[fpc-pascal]Linking problem

[Kassai Istvan]

Hello!

I'm sure this isn't a big problem, but I can't compile any  example 
programs eg. postgres and mysql related ones.

If I'm trying to compile the testpg1.pp (from examples) the linker gives 
this message. What does it mean, and what can I do to eliminate it?
---------------------------------------

Assembling testpg
Linking testpg1
/usr/bin/ld: cannot find -lpq
testpg1.pp(106,7) Error: Error while linking
Closing script ppas.sh
----------------------------------------

And if I want to compile the mysql sample, the message is the next:
----------------------------------------
Assembling qtest
Linking testdb
/usr/bin/ld: cannot find -lmysqlclient
testdb.pp(84,3) Error: Error while linking

What have I set up yet????


thanks, bye
