Simulink Real-Time Build Error: Undefined identifier xPCLoadParamSetFile in xpcoptions.tlc

Hello,

I am trying to build a model in Simulink Real-Time (Matlab 2020a). However, I am always encountering the following build error (even if my model only consists of a constant and a scope). As a compiler, I use Visual Studio 2019 Community.

I have tried to change anything the box in the "Hardware Settings/Simulink Real-Time Options"-Pane, but I cannot apply the changes because of an error pop-up saying: "Dot indexing is not supported for variables of this type." These (unchangable) settings can be found below.

On two other PCs of my co-workers the model works with the same Matlab and VS Versions.

I hope someone has an idea how to fix this error. Thank you very much in advance!

I have the same problem, can anyone help? I am running out of options.

Answer 1

[Jakob Thumm]

I faced the same issue.

For me, reinstalling the speedgoat_setup worked.

If everything fails, wipe Matlab clean and reinstall everything.

From what we know, this is an error that only appears after installing Speedgoat I/O Blockset. To prove this, run the following commands to temporarily remove Speedgoat I/O Blockset from your installation:

>> restoredefaultpath
>> rehash toolboxcache
>> sl_refresh_customizations
>> load_system('xpcosc');
>> slbuild('xpcosc')

If the build for the 'xpcosc' model works without errors when running the commands above, please contact Speedgoat Support for further assistance: https://www.speedgoat.com/company/contact-us

If the slbuild('xpcosc') command still produces errors , contact MathWorks technical support: https://de.mathworks.com/support/contact_us.html
