You need to link against libpq when you link the asterisk binary (the
gcc -o / ld stage), e.g. -lpq.

Hi
I have created an asterisk module in c called app_callingcard.c. In my
app, I am connecting to a postgresql database using #include
<libpq-fe.h> library. I have been using this app in version 1.4 for
couple years now without any problems.
I recently upgraded to asterisk version 1.6.1 and have made the
necessary changes to my app so that its compatible with version 1.6.1.
I am able to compile my app in version 1.6.1 with no error messages and
it creates an app_callingcard.so file in asterisk's module folder.
The problem arises when I try to load my app within asterisk "module
load app_callingcard.so". I get the following error message:
WARNING[31732]: loader.c:417 load_dynamic_module: Error loading module
'app_callingcard.so': /usr/lib/asterisk/modules/app_
callingcard.so: undefined symbol: PQsetdbLogin.
How could that be when PQsetdbLogin is part of libpq-fe.h and asterisk
is able to compile it without any problems, but is not able to load it
using loader.c?

You need to link against libpq when you link the asterisk binary (the
gcc -o / ld stage), e.g. -lpq.
And the way to do this is to place the following comment within your C source
file:
/*** MODULEINFO
<depend>pgsql</depend>
***/

Thanks everyone for your help. I did add the following to my code, but I am still getting the exact error message. I also made sure I deleted my old module and made sure the new module that was created is the one with <depend>pgsql</depend>.

Is there something else that I am doing wrong?
Do you build your module in the Asterisk tree or outside of it? The
MODULEINFO section is used by the Asterisk build system when you build a
module in the tree.

I do the build of my module in Asterisk tree. The module is in the asterisk source apps folder. I run make, then make install and the module compiles perfectly without any errors.

After no success with everything I tried, I downgraded to asterisk 1.4.25 and went back to my original code which worked perfectly on asterisk 1.4.21. However, I am getting the same undefined symbol: PQsetdbLogin error in 1.4.25. What I forgot to mention though, is that the module that is working in asterisk 1.4.21 is running on a different server. Below are the specs for both servers:
Server with asterisk 1.4.21 with my asterisk c module running perfectly:
model name : Intel(R) Pentium(R) 4 CPU 3.00GHz
processor : 2
cpu MHz : 3 Ghz
Operating System: Fedora Core 5
Server with asterisk 1.4.25/1.6.1 that gives me undefined symbol: PQsetdbLogin when I tried to load the module in asterisk. This happens even though I include <depend>pgsql</depend> in the MODULEINFO in my source code.
model name : Dual-Core AMD Opteron(tm) Processor 1216 HE
processor : 2
cpu MHz : 2.2 Ghz
cpu cores : 2
clflush size : 64
cache_alignment : 64
Operating System: Centos 5 (64 bit)
I hope this information will shed some more light into my problem.
Thanks everyone.

Was anyone able to figure out what I might be doing wrong on my end?
