DESCRIPTION:

Hello.
I'm trying to use ocarina to generate a mast model from an AADL file on OSATE 2.3.4.vfinal but I get this error:

ocarina: Cannot find a root system
+========================== OCARINA BUG DETECTED =========================+
| Detected exception: STORAGE_ERROR |
| Error: s-intman.adb:136 explicit raise |
| Please refer to the User's Guide for more details. |
+=========================================================================+
raised STORAGE_ERROR : s-intman.adb:136 explicit raise.

I'm not sure if this error is related to the addl file (like correct properties for components) or not, but I tried to generate a MAST model for simpler AADL files and it works. By calling other options like "generate statistic", "generate petri-net" and ... I get the same error. I should point out that I'm using Ubuntu VM on Mac.
Do you think that this issue could be related to memory and is there any option for increasing memory for performing code generation?

Hi,

this error message is relevant: ocarina: Cannot find a root system
It means there is not root system, and the tool exits (a little bit abrupt, I concede)

A root system is a system implementation without features. Ocarina can only proceeds these. The rationale is that a system with features would interact with external blocks not modelled, and thus can provide any relevant results.

AADLib provides example of valid systems that can be processed by Ocarina

Thank you for your quick response :)
I removed the system features and it works now.

Perfect. I close the issue
