Hi Nicolas,<br><br>Ok, so indeed, the git version without pthtread works flawlessy (see attached log). However, I so far didn't manage to build sane-backends with pthread. After exactly following your instructions, I get the message below. This is with no ubuntu sane packages installed. Can anybody tell me which dev package I miss to build sane with pthread?<br>

Karmic with the USE_PTHREAD/-lpthread support, which revealed a bug at<br>
end of scan (not produced when pthread support is not activated).<br>
<br>
Just committed a fix, so could you please give a try with git Sane, and<br>
test both compilations options, with and without pthread support.<br>
<br>
You can follow the guidelines here to compile and install Sane:<br>
<a href="http://mp610.blogspot.com/2008/04/give-your-scanner-new-freshly-sane.html" target="_blank">http://mp610.blogspot.com/2008/04/give-your-scanner-new-freshly-sane.html</a><br>
<br>
- To compile without pthread support, set firstly 2 export lines this:<br>
<br>
make distclean<br>
export CFLAGS=""<br>
export LIBS=""<br>
<br>
Then go on from the ./configure steps<br>
<br>
When you run a scan after activating the log trace (as explained in a<br>
previous mail), you should get in the log trace, a line like this near<br>
the beginning:<br>
<div class="im"><br>
[pixma] Reader task id=xxxx (forked)<br>
<br>
</div>- To compile with pthread support (this is the Ubuntu/Karmic way), set<br>
first 2 export lines this:<br>
<br>
make distclean<br>
export CFLAGS="-DUSE_PTHREAD"<br>
export LIBS="-lpthread"<br>
<br>
Then go on from the ./configure steps<br>
<br>
When you run a scan after activating the log trace, you should get in<br>
the log trace, a line like this near the beginning:<br>
<br>
[pixma] Reader task id=-xxxxxxxxxx (threaded)<br>
<br>
In both cases, hopefully, the multi-page ADF scan should work correctly<br>
now ;-)<br>
<br>
Let us know.<br>
