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. Very limited testing until now. 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.
|
|
|
|
There are some known problems with libusb:
|
|
|
|
- Older libusb versions return the wrong number of bytes written. Most backends
|
|
will return an error and won't work. Update your version of libusb.
|
|
|
|
- Set configuration doesn't reclaim the interface. This is important for the
|
|
sm3600 backend.
|
|
|
|
- Libusb sets only the completion timeouts, but not the no data timeouts.
|
|
|
|
A patch for these problems is available at
|
|
https://sourceforge.net/tracker/?group_id=1674 request ID 1044204
|
|
|
|
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.
