Application with shared library problem in linux

i have created two small programs, one which build as application and another as library. my application program passes parameter to the library then the library performs necessary operations then return the result. this works fine. now here's my problem, i have updated the library (so i recompiled the library) then replace the existing one, then run again my application(without recompiling) -- this still loads the existing one which i expect should load the newly compiled library(on windows this works fine). now, i tried to recompile my application, in this case it loads the new library.

how can i update my library without recompiling my main application?:confused: in my case, the changes only occurs in the library so there's no need to recompile the main application..

thank you very much..
