ASN1 to AADL failed

[ArMourMag]

Hello,

I'm using ESROCOS for H2020 project and I need to create ASN1 types but the conversion process failed.

The error message is:

There is same problem with the command esrocos_fetch_dependencies.

Command finished successfully at 2019-11-06 09:46:51 +0100
compiling shared types...   DONE
compiling types to aadl...  
Compilation of generated sources failed - is b'cc' installed?
(report inside '/tmp/tmpaez2p3xo.asn1c/ShowNativeBuffers.stats.err')

Thanks for help.

Could you please provide some additional information?

• Which platform or VM you are using
• What is the ASN.1 file that you're trying to compile
• What commands or steps you are using to compile them

I use Lubuntu 18.04 VM given by you (I'm Arnaud Moura - Magellium).

The "CC" error was a problem of definition and now it's fixed.

Now I want to import my ASN1 file in TASTE DataView and it isn't possible because I have a GLIB error.

With this problem I can't import my file and save any modifications in DataView.

The GLIB error is related to the windowing environment, and it doesn't in principle affect the data view generation. They can be ignored.

Nevertheless, there is something not working in the GUI when an existing ASN.1 file is imported. I get an error message related to fonts.

As a workaround, I suggest that you create the DataView.aadl file from the command line. Just go to the directory containing the TASTE model and run:

taste-update-data-view ../../install/types/base/taste-extended.asn ../../install/types/base/userdefs-base.asn ../../install/types/base/base.asn

Adjust the .asn files to process and the paths as necessary for your model. Then re-open the model with the command taste-edit-project. In my test, the Data View section was correctly updated.

For our use of TASTE, we often create a script in the model directory to run the taste-update-data-view command with the required files. It's more convenient to use the script whenever you change the ASN.1 types, than to unload and reimport them with the graphical editor.

Please, let me know if the workaround works for you.

We'll check with the TASTE people to investigate the underlaying issue with the editor.

The command taste-update-data-view doesn't import new asn file.

The result says All OK but nothing in the Taste editor.

What ASN file can I change ? taste-types.asn ?

Please, check if after running the taste-update-data-view command the file DataView.aadl has been updated, and whether it contains at the top of the file the list of .asn files that should have been processed.

Below you can see how the first lines of the DataView.aadl file should look after running the taste-update-data-view command successfully:

package DataView

public

...

Once the DataView.aadl file is updated, the editor should show the correct information. You will need to close and reopen the editor for the information to show.

I checked and it's ok. Would there be a fix of TASTE in the future ?

[mmunoz-gmv]

There are a couple of issues in the VM configuration that produce the DBUS errors, and possibly some errors with fonts.

To remove the DBUS errors in Gtk apps, do sudo apt-get purge fcitx-module-dbus. This uninstalls a Gtk module (I think it's for emojis) that causes problems. It indicates that other packages such as lubuntu-desktop will be uninstalled, but in principle this is safe.

After updating TASTE, I also got some errors with missing fonts. To solve those, do sudo apt-get install xfonts-base.

Thanks, I will try next time because I'm an other problem.

When I run the build command esrocos_build_project I'm this error:

Everythings is okay. The command esrocos_build_project change encoding of files ?

I think this might be related to an issue with the Python environment variables. In your error log, I see that there is an error in a library for python3.6. However, if you run /usr/bin/env python in the VM, you probably get Python 2.7. Could you please check this?

As a workaround, please try to manually set the environment variable PYTHONUSERBASE, removing the path to the ~/.local-lib/python3.6/site-packages directory, and leaving the rest as it is.

Take a look at ESROCOS_D4.4 section 4.4.3 for an explanation of the problem.

By the way, the ESROCOS scripts under tools/workflow (esrocos_build_project, etc.) were developed by DFKI. Maybe they can help you better.

This manipulation resolves the problem. Thanks.
