I think you meant "relative path" here? I'm not sure if relative names like ../../foo/libbar.so will work with path searches, though. > The only case where a path is needed seems > to be when the lib you want to link to is not in the search path.

Some people just seem to prefer exact paths, while others trust in search mechanisms (and the risk that the wrong library is accidentally picked up). FWIW, I don't mind removing the absolute paths in these scripts, but I was simply interested in what problems people encountered due to them. -Dimitry --Apple-Mail=_61E8D8B5-0D61-4C54-8257-A10FE486E345 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.27 iEYEARECAAYFAlWPyCEACgkQsF6jCi4glqMtmACgw82bQge3+sbYFGOAjmkmaM/t qRkAn1/U0rRiGmJuzI1xEVO5LaqHobMA =aVOv -----END PGP SIGNATURE----- --Apple-Mail=_61E8D8B5-0D61-4C54-8257-A10FE486E345--
