Re: [Geoserver-users] ImageioExt and 1.7 beta2?

Hi,
Several months ago, during our work of getting GDAL working under Linux from
Java, we have noticed that, after building GDAL without setting those
C??_FLAGS when generating JAVA Bindings, JVM crashes with sigsegv errors. I
will checkout GDAL 1.5.x and I will look for them.

Anyway I need some more info in order to better know your procedure.
Which jar containing the generated java bindings are you using? (This jar
contains the native calls to the libgdaljni.so)

You said that you copied all the "new" jars from the WEB-INF/lib folder.
Therefore I guess you have also copied the
imageio-ext-gdal-1.0-SNAPSHOT.jar.
This file is the gdal.jar produced by SWIG when generating java bindings (It
has been renamed like this to know the proper imageio-ext / GDAL version).
Since imageio-ext is  actually built against gdal 1.4.4, the imageio-ext
libs contained in that geoserver release leverage on a GDAL 1.4.4 version,
unless you have replaced our imageio-ext-gdal-1.0-SNAPSHOT.jar with your
SWIG's generated gdal.jar relying on a GDAL 1.5.x version.
However, I have noticed in the past (more info on the imageio-ext dev ML
archive) that the SWIG Bindings produced by version 1.5.X are slightly
different with respect to the ones coming from 1.4.4. Therefore, in that
circumstance I have created an unofficial small patch for an user which
needed to work with GDAL 1.5 and MrSID 7 to use it with our ImageIO-ext
project.

Let me know.

Best Regards,
Daniele
