[sane-devel] SANE from darwinports not running under Mac OS X

[Martin Ballaschk]

Hi,

I'm trying to run a Canon LiDE30 (plustek backend) with the help of SANE of
Darwin Ports in Mac OS X 10.4.7.

I installed the following (patched?) packages from Mattias Ellert
(http://www.ellert.se/twain-sane/) into /usr/local/:
* TWAIN-SANE Interface 1.8
* SANE backends 1.0.18-cvs
* libusb 0.1.12

Now I can scan with the help of /usr/local/bin/scanimage and the Image
Capture Utility of Mac OS.

I installed xsane with all its dependencies from DarwinPorts into the
default /opt/local/, to have a more extended GUI. But scanning with
scanimage fails, xsane itself says it could not find any devices. Running
the programs as root does not help, though it could be detected:

$ /opt/local/bin/scanimage
scanimage: no SANE devices found

$ /opt/local/bin/sane-find-scanner
[...]

chip=LM9832/3) at libusb:002:002-04a9-220e-ff-00
[...]

The scanner is plugged in and scanning with Mattias' packages works
flawlessly(!), ist is detected both by sane-find-scanner and scanimage:

device `plustek:libusb:002:002-04a9-220e-ff-00' is a Canon N1240U/LiDE30 USB

How can I run the xscanimage utility ("xsane") under Mac OS X?
I'm not very experienced with Unix and the Shell, so if anyone could provide
help I'd be very thankful.

Cheers,
Martin
