Fw: Query about GNU-GPL

[Alfred M. Szmidt]

   The question is, what happens if i use also an GPLed lib in the
   same program were i don't have the copyright?  Than i can't give a
   special permission for the GPLed lib. So if linking a program with
   two libs creates a derivated work of each other, than i can't do it
   until i have a permission form the copyright holder of the GPLed
   lib.

Correct, or license your program under the GPL or a GPL compatible
license.  For example, GNU Readline (a GPLed library) can't be used by
non-free programs.
