cat debian/libflac++6.symbols | c++filt | sed -e 's/^ / (c++)"/' -e 's/@/"/' But, as James mentions, there is still manual work to do: replace all types by their original typedef, in case the definition differs in different architectures. -- Saludos, Felipe Sateler -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe".
