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). SCSI-scanners: -------------- There is support for SCSI 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. sane-find-scanner is not able to find SCSI scanners on MacOS X yet. USB-scanners: ------------- Work with libusb. Very limited testing until now. Try "sane-find-scanner -v -v" and report success or failure to the SANE mailing list. Backends that use fork to create separate reader processes seem to fail. At least the following scanners are known to work: UMax Astra 1220U and 2000U, Epson Perfection 1640SU and 2450 Photo. 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. 2003-06-12 Henning Meier-Geinitz
