From: Andriy Gapon on 8 Apr 2010 04:05 I decided to share this information with the list just in case somebody else uses the functionality and tries to figure out what's wrong with it. -------- Original Message -------- Subject: cupsd vs avahi Date: Thu, 01 Apr 2010 18:51:22 +0300 From: Andriy Gapon <avg(a)icyb.net.ua> To: Dirk Meyer <dinoex(a)FreeBSD.org> Dirk, it seems that currently DNSSD option has no effect in print/cups-base. Event if the option is turned on, configure script fails to configure the support because, as it seems, current net/avahi-libdns doesn't provide sufficient compatibility that cups require. E.g. symbol kDNSServiceFlagsShareConnection is not defined/declared. This is an upstream avahi issue, not of our port. Some links: http://bugs.gentoo.org/293295 https://bugs.launchpad.net/bugs/465916 http://www.cups.org/str.php?L3066 It seems that there is a patch that adds native avahi support to cups and it looks like the patch is used by major Linux distributions at the moment. http://cvs.fedoraproject.org/viewvc/devel/cups/cups-avahi.patch?view=log I tested the patch and it seems to work fine. autoconf has to be run after applying it to regenerate configure script. Thank you for maintaining this beast! ----- End Of Original Message ----- BTW, an update: dnssd backend that gets compiled when the patch is used still doesn't seem to work correctly, it allows to see the printers in some way, but doesn't allow to actually use them. So I had to use perl dnssd backend from here: http://www.openprinting.org/download/printing/dnssd For comparison: output of the included dnssd and output of the perl dnssd in the same environment. Original: DEBUG: Found "hp LaserJet 1320 series (80944D)._pdl-datastream._tcplocal"... DEBUG: Found "hp LaserJet 1320 series (80944D)._printer._tcplocal"... network dnssd://hp%20LaserJet%201320%20series%20(80944D)._pdl-datastream._tcp.local/ "hp hp LaserJet 1320 series" "hp LaserJet 1320 series (80944D)" "MFG:hp;MDL:LaserJet 1320 series" "" network dnssd://hp%20LaserJet%201320%20series%20(80944D)._printer._tcp.local/ "hp hp LaserJet 1320 series" "hp LaserJet 1320 series (80944D)" "MFG:hp;MDL:LaserJet 1320 series" "" Perl: network socket://10.99.0.59 "hp LaserJet 1320 series" "hp LaserJet 1320 series 10.99.0.59" "MDL:hp LaserJet 1320 series;DES:hp LaserJet 1320 series;CMD:POSTSCRIPT,PCL;CLS:PRINTER;" So the perl one reports only one URL for the printer (for socket protocol), but it reports it correctly. Original dnssd reports two URLs (for socket and for lpd protocols), but those dnssd:// URLs seem to be unusable for CUPS to do actual printing. -- Andriy Gapon _______________________________________________ freebsd-ports(a)freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscribe(a)freebsd.org" |
