2. Requirements

  Oracle OCI shared libraries.

3. Setting up GDAL

  3.1 Unpack the package

  unzip gdalNN_linux64.zip

  If the plugin drivers are shipped as zip files under gdal/lib/gdalplugins, 
  unzip plugin drivers into the same directory

  3.2 Choose whether to use GDAl with or without HDFS support:

    3.2.1 Use GDAL without HDFS support

    edit setup_gdal.conf for the plugin SDK libraries.

    The script 'setup_gdal.conf' will prepare the environment variables
    for the use of GDAL tools on the current user's command line session.

    Execute the command:

      source setup_gdal.conf

    3.2.2 Use GDAL with HDFS support

    edit setup_hdfs_gdal.conf for the plugin SDK libraries.

    If the environment variables LD_LIBRARY_PATH and CLASSPATH are not set up 
    for HADOOP, uncomment the section "Setup the environment for HDFS" and set
    the path to HADOOP and JAVA JRE.

    Execute the command:

      source setup_hdfs_gdal.conf

  3.3 Test if GDAL is working properly:

    gdalinfo --version
    gdalinfo --formats
    gdalinfo --format georaster

  In case of errors verify if all requirements are met. See examples
  on 'setup_gdal.conf' or 'setup_hdfs_gdal.conf'.

4. Installing GDAL on a different machine

  Copy the ZIP package according to the target machine operating system.

  On the target machine, expand the ZIP package and follow the 
  instruction on README.TXT.

  For other operating system, follow the instruction on how to 
  download and compile the GDAL source code at GDAL website.
