation I reached the end of my knowledge and would appreciate the support.

Clang:

Apple clang version 14.0.3 (clang-1403.0.22.14.1)
Target: x86_64-apple-darwin22.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

I created a simplest possible model to reproduce with 1 input, 1 output and a CombiTable.

model TableTest
  Modelica.Blocks.Tables.CombiTable1Ds table(extrapolation = Modelica.Blocks.Types.Extrapolation.HoldLastPoint,smoothness = Modelica.Blocks.Types.Smoothness.LinearSegments, table = [0, 0; 1, 10; 2, 0; 3, 10; 4, 0; 5, 10])  annotation(
    Placement(visible = true, transformation(origin = {0, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  Modelica.Blocks.Interfaces.RealInput real_setpoint annotation(
    Placement(visible = true, transformation(origin = {-120, 0}, extent = {{-20, -20}, {20, 20}}, rotation = 0), iconTransformation(origin = {-94, 6}, extent = {{-20, -20}, {20, 20}}, rotation = 0)));
  Modelica.Blocks.Interfaces.RealOutput real_output annotation(
    Placement(visible = true, transformation(origin = {110, 0}, extent = {{-10, -10}, {10, 10}}, rotation = 0), iconTransformation(origin = {64, -2}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
equation
  connect(real_setpoint, table.u) annotation(
    Line(points = {{-120, 0}, {-12, 0}}, color = {0, 0, 127}));
  connect(table.y[1], real_output) annotation(
    Line(points = {{12, 0}, {110, 0}}, color = {0, 0, 127}));
end TableTest;

I needed to cut part of the logs, but can provide the full if needed.

Can you try to create a CMake project form the FMU by selecting Tools > Create CMake Project... in the FMPy GUI and build the FMU with CMake?

[attila-balint-kul]

Thank you for the quick reply. I have created a CMake project as you instructed using the GUI and ran the cmake . command from the terminal in the project directory (please let me know if did it incorrectly).

I got the following error messages:

There seems to be a problem with the OpenModelica FMU export even with the latest version (v1.24.2). I've create an issue https://github.com/OpenModelica/OpenModelica/issues/13260.
