[SOLVED] PIL simulation error for a new target

Hi there,

I created a new STF+Connectivity Config for new target processor. Unfortunately I cannot get it to run. During the build process an error throws up, which I cannot interpret.

The build log looks like this:

    ### Model reference SIM target (subtest_mb_msf.mexa64) for model subtest_mb may be out of date because the model information cache has been updated.  The model or library files may have been resaved or a referenced configuration set may have been modified.

      ### Successfully updated the model reference SIM target for model: subtest_mb
    ### Model reference RTW target (subtest_mb.c) for model subtest_mb is out of date because subtest_mb.c does not exist.

    Warning: You are using gcc version "4.4.3-4ubuntu5)".  The version
             currently supported with MEX is "4.3.4".
             For a list of currently supported compilers see: 
             http://www.mathworks.com/support/compilers/current_release/

Some of the output is from my ConnectivityConfig and TargetApplicationFramework respectively.

At this point I get the error messages "An error occurred while calling into the SIL or PIL target connectivity implementation", "Invalid function name ''" and "Error while bringing model references of model test_mb up to date: see errors reported above for details".

My system is glnxa64 by the way.

What is that supposed to mean? Which function name is empty there? Unfortunately there is a lack of documentation what Embedded Coder is doing at this point...

Thanks, martin

You might need to contact MathWorks Tech Support for this because it seems like it might need some involved debugging. One tip that I can give is to try running "dbstop if all error" and then run the model again to see if MATLAB stops at the point that the error occurs. If the error is coming from a .p file, it may not be much help though. Sorry for not being able to help more!

Don't be sorry, you made my day! Thank you very much for the continuative tip! Indeed the breakpoint hit something, see:

Caught-error breakpoint was hit in StorageMapper.StorageMapper>StorageMapper.getStorageForModel at line 141. The error was:

Error using StorageMapper.getStorageForModel (line 141)

Model needs to be saved before you can add externally stored RMI data.

### Checking for structural changes in rtwdemo_sil_counter_mb because the model reference rebuild option is set to 'If any changes detected'. Structural changes will cause the model reference SIM target to be rebuilt.

From that I figured that R2011b was looking for my pil_make_rtw_hook.m file, which I did not create, since I don't need it.

The solution is to create this function file anyway and - in my case - just leave the function empty.

It should be noted that in R2012a it works without such a file.

Again, thank you very much!

Best Regards,

Martin: Glad I could be of help. Thanks for posting you solution. :)
