In the distant past, there was a www/linuxpluginwrapper port that supported this (I used it with print/pips-scx3500_3600s to print to an Epson inkjet print using a Linux blob). Unfortunately, www/linuxpluginwrapper didn't support ELF symbol versioning and was "replaced" with www/nspluginwrapper, which dropped all the required functionality. https://lists.freebsd.org/pipermail/freebsd-ports/2008-June/048827.html describes my last efforts to get that approach to work. I don't know if that's of any use to your efforts. --=20 Peter Jeremy --rqzD5py0kzyFAOWN Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQKTBAEBCgB9FiEE7rKYbDBnHnTmXCJ+FqWXoOSiCzQFAl3XoGtfFIAAAAAALgAo aXNzdWVyLWZwckBub3RhdGlvbnMub3BlbnBncC5maWZ0aGhvcnNlbWFuLm5ldEVF QjI5ODZDMzA2NzFFNzRFNjVDMjI3RTE2QTU5N0EwRTRBMjBCMzQACgkQFqWXoOSi CzRL6xAAkzDqTI9I3pc5ztyOI6pONIKY169U3Q0VsPt5rMmkPlCc+jTw+MvXvAew wd+EpZLR4Qbxesk33wv2AwcsrjYqzCquXdWINI55Jt0cD92iWGAD440IKpAOmo0x NaAVAWvpoMDP22aoI/1JcdlbSA9mDpByNorDxsAOiIhD8r90FJ/HSl9fcpmiBEJE j2NA+CK3PgtaPwv4rkR9vBkewbwuNIVwgtJ+3CSbvHzLeARJZMv1dYlP4UMUFLPr RKxNSyk+mwHSdCPU1Ga1K5f116QBka8C2BQbsG1/hVyvXzqecnCunejE4GXiIdB0 Sg5QvpGeYSbGpEeKh8RgdJOrjPKgc1HecvbTjlLOTJgItfDTueD6d9q6ttkPfdOO 63shhrrexrgrEE3N5pmCmOiXJTHBmHEGbK6oiHlwQvZ69XSdiQC8nFJj//MmEwtb qEONOYifHpMw8U0+0fup14REb+q5x7uOKjeFu3xxiO0sZ3ik+arAPK0SvVrSUQgU n/6bSzCCEJD268zVVlJt7Oyju6S9FRg8ds6eiuJztWYCYEjrfK5JkuO8jN1Ebfuv 12bEiKcgEnDEfVfUuHMDRvfCZQ5WayCtPNLL8PTRyqbOuZln8i3ZVWmWFXHu5qV8 aaPJe5Q5S5JojN+Synw3DEfijD1A3oFkhB0ncpx6TbRIdOQklt0= =Fl4h -----END PGP SIGNATURE----- --rqzD5py0kzyFAOWN--
