Re: [Geotools-gt2-users] JP2MrSIDReader Unsatisified Linked Error

[Jeff S. <jef...@ne...>]

Simone,

Thanks for your help. The problem that some of the dlls reference other dlls, and they do not look in the -Djava.library.path. The users that user our software may not have permissions to edit the classpath (or may not know how to). I used DependencyWalker to figure out which libs depend on which other ones. Explicitly calling System.loadLibrary on each of those libraries fixed the problem.

Thanks,
Jeff

Ciao Jeff,
I guess you took the native libs from here:

https://imageio-ext.dev.java.net/files/documents/7505/144606/imageio-ext-1.0.5-windows32-dlls.zip

If so, I would try to unzip in a directory and run a gdalinfo --
formats to get the list of supported formats and confirm that JP2MrSid
is supported.

That said, I would also add the directory where you unzip your files
to the windows PATH variable.

Let me know if that helps.

Ciao,
Simone.
