Hey all, Short question first, then the longer explanation.
*QUESTION*: My java SWIG bindings, generated from source, can't read the HDF4 format. How can I fix this? *CONTEXT*: I've spent the last couple of days trying to generate java bindings for gdal that will allow me, essentially, to run this piece of java code -- https://svn.osgeo.org/fdo/tags/3.4_G032/Thirdparty/gdal/swig/java/apps/gdalinfo.java gdal.AllRegister() works great, but I can't get past gdal.Open(), as the bindings don't recognize HDF4. My final goal is to create a maven package that has gdal.java and the native dependencies bundled up together. This way, I can run jobs on NASA's MODIS tiles on Elastic MapReduce, simply by making sure the MapReduce nodes have gdal and hdf4 installed locally (using apt-get gdal-lib). I built from source, using ./configure --with-hdf4=/opt/local/ --with-hdf5=/opt/local/ (macports versions). I CDed into swig, ran make, then CDed into java, and ran make again. This gave me gdal.java, plus all of the native dependencies as dylibs, which I moved to a directory on java.library.path. I wrote this piece of code to test my setup: https://gist.github.com/784850 Now, that code, as it runs now, returns this- "(my file path) It doesn't recognize the HDF file, even though I specified --with-hdf4. *So, my question is,* *what special things do I need to do to get make java swig-bindings to recognize these damn formats?* Do I have to specify something about swig when I run ./configure initially? (BTW, I'm running on Mac OS X, and also had to tweak the java path settings inside java.opt. ALL I need to be able to do, really, is open up the hdf file and extract the subdatasets. I plan on writing an article describing how to run GDAL on Amazon's Elastic MapReduce, after I'm done with all of this stuff.
