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
