dlopen from dlopend library question

[Gleb Natapov]

Hello,

Not sure this is the right place to ask, but anyway...

I have library (lets say liba.so) that on startup checks available 
hardware and loads appropriate plugin (say plugin.so) to drive the hardware.
plugin.so uses symbols from liba.so. 

Everything works OK if liba.so linked with application, but if
application is modular by itself and use module (say module.so) that
is linked with liba.so then dlopen of plugin.so from liba.so fails with
unresolved symbols.

How can I solve this issue?

PS: All this happens using linux system.

Thanks in advance,
