[gdal-dev] Convert ECW to TIFF

I have a bunch of ecw images that I need to convert to tif+worldfile.

I therefore need to recompile gdal against the ecw libraries, but the 
only file I can download from Intergraph/Erdas website is:
which is a Windows install of the SDK.

How do I do this for Linux?
(Want to batch convert them on ubuntu 10.04)

On another note, I notice that the xml files received with the ecw 
images only have projection info in them, and not the georeferencing info.
Is the georeferencing info embedded in the ecw files (like geotiff)? I 
tried looking in the ecw file with a binary editor, but saw nothing obvious.
