See those *UND* bfd_foo symbols? bfd_init and friends? Those are defined
by libbfd. Here's an example program:
$ cat opagenttest.c
char op_open_agent ();
int
main ()
{
return op_open_agent ();
;
return 0;
}
$ gcc opagenttest.c -L/usr/lib/oprofile -lopagent -o opagenttest
/usr/lib/oprofile/libopagent.so: undefined reference to `bfd_check_format'
/usr/lib/oprofile/libopagent.so: undefined reference to `bfd_init'
/usr/lib/oprofile/libopagent.so: undefined reference to `bfd_openr'
/usr/lib/oprofile/libopagent.so: undefined reference to `bfd_perror'
/usr/lib/oprofile/libopagent.so: undefined reference to `bfd_get_mach'
/usr/lib/oprofile/libopagent.so: undefined reference to `bfd_get_arch'
collect2: ld returned 1 exit status
$
Please statically link libbfd into libopagent.so.
Thanks,
Nick Lewycky
