Looking back at the thread started by Rafe about installing and then
getting the latest version to be the version used....<br>
<br>
I think we may need to update some advice pages, and perhaps some
sane documentation? In particular this page:<br>
<blockquote><a class="moz-txt-link-freetext" href="https://help.ubuntu.com/community/CompileSaneFromSource">https://help.ubuntu.com/community/CompileSaneFromSource</a><br>
</blockquote>
says Discover where your existing sane is installed :<br>
<br>
sudo find /usr/lib -name 'libsane-dll.so'<big><br>
</big>
<pre>
<big>But this did not work for Rafe, and does not now work for me on my ubuntu 14.10</big>
<big>Now it seems that
find /usr -name 'libsane.s*'
Will detect existing sane installations. But is that the best distro independent way to detect them?
(And is the file libsane-dll.so part of a sane installation anymore?)
Also in
<a class="moz-txt-link-freetext" href="https://help.ubuntu.com/community/CompileSaneFromSource">https://help.ubuntu.com/community/CompileSaneFromSource</a>
There is advice on switching between versions of sane which says to edit <small>/etc/ld.so.conf</small></big></pre>
<blockquote>To use the old version it should read <br>
include /etc/ld.so.conf.d/*.conf
<br>
<span class="anchor" id="line-2-6"></span>include /usr/lib<span
class="anchor" id="line-146"></span><span class="anchor"
id="line-147"></span>
<p class="line874">To use the new version, change it to<big><br>
</big>include /etc/ld.so.conf.d/*.conf
<span class="anchor" id="line-2-7"></span><br>
include /usr/local/lib<span class="anchor" id="line-152"></span><span
class="anchor" id="line-153"></span></p>
<p class="line874">Then run sudo ldconfig <small><big>and
you should be running the latest sane. </big><br>
</small></p>
</blockquote>
<p class="line874">Now that seems very oversimplified because the
many *.conf files in<br>
/etc/ld.so.conf.d/<big><br>
</big>Can point to where sane is.<br>
I don't think I understand all this enough to give reliable
advice, particularly for distros other than the one I am using.<br>
</p>
<p class="line874">Does anyone have ideas about how we should in
general:<br>
Detect all existing sane installations.<br>
Advise what parameters to give to ./configure<br>
Advise how to switch between multiple installations.<br>
