By my_username (User), on Sun May 20 12:42:59 2007: Suse 10.2, iconv, PIL and "process exited".

Hello there,

I've read the faq, and I compiled adesklets 0.6 from source (which works just fine under Suse 10.0) and I installed all dependencies. However, every desklet I try to run I gives the following error:

Code:


Do you want to (r)egister this desklet or to (t)est it? t
Now testing...
============================================================
If you do not see anything (or just an initial flicker
in the top left corner of your screen), try `--help',
and see the FAQ: `info adesklets'.

How can I make adesklets work with Suse 10.2 (& Compiz)?

By my_username (User), on Sun May 20 13:00:29 2007.

Wait a minute. This seems to be the same problem I had with Suse 10.0 (I read my own post from some time ago).

I'll try to recompile IMLib2 with png support. Then I'll get back. I'll be back.... (allways wanted to say that! :) )

By my_username (User), on Sun May 20 13:31:57 2007.

Its the same problem I had before (http://adesklets.sourceforge.net/forum/viewtopic.php?t=334&highlight=)

I cannot compile adesklets from source anymore. I recompiled Imlib (it has png support) and I recompiled libiconv.

But if I run make (./configure gave no errors) I get the error:

Code:

It complains about libiconv, but I do have libiconv installed.... The last time a reboot of my computer helped, but now it doesn't.

I tried this (http://adesklets.sourceforge.net/forum/viewtopic.php?t=107&highlight=libiconv) to compile adesklets which worked. But when I try to run a desklet I get the same error as before:

Code:

About iconv:
According to POSIX. Iconv support (libiconv) is supposed to be dynamically linked in from libc: testing for the presence of the appropriate headers (iconv.h) is supposed to be enough. As far as I know, this is always the case with glibc-based system (this includes Suse 10.2) since glibc 2.2 release, back in 2001, so I don't understand what went wrong on your system... Anyway, I will see what I can do to shield adesklets autotools machinery from this without sacrificing portability: it shouldn't be hard, but it could take a while as I will need to perform regression tests.

About running successfully built adesklets 0.6.1:

This just doesn't make sense to me... There is absolutely no dependency from adesklets python module on PIL (Python Imaging Library). Out of curiosity, can you give me the output of:

Code:


env ADESKLETS_ID=0 python -c 'import adesklets'

(It should normally be empty)? Thanks!

my_username wrote:

desklets.error_handler.ADESKLETSError: adesklets process exited -


This is a common, generic error (see the FAQ for explanation)... It could be related to the PIL warning above, or not. Anyway, there is also a fair chance you need to patch the code concerning the FontConfig bug to run adesklets properly on Suse 10.2... Just make sure the standalone interpreter works fine:

Code:


echo quit | adesklets :

Another way around?
Have you tried/considered running a prepackaged version? See here.

First of all: thank you for your fast and detailed reply. :)

The output of that command is:

Code:

I did that, but sadly the source code still does not compile.... (same iconv error as before).

This gives the output:

Code:


Segmentation fault

I'm afraid this is not a good sign? I now think that there is something wrong with my Suse 10.2 installation. I also cannot run certain programs as root (had some troubles logging in as root too: copied the root folder from my other Suse 10.0 installation which solved this). I am thinking of switching back to Suse 10.0 and reinstalling Suse 10.2 (If I can find the time/motivation... ;) ).

That's the first thing I tried with the Smart package installer: It gives this error:

Code:


Traceback (most recent call last):
  File "./adeskclock.py", line 57, in <module>
    import adesklets
  File "/usr/lib/python2.5/site-packages/adesklets/__init__.py", line 43, in <module>
    raise e
adesklets.error_handler.ADESKLETSError: adesklets process exited - 
Exception exceptions.AttributeError: AttributeError("'NoneType' object has no attribute 'kill'",) in <bound method _Communicator.__del__ of <adesklets.communicator._Communicator instance at 0xb7b1970c>> ignored

This is why I tried to compile adesklets from source.The strange thing is that other libraries/applications (like imlib and openFTD do compile from source code...).

If the aforementioned workaround did the trick before, why didn't you used it this time? Seeing the core interpreter segfault tell me you need to generate a patched version corrected to work with the new FontConfig memory scheme. In fact, there is a chance this fontconfig bug will be your only "fatal" condition.

I am not familiar with dependency tracking on SuSE, but I think that would be the time to notify the packager then... Unless you have a hand-modified base system, there seems to be some mismatch between the packager build environment and yours.

For you to know, I will investigate this week another user having an unrelated (and a lot less common) problem on OpenSuSE 10.2, thus I will likely be able to push a working precompiled version your way in a few days if you want me to, provided you are on the same architecture (I am not 100% sure, but I think his is x86).

You're right. I forgot to use the command:

Code:


./configure CFLAGS="$CFLAGS -liconv -L/usr/local/include"

after I applied the patch. I ran that configure command, 'make' and 'make install' again in the same patched source directory and now I get the following error when starting an adesklet:

Code:


Traceback (most recent call last):
  File "./adeskclock.py", line 57, in <module>

I think I'll wait for the package you'll make. Thank you in advance :)

P.S. I'm on an i386 (= 32 bit) architecture (Athlon 1800+) too.

OK -- I will let you know by email in a few days (I might have access to the machine this Thursday).

This said, have you properly uninstalled previous version? And have you used the appropriate --prefix (your configuration line above suggests you didn't check -- most Linux are standardized on --prefix=/usr these days)? Remaining problem is likely as trivial as that... It might not look like it, but to my eyes this is already a progress, since the weird PIL error is gone! Yours,
