Activation?

[Theo]

Hi,

I tried to link Matclipse to my (legal, activated) binary of Matlab
2011b. However, as soon as I start eclipse, as the matlab terminal is
trying to open, the Matlab activation windows pops up (for the record,
when I simply launch matlab, no such thing happens). Even if I
complete activation, the matlab terminal window in eclipse says
something like 'matlab could not open' (if i don't complete
activation, eclipse freezes! :) ).

Any clue about why that could be? I am using a year old macbook, osx
lion fully updated, eclipse indigo, latest matclipse, matlab 2011b (or
a, didn't help).

Hi Theo!

This sounds like a serious problem. Since we have a campus license, I cannot check this - here it's working fine. Maybe someone else with a Mac and a private license could share some experience with you. Btw, the first thing I could think of is, that your Matlab path was configured to another installation. It should be set in the prefecences to /Applications/Matlab....

Since you seem to have several versions of Matlab on your computer,
did you double-check which version was called by matclipse ? Could it
be that matclipse is trying to launch an old version, whose license is
now expired ?
Sorry if you already double-checked this, but it already happened to
me (not with matclipse, though), since I always keep 2 or 3 versions
of Matlab on my computer -- and macosx's PATH setting is sometimes
sketchy.

Hope this helps,

Julien

Hi!

Thanks for your help.

I tried 2011B, 2011A, and even 2010a releases - all are activated (as
it happens, Matlab activates once for all installs simultaneously,
it's MAC id based).
I changed which one i was pointing by changing the matclipse path from
Applications/MATLAB_R2011b.app/bin to something like Applications/
MATLAB_R2011a.app/bin

I think that the splash screen of the activation even indicates which
version Eclipse is trying to run. All the versions I have run outside
of Eclipse.

The weirder thing is, if i go through with the activation, Eclipse
just says 'matlab couldn't start', and no record of such activation
occurs on the math works license manager. And I can keep doing it and
doing it again, the activation always goes through, but not
matclipse :)

To be honest, this sounds more like a problem with matlab, but i was
hoping maybe a simple fix would save me.

Cheers,

Theo

I am starting to wonder if i installed matclipse correctly (though i
followed the instructions precisely), because i just installed octave,
and matclipse won't work even that, which shouldn't have any
activation...

[Christopher Albert]

OK, so that's a different thing... I think also other people had that problem on Mac. Could you try checking out the sources from git and running directly from sources? If that is working, we have a problem with the update site release!

[Theo]

Built the whole project by hand. Still does not work :/

I will try on a windows partition and let you know if it's any
different.

Thanks for the help,

Theo

Ok, I tried two more times.
Once, on a brand new windows 7 image. New eclipse install, new matlab
install, new matclipse install. Same problem at first! Even though
matlab was definitely activated (and there is only one version on
disk), it tried to activate again. But then, miracle - after that new
'fake activation', it works.

Just for verification, I tried with a .. less 'clean' version of
matlab (i do have a license after all), on os x, and it worked then.

Bummer, maybe it only works with uni licenses on os x?

[Christopher Albert]

Now this is strange... it seems, that it works with network
licenses... can anyone else with a private license reproduce this
problem? The only way to test it for us would be to get a trial
license, when I have time, I will try, but it could take a while.

Thanks a lot for the info and hopefully, we will sort this out!

Best regards,

Chris

If you mean under windows, I have a standalone license on my work
laptop that is working fine.

[Theo]

It also works under windows for me. I think os x is the one having the
issue.

[Christopher Albert]

The mechanism of starting Matlab is quite different between the two
platforms. On Windows we are using COM+ (jacob and win32 plugins) and
on MacOS a pipe like on Linux. This could be the reason why they
behave differently. The question now is, if there is the same problem
on Linux with standalone licenses. Does anyone have experience with
that?
