[Gdal-dev] JP2MrSID driver. How to get it?

[Daniele Romagnoli]

Hi,
I'm working on LINUX (Ubuntu) to fix some things on ImageIo-ext project.
I have read some olds threads talking about conflicts between Kakadu and
MrSID's Jpeg2000 support.
I'm using GDAL 1.4.2 with MrSid (GeoExpress Decode SDK 6.0.7.1407) and
Kakadu 5.2.6.

When building GDAL after configuring it for MrSid and Kakadu, I get only
JP2KAK and MrSID (using GDALInfo --formats).
I then attempted to edit GDALMake.opt after ./configure, adding MRSID_FLAGS
=   -DMRSID_J2K and I get errors when building.
However I have noticed that when configuring with support for only MrSID,
JP2MrSID appears in the list of supported formats (So, manually setting
MRSID_FLAGS is not required :P)

It is possible to support both JP2KAK and JP2MRSID driver on Linux?
Thanks a lot.

Best Regards,
Daniele
