Moritz, If once you've set LD_LIBRARY_PATH, ldd doesn't report any unfound library, then you could check if GDAL_DRIVER_PATH is defined and make point it to /usr/lib/gdalplugin (although that path should be hardcoded in the GDAL library by default) You can also do "strace gdalinfo 2>&1" and look if gdal_MrSID.so is loaded. > I don't know if I completely misunderstand how this should be done, or > if this a bug of some sorts. > > Several questions are open for me: > > - Seeing that the SDK seems to have been compiled with gcc44 do I have > to use that too ?

Hum, that might cause problem, or not, but I assume they would appear later with crashes or nasty behaviour when actually reading a raster. But that shouldn't prevent the plugin from being used.
