Here's an example of dumping the symbols from an object file (hello world in foo.c -> foo.o):

me@mine:~$ objdump -t foo.o

SYMBOL TABLE:
00000000 l df *ABS* 00000000 foo.c
00000000 l d .text 00000000 .text
00000000 l d .data 00000000 .data
00000000 l d .bss 00000000 .bss
00000000 l d .rodata 00000000 .rodata
00000000 l d .note.GNU-stack 00000000 .note.GNU-stack
00000000 l d .comment 00000000 .comment
00000000 g F .text 00000026 main
00000000 *UND* 00000000 puts

A byte offset from the beginning of the archive to the member's header. The archive member residing at the given offset defines the associated symbol. Values in may be passed as arguments to to access the desired archive member. A hash value for the name, as computed by If ptr is non-null, the library stores the number of table entries in the location to which ptr points. This value is set to zero when the return value is null. The table's last entry, which is included in the count, has a null a zero value for and for SEE ALSO
