SANE and Darwin (Mac OS X) -------------------------- Building: --------- You may get the message: "gcc: Internal compiler error: program cc1obj got fatal signal 11". 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
