How to use -bloadmap or -bnoquiet option?

Question

I am getting warnings about duplicate symbols during my C compile on AIX 6.1 and it says:

ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.

I have looked up on Google how to use these but no clear answer yet, can someone please tell me what I need to do in order to use -bloadmap or -bnoquiet?

Thanks for the help ;-)

Use either:

xlc -bloadmap:map.file you other paramaters ...

which will generate a map.file which lists where the duplicate symbols come from.

Or:

xlc -bnoquiet you other paramaters ...

which will list the same information to stdout.

Example duplicate information:

 Symbol                    Source-File(Object) OR Import-File{Shared-object}
 ------------------------- -------------------------------------------------
 ...
 .main                     t.c(t2.o)
    ** Duplicate **        t.c(t1.o)

which tells me I have a main function both in t1.o and t2.o.
