Re: [Hp5400backend-devel] unable to find 'some functions'

[Thomas S. <sou...@ne...>]

The problem is known here.

When we built this first revision of the h0p5400 backend, we could only try=
 it=20
on few scanners that all gave a similar answer to "what is your revision"=20
question. So we decided to add a test to see if revision match so that we g=
et=20
more sure the backend works with the scanner.

To avoid this test, you have to recompile the sane backends, adding=20

 #define NO_STRING_VERSION_MATCH

at the beginning of hp5400.c file.
Then recompile, install and that should be ok.

Note that it worked for some people, but it is still "at your own risk". Fo=
r=20
the first tries, be near the scanner, ready to unplug it if it makes strang=
e=20
noises.

Have a nice day,

Thomas
