Hi,
I don't know if this is a coincidence or not but Skrooge is not able to
load /*_only the plugins using "Plasma" APIs_*/ any more
(The same code works on kubuntu 12.04 but not on 12.10).
Do you think I am on the right track?
Do you have some advice to find the correction?
Thank you.

Hi,<br>

I don't know if this is a coincidence or not but Skrooge is not able

any more <br>
(The same code works on kubuntu 12.04 but not on 12.10).<br>

<br>
Thank you for your answer.

Now, I know the reason of the error (not due to KDE or Skrooge,
due to libc) ...
<br>
... do you know how to repair it?
<br>
<br>
Do I have to put special linking "tags" in the CMakeLists.txt of
my plugins?
<br>
Do I have to open a bug on KPluginLoader?
<br>
<br>
Is somebody else has the same kind of issue with plugins?
<br>
<br>
Thank you.

I didn't change the code of Skrooge in between.

If I print the error message returned by

this:

/*dlopen: cannot load any more object with static TLS*/

I don't understand this error.

What does it mean?

What should I do to be able to load all plugins like on
previous version?

the error is coming from libdl (the thing that is a few layers
<br>
underneath kpluginloader). And it is apparantly because there
isn't room
<br>
in the DTV to initalize the static TLS.
<br>
TLS is short for Threaded Local Storage (not related to ssl-TLS)
<br>
<br>
the code is in
