Re: [SR-Users] Problem adding json module

Hello,

you can go in the source tree, inside json module directory and do:

make proper make Q=0

and see what libs are linked by gcc/ld.

Could have been some duplicate lib installation.

Cheers, Daniel

Hi,

Updating… So I just reinstalled the kamailio’s debian package (apt-get install kamailio, but not the “kamailio-json-modules” one) and the problem was solved (!).

Could not really understood why - when I recheck the libjson-c.so.2 it is still only available on /usr/local/lib.

So maybe there was another linked obj that was only installed by doing this debian package installation.

Thanks,

Joao

Hi Matthew&Daniel

I’ve installed json-c 0.11 instead and I don’t get any more the initial link problems. However when I start the config file I have now this error:

ERROR: <core> [sr_module.c:574]: load_module(): could not open module </usr/local/lib64/kamailio/modules/json.so>: libjson-c.so.2: cannot open shared object file: No such file or directory 0(25993)

I’ve double checked and the libjson-c.so.2 file is there (/usr/local/lib).

Any hints of what could be going wrong here? Do I need to copy it to any other directory?

Thanks!

Joao

Hello,

I haven't written the json module, so I don't know the limits of the versions.

Anyhow, what you can do is to look at debian/rpm specs in source tree at pkg/kamailio/..., there should list the dependencies of the json libs with versions.

jansson is using another underlying library, one of its features being support for json-path.

Cheers, Daniel

Hi Daniel,



I’ve installed the latest release (0.12), but can downgrade if
needed.   which version have you integrated with?



About jansson, I was not really aware of it. is it providing
improved functionalities compared with json?



Thanks,

Joao

Hello,

what is the version of the json library? Maybe they changed the
api in a new version.

We have to fix the one for json, but note that you may use jansson
module for json handling in config file.

Cheers,
Daniel

    Hi,



    Have just installed the kamailio 4.3 (from github) and was
    trying to include the additional modules that I require. I’ve
    edited the modules.lst and changed the extra modules to
     compile “include_modules= db_mysql utils json”.



    During compilation (using “make all”) getting the following
    warnings in relation with the json module.



    CC (gcc) [M json.so]                json_funcs.o

    json_funcs.c: In function 'json_get_field':

    json_funcs.c:58:2: warning: implicit declaration of function

    deprecated (declared at
    /usr/local/include/json-c/json_object.h:303)
    [-Wdeprecated-declarations]

    And later, when running the config file:



    ERROR: <core> [sr_module.c:574]: load_module(): could not open
    module </usr/local/lib64/kamailio/modules/json.so>:

    /usr/local/etc/kamailio/kamailio.cfg, line 195, column 12-20:
    failed to load module ERROR: bad config file (1 errors)



    I have already installed json-c modules and confirmed this
    installation by doing:



    root@ID14337:/usr/local/kamailio-4.3/kamailio#
    <mailto:root@ID14337:/usr/local/kamailio-4.3/kamailio>
    pkg-config --cflags json-c

    -I/usr/local/include/json-c 

    root@ID14337:/usr/local/kamailio-4.3/kamailio#
    <mailto:root@ID14337:/usr/local/kamailio-4.3/kamailio>
    pkg-config --libs json-c

    -L/usr/local/lib -ljson-c 



    root@ID14337:/usr/local/include/json-c# ls

    arraylist.h  json.h                    json_inttypes.h        
           json_object_private.h  linkhash.h

    bits.h          json_c_version.h  json_object.h         
           json_tokener.h               printbuf.h

    debug.h      json_config.h     json_object_iterator.h 
    json_util.h        random_seed.h

    root@ID14337:/usr/local/include/json-c# cd ../../lib

    root@ID14337:/usr/local/lib# ls

    libjson-c.a  libjson-c.la  libjson-c.so  libjson-c.so.3 
    libjson-c.so.3.0.0  pkgconfig    python2.6  python2.7

    root@ID14337:/usr/local/lib#



    So any ideas of what could be causing this to fail?



    Thanks
