If you want to you can download the MrSid SDK and uncompress the
sids on your linux workstation:
<a href="http://www.lizardtech.com/downloads/category/" target="_blank">http://www.lizardtech.com/downloads/category/</a> (MrSID SDK)<br>
<br>
I downloaded the SDK (placed it in /home/rjhale/apps and wrote a
very small messy script that does the following: <br>
#!/bin/bash<br>
<br>
#set library path<br>
export LD_LIBRARY_PATH=/home/rjhale/apps/sidgeodecode/bin<br>
<br>
#fix the extension<br>
file=$1<br>
newname=`echo $file | sed 's/\(.*\.\)sid/\1tif/'` <br>
<br>
#run the Geodecode program<br>
/home/rjhale/apps/sidgeodecode/bin/mrsidgeodecode -wf -i $file -o
$newname<br>
<br>
It usually takes just a minute or two to uncompress them on my
workstation - for me a sid that is 400 mb usually uncompresses to 6
GB - with a small amount of work (tiling, pyramid layers) it's
renders very nicely. <br>
<br>
I agree - building sid support into QGIS is not for the faint of
heart. I did it once but decided against - I would rather just
uncompress them using this route and be done with it. <br>

<div>Dears, I guess the message title is explicit enough ?<br>
<br>
<br>
BTW, I have downloaded the SDK 9.1.0 from Imtech. The
ReadMe says:<br>
<br>
"INSTALLATION:<br>
<br>
No specific installation is required to use the MrSID SDK
beyond copying the SDK contents to your local machine.<br>
<br>
After installing, we suggest building and running the
example program to assure correct installation and
behaviour."<br>
</div>
<div><br>
<br>
But copying the SDK download (unpacked) somewhere on my disk
obviously is not enough and I am lost when it comes to
"building" etc.<br>
<br>
</div>
<div>Thanks,<br>
<br>

<div>As far as I know, there is no way, but building your own gdal
with mrsid support und Linux. The instructions can be found
somewhere in the qgis-maze, but I don't how up-to-date they are.</div>
<div>I tried once, but as the instructions were not really
idiot-proof and I prefer to use repositories, and as there was
no clear instruction to be found how to deal with
incompatibilities, I gave up so far. </div>
<div><br>
</div>
<div>I think the masterbrains just compile everything, and the
stupid masses use a virtual Windows machine to transform to
geoTIFF (like me).</div>
<div><br>
</div>
<div>There was an article mentioned in the list how to produce
quite small geoTIFF some weeks ago:
