<p>Hello,</p>
<p>quite a surprise that someone is trying to use this module, I was
considering to move it to obsolete repo, because nobody used it
for so long and no developer updated it over the time.</p>
<p>The module was still compiling due to some casts, but the DB API
was changed in the past and this module was left behind.</p>
<p>I did the update of the API (still some warnings that needs to be
taken care), so you can try now with master branch. Maybe it goes
on pretty well.<br>
</p>
<p>Otherwise I do not have to test or maintain the module, if you
want to use it, you have to spend some time with it. I can help
fixing bugs when they are obvious in the C code (like API changes)
or a proper report is filled, but that's all I can do.<br>
</p>
Cheers,<br>

<div>Hi,<br>

</div>
<div>I am trying to load db_perlvdb.so module using latest
Kamailio branch v5.0.6 with git revision
49bd81ad7856dac9b2efd53597fb1c<wbr>182de7440b on Debian
Wheezy 32bit. The compilation and installation went
successful however the module gives following error.<br>

I tried to find module perl.so in modules folder of
kamailio installation but there is none. Then i looked
through the source code but no success.<br>
<br>
</div>
<div>After some googling, i found following link which
states that perl.so was remained to app_perl.so since
v4.x.<br>
<br>
</div>
<div>I have created a small patch for db_perlvdb.c which
corrects this error.<br>
