Unable to get IResource for Resource when running

[nuaaysh]

Dear Authors of Ocarina,
I have two questions about the Ocarina:
Firstly, Where can I find the details about how your tool generates PolyORB-HI/Ada code from AADL models? I only find the PolyORB-HI/C part in the User’s Guide.
Secondly, as the title said I get an error message when I try to use Ocarina to generate Ada code.

The test example is from your example https://github.com/OpenAADL/polyorb-hi-ada/tree/master/examples/aadlv2/prime_numbers

some information is listed as follows:
OS Ubuntu20, x64
OSATE2: 2.7.1.vfinal
OSATE2-Ocarina plugin 0.0.1.201302151532
Ocarina 2017.x (Working Copy from ree7273d)

Many Thanks!

PolyORB-HI/Ada has its own doc that you can build separately.
The second part should have been addressed, the plugin version you use does not make sense. OSATE has a specific mechanism, to install extension; check Install Additional OSATE Components from Help menu. From there; you can install a more recent version of the plugin

Dear Prof. Jerome Hugues,
Many thanks for your reply, now I get the latest version and the source doc of PolyORB-HI/Ada. But I test the example, it still reports an error:ADA.IO_EXCEPTIONS.USE_ERROR.(below)
I try to google it or check the User's guide, But I can't find a solution.

  Could you please give me some suggestions?

Best wishes,

Which example are you testing? All PolyORB-HI/Ada examples shipped with the source code release are tested, see https://travis-ci.org/github/OpenAADL/ocarina

Check the file actually exists

Hello, Prof. Jerome Hugues,

The example is from https://github.com/OpenAADL/polyorb-hi-ada/tree/master/examples/aadlv2/prime_numbers

[yoogx]

Do not try randomly ... this example is meant to be compiled for Native platform,

You may want to change this from LEON_ORK to Native
'''
processor the_processor
properties

• Deployment::Execution_Platform => LEON_ORK;

• Deployment::Execution_Platform => Native;
  end the_processor;
  '''

then you need to update Ocarina to have patches for this issue #262
note they are independent of the bug you mentioned.

Many Thanks! I have modified the AADL model.

But now the error still exists: "Detected exception: ADA.IO_EXCEPTIONS.USE_ERROR", so I can't use the ocarina-osate plugin on my Ubuntu.

Could you please give me some suggestions?

[yoogx]

You did not tell me whether the file exists or not; I would recommend you try with GNAT Community Edition 2019 if you use GNAT from Ubuntu

[nuaaysh]

Sorry, my mistake!

So please check the picture: The .abs exists and the ocarina terminal says there is an error: can't copy the abs.file! But I also get the target Ada code including the .abs file!!!

Issue #264 addressed a bug with GNAT CE 2020. This should now be corrected
