How you compile your library?
I still have the same problem: on my module file everything goes fine,
but on my core app file no API function are added to .dynsym table
(the ones to be used by modules). Using you script i cannot get
modules to access some funtions on core side, they only are added to
.symtab table.
thanks once again!!!
