|
</EM><BR>
|
|
<EM>> the new backend from my site.
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> I would do it this way:
|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> - install source RPM
|
|
</EM><BR>
|
|
<EM>> - build the sytem once using the rpm -ba <path_to_sane_spec_file>
|
|
</EM><BR>
|
|
<EM>> - go to /usr/src/package/BUILD/sane-.../backends and replace the
|
|
</EM><BR>
|
|
<EM>> epson.c and epson.h files with the ones from the from my web site

|
|
</EM><BR>
|
|
<EM>>
|
|
</EM><BR>
|
|
<EM>> Then just do a make in the backends directory. This will rebuild
|
|
</EM><BR>
|
|
<EM>> just the EPSON backend. You can find the new one in the .libs directory.
|
|
</EM><BR>
|
|
<EM>> Just copy the file .libs/libsane-epson.so.1.0.4 to the Sane library
|
|
</EM><BR>
|
|
<EM>> directory (probably /usr/lib/sane).
