Created attachment 542778 [details] Ebuild Hi! Please find attached scangearmp2-3.50.ebuild and a patch so that it will compile on modern systems (and, additionally, won't crash on runtime). Scangear MP is a scanning tool supplied by Canon, for use with its multi-function printer/scanner combo units. Sadly these scanners don't work with SANE, so the easiest option is to use this utility. It supports scanning from the platen (flatbed) or from an automatic document feeder. This ebuild has no other dependencies that aren't already in the Portage tree. Marc van der Wal

Created attachment 542798 [details, diff] Patch that fixes a crash due to an uninitialized pointer This version of the patch only makes the absolute necessary changes to the code in order to prevent it from crashing.
I think this package is very interesting for the main tree. Could you add to the longdescription, which printers are supported? LICENSE="Canon-IJ" Have to check, which RESTRICT= is required. Licenses Team can help. Is SRC_URI="http://gdlp01.c-wss.com/gds/3/0100009113/01/${MY_P}.tar.gz" reliable, or is it likely to change soon? HOMEPAGE="https://www.canon.com" Is there a more specific homepage?

That's true, but we neither modify the software nor distribute a modified version. We would distribute a (trivial) patch along with it, to be applied on users' systems only for their own use. RESTRICT="bindist" will be needed, though. Disclaimer: IANAL, TINLA.

By grepping the udev rules file that they install (which matches printers by their USB IDs), I get the following list: E3100 series E460 series E470 series E480 series G3000 series G4000 series MB2000 series MB2100 series MB2300 series MB2700 series MB5000 series MB5100 series MB5300 series MB5400 series MG2900 series MG3000 series MG3600 series MG5600 series MG5700 series MG6600 series MG6800 series MG6900 series MG7500 series MG7700 series MX490 series TR7500 series TR7530 series TR8500 series TR8530 series TR8580 series TS3100 series TS5000 series TS5100 series TS6000 series TS6100 series TS6130 series TS6180 series TS8000 series TS8100 series TS8130 series TS8180 series TS9000 series TS9100 series TS9180 series XK50 series XK70 series My Canon TR8550 printer is oddly enough missing from this list, even though I downloaded the software from the printer model’s support page. I haven’t tested it with USB but I can confirm that scanning through the network works like a charm. > Is SRC_URI="http://gdlp01.c-wss.com/gds/3/0100009113/01/${MY_P}.tar.gz" > reliable, or is it likely to change soon? It’s the same URL structure as for net-print/cnijfilter (which is the print driver for these units) and I haven’t experienced any problems with that package. Only the “0100009113” part might change between versions and there is no predictable way to “guess” that URL component. > HOMEPAGE="https://www.canon.com" > Is there a more specific homepage? Sadly, I don’t think there is. They don’t seem to offer the download from elsewhere than from their support page. To get to the software, you need to select your specific printer model and get to the driver download page. Also, there are multiple Canon support websites, one for each country.

To be honest, I haven’t gotten in touch with Canon yet but I was considering to report the bug (and submit the patch) to them, hoping that eventually we won’t need to resort to patching it ourselves. Obviously I wish they had test-compiled their software with CFLAGS="-Wall" and without CFLAGS="-g". I see that net-print/cnijfilter, which is distributed under the same license terms, also has a patch, although it fixes the build system.
Hi. Is it likely that this ebuild will graduate to be a part of portage?
