Daniele -

I'm now working on a RHEL6 distribution and I am looking at the "Image I/O-EXT - Setup Guide 1.1.1". Has there been any update to that; more specifically, does the Java dist still have to be 1.5.0_17? I notice that the guide assumes that you are working on Linux Fedora Core 5, but I am not sure how that maps to RedHat Enterprise Linux release numbers.

Hi Garey,
we have sometime encountered a similar issue when testing the linux libraries on some particular distro due to the underlying base libs being not available/being differents on that distro. In those cases, after some quick attempts we have concluded to build GDAL on the specific machine to make sure to solve this kind of issue with the internal libraries. If you need to build the base GDAL 1.4.5 by yourself, you can follow some steps provided in the ImageIO-Ext Setup guide [1].

To be more specific, the chapters/paragraphs you should be interested in are:
3.2
3.6.1
3.7.2
3.7.3 (all subchapters)

For more specific info on external libraries (such as MrSID as an instance) you can take a look on the related paragraph.

Hope this helps.
Let me know if you have any issue.

Best Regards,
Daniele

    Hi -

        I am having the following problem installing the GDAL plugins in
    GeoServer 2.1.1 on RHEL5:

    Jul 22, 2011 10:43:50 AM
    it.geosolutions.imageio.gdalframework.GDALUtilities loadGDAL
    WARNING: Failed to load the GDAL native libs. This is not a problem
    unless you need to use the GDAL plugins: they won't be
    enabled.java.lang.UnsatisfiedLinkError:
    /opt/jdk1.6.0_23/jre/lib/i386/libgdaljni.so: /usr/lib/libstdc++.so.6:
    version `GLIBCXX_3.4.9' not found (required by
    /opt/jdk1.6.0_23/jre/lib/i386/libgdal.so.1)


    I found information about downloading a later version of libstdc++ and
    putting it into a separate directory on the net, so I tried that.
    I set LD_LIBRARY_PATH to include the new libstdc++. No luck.

    I edited catalina.sh and added the argument
    '-Djava.library.path="/path/to/new/libstdc++.so" to the invocation of
    tomcat. Still no luck.

    Anyone have any ideas?
