Re: wrapit with xlf

Dear Mary,

I am very interested in generating the shared objects by hand. So I
try on my Mac.

I have finished step 1 to step 3.
when I did step 4, I met some problem. It said:
ld: Undefined symbols:
_NclGetArgValue
_NclRegisterFunc
_NclRegisterProc
_NclReturnValue
_NewArgs
_NhlPError
_SetArgTemplate
dyld_stub_binding_helper
_do_lio
_e_wsle
_s_stop
_s_wsle
_sqrt

As you mentioned, this is hardest part for getting right option. I
did not put any option.
Now I have a question. All these undefined symbols are functions. Do
you know where they are?
So I can link them.

Thanks
Guangshan
