That's not a bug in SANE. Probably a compiler or hardware +problem. The error usually occurs in canon.c because that's the most complex +backend (at least concerning compilation). If you can't update your compiler, +try to reduce optimization (e.g. CFLAGS="-O1" ./configure). Another +work-around: Disable the canon backend in backend/Makefile.in (look at +PRELOADABLE_BACKENDS) and rerun configure. + +General: +-------- +If scanimage -L (or any other frontend) stops with a segmentation fault in the +sm3600 backend, disable sm3600 in dll.conf if you don't need it. + +Backends that use the function "fork" may not work at least with USB scanners. +That's a limitation of MacOS X (doesn't use file descriptors for USB access). +Most backends have been modified to use threads on MacOS X and should +work. Others don't use fork at all. Both types of backends should work with +MacOS X. Changing the backends to use threads is an ongoing effort. + +SCSI-scanners and Firewire scanners: +------------------------------------ +There is support for SCSI and Firewire scanners but hasn't had much +testing. Please send failure and success reports to the sane-devel mailing +list. At least the Epson Perfection 1640SU and the CANON IX-06015C (CanoScan +600) are reported to work. + +USB-scanners: +------------- +Work with libusb. Try "sane-find-scanner -v -v" and report success or +failure to the SANE mailing list. At least the following scanners are +known to work: UMAX Astra 1220U and 2000U, Epson Perfection 1640SU and +2450 Photo. + +Use libusb version 0.1.11 or later (or a cvs checkout from 2005-09-01 +or later). If you use earlier versions the libusb code needs to be +patched. + +Parport-scanners: +----------------- +I don't have any information about these. Please contact me or the SANE mailing +list if you succeeded in using one of these. + +2003-12-26 Henning Meier-Geinitz +2005-05-07 Mattias Ellert -- cgit v1.2.3
