profiling shared libraries

[Taha Mannan Jiruwala]

Hi,

I have tried profiling shared libraries using the following:

program=test.c
main()
{
           printf("hello world\n");
}

$ gcc test.c -lc

$ ldd a.out
        libc.so.6 => /lib/libc.so.6 (0x4001a000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)b

$ export LD_PROFILE=/lib/libc.so.6

$ ./a.out

hello world

$ unset LD_PROFILE

$ gprof /lib/libc.so.6 libc.so.6.profile

The versions are
gcc -> egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
gprof ->GNU gprof 2.9.5

Here I am getting the message:
"gprof: file `libc.so.6.profile' has unsupported version 131071 "

Please help me in this regard..

Thanks in advance,
taha
