Debugging cups issues is always difficult. FWIW, I've got 1.5.3, 5.2.7, 9.05 on my latest build. Hadn't got around to testing it (so many other issues :) but I've now successfully printed the test page and a photo. My own builds of cups have become very different from what ended up in the book (I think it was the change to 1.5 - I went one way, the book went another), but this is how I'm configuring : ./configure \ --enable-threads --enable-gnutls \ --with-pdftops=/usr/bin/pdftops followed by a straight make and make install. I'm not sure why I had to specify the pdftops location - it comes from poppler. Ah, yes, I remember : I build cups before gtk2 (so that the print queues will be available to gtk2 applications), but the rest of the printing stack, including poppler, is built much later. I'm using an epson usb printer, and I do *not* install libusb. You should perhaps also check that everything below /usr/lib/cups is owned by root:root, and /var/spool/cups/ is owned by root:lp. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
