Hi!<br>
<p>
Is this the right place to send patches?<br>
<p>
<p>
After some minor tweaking I got sane 0.71 up and running on both<br>
FreeBSD 2.2.5 and FreeBSD 3.0 (-CURRENT).<br>
<p>
I'm using an Agfa Snapscan 310.  No idea how other backends may fare,<br>
but I see no reason why they should not work too.<br>
<p>
<p>
Now for the bad <a href="news:">news:</a><br>
<p>
So far xscanimage does not work well (for me) as a gimp-plugin (does<br>
not work with colour images, not even with the pnm backend).  Is<br>
anyone successfully using gimp-0.99.18 + gtk-0.99.3 + sane-0.71?<br>
<p>
If I get the time, I'll build everything on a Sparc/Solaris and see if<br>
the same thing happens there, to rule out platform weirdness.  Then<br>
maybe I'll see what "Purify" has to say... (the number of gimp<br>
warnings printed out is slightly unsettling...)<br>
<p>
NOTE: the configure script will leave out gimp support entirely if<br>
"&lt;libgimp/gimp.h&gt;" is not in the regular compiler search path.<br>
Using CPPFLAGS in environment when running configure is one workaround<br>
(e.g. configuring with "CPPFLAGS=-I/usr/X11R6/include ./configure")<br>
<p>
Summary:<br>
<p>
     Platform: FreeBSD 2.2.5, FreeBSD 3.0<br>
     SANE version tested: 0.71 (Gtk 0.99.3, Gimp 0.99.18)<br>
     Compiler: Gcc<br>
     User-level SCSI support: yes<br>
     Shared library support: yes<br>
     Dynamic loading support: yes<br>
     X11 clients: yes (have not tested xcam)<br>
     GIMP support: yes, thouhg it seems to need some debugging<br>
<p>
<p>
<p>
       Regards,<br>
       /Mikko<br>

FreeBSD Patches (diffs for sane-0.71):<br>
<p>
If you are the trusting type, simply go to the sane-0.71 distribution<br>
directory and feed the rest of this message to "patch".  If not, read<br>
on (it isn't all that much).<br>
<p>
<p>
Gcc gave up unless I did this (on Solaris too).  Hope it was the right<br>
thing to do:<br>

A bit of a moot point -- anyone who has gotten around configuring the<br>
"unknown" scsi devices is likely to already have figured out where the<br>
scanner is.  But I guess it doesn't hurt looking, so:<br>

Libtool kept printing out insults against the system linker, even<br>
though I know for a fact that it is possble to compile, link and<br>

"libsane.so" in the binaries otherwise):<br>

found that it worked:<br>

not - the aic driver doesn't do dma, and the 1505 generates tons of<br>
interrupts, which slows down the system noticeably during scans.<br>

And last, xscanimage got floating exceptions on seemingly normal<br>

similar problems with TCL, I dug up these lines from tcl-7.5:<br>
