[Strace][Embedded] How to trace binary error

Using strace to trace

For example:
When I trace smbd by using strace.
Error log : strace smbd > /tmp/smbd.strace.txt
Full log : strace smbd 2&> /tmp/smbd.strace.txt

The log will like below. This log only have error log.

[1970/01/01 13:32:23,  0] ../source3/smbd/server.c:1213(main)
  error opening config file '/home/freeman/test/Samba/EMBED/samba/OBJ/SAMBA_OBJ/etc/smb.conf'

According this log I can debug binary file why can’t execute it.

The error message display server.c:1213 have error. So I can jump to server.c:1213, and see what happen about this place.
Maybe I can fix this bug by myself for embedded system.
