Mex is configured to use Microsoft Visual 2022 for C++, I have also switched to the 2019 option. I have reason to believe that this had to do with changes made in the latest 2023b release. I generated code with the 2023a a while back, but with the same compiler setting I am now seeing compiler errors in 2023b. The Python environment is created with v3.10.

I am testing code generation with the following basic ROS2 publisher node.

function mynode2
    %#codegen
    %setenv('RMW_IMPLEMENTATION','rmw_cyclonedds_cpp')
    domainID = 10;
    Name = "/PosePrintNode";
    PoseNode = ros2node(Name, domainID);
    pose_sub = ros2publisher(PoseNode, ...
        "/chatter","geometry_msgs/Pose");
    % Display X position
    msg = ros2message("geometry_msgs/Pose");
    while (1)
     msg.position.x = rand(1);
     fprintf("Position = %f\n",msg.position.x)
     send(pose_sub,msg)
    end
    end

Hi Andinet,

With this exact same code and the following configuration setting, I am not able to reproduce this issue on my R2023b MATLAB:

>> cfg = coder.config('exe');

>> cfg.Hardware = coder.hardware('Robot Operating System 2 (ROS 2)');

>> cfg.HardwareImplementation.ProdHWDeviceType = 'Intel->x86-64 (Windows64)';

>> cfg.Hardware.BuildAction = 'Build and load';

>> codegen mynode2 -config cfg

Is there any log got generated? The error message says "See Build Log for further details", is there any hyperlink associate with it?

Thanks,

Josh

The error log you posteed contains this: View Error Report

This is a hyperlink that should open a UI window, and at the bottom, there is a "build log" tab. Can you look there, what is the contents?

Hi Andinet, I suspect there is some kind of cmake configuraiton issue on your system. Google search for "could not find pkgconfig" gives links like this one:
