Daniele,

I see MRSID_J2K is deliberately excluded by configure if Kakadu is being
built in.  I don't recall all the details, but the MrSID libraries include
a variant of Kakadu as I understand resulting in (apparently) various kinds
of symbol conflict problems.

When MRSID_J2K is defined, -lltikdu is also added to the link libraries.  If
you added this you could likely at least experiement with having both enabled
at the same time.

Best regards,
