When dlopen() encounters a bad library (e.g. wrong arch), it will just continue on and find another library. lt_dlopen() however, will stop on the first library which it can read. This breaks libltdl applications horribly in multi-arch environments. As LD_LIBRARY_PATH is not arch specific, having a universal one means having one like: LD_LIBRARY_PATH=3D/usr/foo/lib32:/usr/foo/lib64 This works fine with dlopen(), but not with lt_dlopen(). The fix seems simple enough. In find_handle_callback(), change: *phandle =3D 0; to: return 0; Rgds --=20 Pierre Ossman OpenSource-based Thin Client Technology System Developer Telephone: +46-13-21 46 00 Cendio AB Web: http://www.cendio.com --=_freyr.ossman.eu-6041-1346412650-0001-2 Content-Type: application/pgp-signature; name="signature.asc" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) iF4EAREIAAYFAlBAoGkACgkQopDLsoqlmELZWQD/YMMqn4WdFuuHOCiWyuJEPlqs M41TMntwrfNWdzmrQq8A/R1mUfqMGskCWYCMkTcvwpRQE18pG+jUuZR9vEF7PV69 =DRtB -----END PGP SIGNATURE----- --=_freyr.ossman.eu-6041-1346412650-0001-2--
