Yes , I am doing some work about fujitsu scanner~~. ^_^.
I have made a symlink as you say: ln -sf libsane-khf.so.1 libsane-khf.so.
And then type ' strace scanimage -L' . I got the following output ( a piece of
output):
open("/usr/lib/sane/libsane-khf.so.1", O_RDONLY) = 3
close(3) = 0
open("/usr/lib/sane/libsane-khf.so.1", O_RDONLY) = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\00002\0\000"..., 512) = 5
12
fstat64(3, {st_mode=S_IFREG|0744, st_size=106088, ...}) = 0
old_mmap(NULL, 104040, PROT_READ|PROT_EXEC, MAP_PRIVATE, 3, 0) = 0x4019f000
old_mmap(0x401b5000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED, 3, 0x150
00) = 0x401b5000
old_mmap(0x401b7000, 5736, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_FIXED|MAP_ANONY
MOUS, -1, 0) = 0x401b7000
close(3) = 0
fstat64(1, {st_mode=S_IFCHR|0600, st_rdev=makedev(136, 2), ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0 x401b9000
write(1, "\n", 1
) = 1
And I still can't see my tips in sane_init.( I wrote "printf("sane_init
\n");" at the first in sane_init code). Is there any steps I missed?? Thanks a
lot~~
