Subject: Profiling libraries

I am trying to profile a program which uses zlib1.2.1 i.e. libz.so.1.2.1

As I read on internet, it is easier to get profile data when linked statically.
so I am trying that first.

1st: Just compile source of the lib with -pg option.
     Compile example.c, that comes with zlib , with -pg option
     statically linked the libz.a
     Run the make test, it also executes example and creates gmon.out
     gprof ./example
     It shows all the lib functions in the profile , 
     but timing is 0.00 for all

I wonder why? anybody has solved this before?

thanks 
mrunal
