hi,all

(gdb 5.0 sparc solaris 8)

I have a library link by sun cc,this library is complied and link
with flag -g.

I try to find out the prototype of functions in this library,gdb output:
(gdb) p GetDatVersion
$1 = {<text variable, no debug info>} 0xff273374 <GetDatVersion>
(gdb) p GetDatVersion
type = int ()

Does the library must complied by gcc?

Thanks.

regards
