Hi Panvan,

It seems you have built that "dict_dcca_3gpp.fdx" module by yourself, 
since it's installed under "/usr/local/lib", so maybe the issue is 
related to your build/install and usage process. What we know:

* the "fd_g_config" variable is located in the "libfdcore" shared 
library (provided by "libfdcore6" package on Debian 10)
* the "freeDiameterd" daemon *depends* on the "libfdcore" library, 
otherwise it won't start

So if you get the "fd_g_config missing symbol" error, it means the 
libfdcore library failed to load, or it wasn't located.  Maybe you 
should try creating a "/etc/ld.so.conf.d/freeDiameter.conf" file with 
the "/usr/local/lib/" or whatever library path you build & installed the 
"libfdcore.so" file, then hit "sudo ldconfig", so your loader knows 
*where *to load your development library from!

But even simpler:  why not just work on a Debian 10 VM, which comes with 
nice packaging, including the extension you need:

# dpkg -L freediameter-extensions | grep fdx
/usr/lib/freeDiameter/acl_wl.fdx
/usr/lib/freeDiameter/dbg_monitor.fdx
/usr/lib/freeDiameter/dbg_msg_dumps.fdx
/usr/lib/freeDiameter/dbg_msg_timings.fdx
/usr/lib/freeDiameter/dbg_rt.fdx
/usr/lib/freeDiameter/dict_dcca.fdx
*/usr/lib/freeDiameter/dict_dcca_3gpp.fdx*
/usr/lib/freeDiameter/dict_dcca_starent.fdx
/usr/lib/freeDiameter/dict_eap.fdx
/usr/lib/freeDiameter/dict_mip6a.fdx
/usr/lib/freeDiameter/dict_mip6i.fdx
/usr/lib/freeDiameter/dict_nas_mipv6.fdx
/usr/lib/freeDiameter/dict_nasreq.fdx
/usr/lib/freeDiameter/dict_rfc5777.fdx
/usr/lib/freeDiameter/dict_sip.fdx
/usr/lib/freeDiameter/rt_busypeers.fdx
/usr/lib/freeDiameter/rt_default.fdx
/usr/lib/freeDiameter/rt_ignore_dh.fdx
/usr/lib/freeDiameter/rt_load_balance.fdx
/usr/lib/freeDiameter/rt_randomize.fdx
/usr/lib/freeDiameter/rt_redirect.fdx

In this package-based setup, you would only need the "freeDiameter/" 
source code in order to build the "app_opensips.fdx" extension to go 
with the other extensions installed by packages!  Of course, the source 
code version must be 1.2.1 (follow the freeDiameter Tutorial 
<https://www.opensips.org/Documentation/Tutorials-Diameter-AAA> and you 
should be good!)

Best regards,
