The last eclipse-cdt update has broken my c++ perspective

[luca paganotti]

Hi all, I'm searching help about the last eclipse-cdt update carried out on
my fedora 20 box.
It seems I'm not able anymore to load my existing c++ projects, nor create
new ones. I've tried to uninstall and then reinstall all my eclipse
environment few times. I've also tried to rollback to the previous yum
transaction. The c perspective is absent. I've tried also to issue eclipse
with the -clean switch. But no hope for the time being. The last cdt update
is about eclipse-cdt 8.3.0-2 x86_64 and was performed on 2015-03-22.

Is there someone kind to help or drive me to the right source of info?

Thank you for any answer and forgive my italianish ...

Hi Kevin, thank you for your help.

I uninstalled all eclipse packages and then install them again as to have
c++ support issuing yum install eclipse eclipse-cdt as root

I had to completely remove my eclipse metadata from .eclipse in my home
folder, for some reasons, unknown to me, they were non in sync anymore or
they got broken.

After that I got the c perspective back again.

Thank you and have a nice week!

Luca

I also have the updated to the new eclipse-cdt, but I am *not* seeing
what you are.  My old projects are available to me, and I can edit
sources files in my old projects.  My eclipse files are:

I don't know if this is of any help, but it is another data point to
consider.

That is

  https://admin.fedoraproject.org/updates/FEDORA-2014-10650

submitted to updates-testing on 2014-09-10 already and only pushed
into stable updates recently. Notice the feedback in there.

Downgrading is a good idea and may help during trouble-shooting.

Create a fresh user account and try to reproduce the problem there.

Become familiar with the Fedora Updates System website
running an app called "bodhi":

  https://admin.fedoraproject.org/updates/

Locate the update tickets that may be the culprit. In one ticket there
can be multiple packages. Perhaps you've not downgraded all related
packages. Also watch out for new test-updates that may already fix
the problem.

Finally, the links of the form

  http://bugz.fedoraproject.org/SOURCE-RPM-PACKAGE-NAME

    e.g. http://bugz.fedoraproject.org/eclipse-cdt

are a very convenient to Fedora bugzilla and other infrastructure
places, such as a list of currently open problem reports. It may be
necessary to open a ticket there, especially if you can reproduce
the problem in a fresh user account.

Hi Michael, thank you for your prompt answer. I was not even able to
downgrade as my yum rollback command <transaction-id> failed. I'm in the
need to use eclipse, so I uninstalled all fedora eclipse packages and
download  an Eclipse IDE for c/c++ developers from the eclipse website, now
I have in a temporary folder a running instance of Eclipse Mars that I used
to open a little test project and it's building fine.
I've also installed bodhi-client searched on the bodhi website and found
the contents of your next email. I checked my yum repos' setup. I've a
bunch of repos, from planetccrma to jenkins, rpmfusion etc ... but no
testing or debug repos enabled.

I've created a new test user.
Issued yum install eclipse as root
Issued yum install eclipse-cdt as root

logout from my own user and then login as the new created user.
Issued eclipse & and with this new user I've the C perspective back again

Logout the new user and then login with my own.
eclipse & --> no C perspective, not possible to create new projects

I then completely removed my workspace metadata and my user eclipse setup
in .eclipse in my home folder.

Now I have the C perspective back again
I think that in some way my own setup has been compromised, but I'm not
able to say when or to tell the cause.

I think it's not worth to file a bug as the problem was with my own setup
of eclipse.

Thank you very much for your support.

Have a nice day
