[Ekiga-devel-list] Unnecessary linked libraries

[Eugen Dedu <Eugen Dedu pu-pm univ-fcomte fr>]

Hi,

During building debian packages of ekiga, ptlib and opal, I receive many 
warnings about libraries linked uselessly.  Can these libraries be 
removed from the list of linked libraries?  I imagine however that they 
are needed for certain parameteres to configure, so if it is to 
complicated, let's stay with the actual code.  I think (so not sure) 
that this might have negative influences to entering in debian testing 
of these packages: imagine that libz does not enter testing, this then 
prevents ekiga to enter testing, because its executable erroneously 
depends on it...

Here are the warnings:
