DESCRIPTION:

I am new to AADL and to ocarina so this question may be stupid but I could not find a solution yet. I have defined a one package with a data definition in a file named data_defs.aadl, with the following
content:

package data_defs
public
  data mydata
  end mydata;

  data implementation mydata.impl
  end mydata.impl;
end data_defs;

In a separate file I define a system with a reference to that data definition:

package mysystem
public
  with data_defs;

  system mysystem
  features
    inport : in data port data_defs::mydata;
  end mysystem;

  system implementation mysystem.impl
  end mysystem.impl;
end mysystem;

When I run ocarina with
ocarina -vy -aadlv1 -p mysystem.aadl
I get the following error message:

mysystem.aadl:8:15: parsing Package_Specification, Empty packages are not allowed
mysystem.aadl:12:01: parsing AADL_Declaration, unexpected keyword 'end'
Cannot parse AADL specifications

When I run ocarina with AADL v2, it parses the specification. When I put all definitions in a single file, it also works with V1. What is my mistake? Is it not possible to use separate files with V1?
Thanks in advance

AADLv1 is the old version of the standard. v2 adds a couple of new keywords, one is "with" + true namespace. I would recommend you stick to v2, and uses OSATE as IDE to have quickfixes for this type of syntax errors.

Thank you for your explanation. It seems that v1 requires to have the full model in a single file. However, I will follow your advice and change to v2.
I prefer command line tools to Java/Eclipse for various reasons so ocarina fits my conditions better than OSATE.

Sure. I also prefer emacs + text editor.You may want to check this companion project:
https://github.com/OpenAADL/AADLib/

It has (basic) modes for vim and emacs + collection of examples
