Using functions from other shared library in UDF

Hello,

I'm new to UDF and MySQL :-).

I faced the following problem:

I created UDF and compiled to so library (under Linux).
My UDF calls functions from the other shared object (librpm.so).

When issuing 'CREATE FUNCTION' with my UDF it returns:
'undefined symbol' for any function from librpm.so called in my UDF.

Is there a way how to make MySQL load the other .so as well and make it works?

What I checked:

1) I tried make librpm.a (static archive) from librpm.so - could not. I don't have sources to this. Also I could not found package with librpm.a.
2) I put librpm.so to MySQL plugin directory - didn't help.
3) I tried: install soname 'librpm'; Ir returned: Can't find symbol '_mysql_plugin_interface_version_' in library.

For now I don't have idea hw to resolve it,

Thanks for help in advance,
Marcin Dzieszko
