Building
========

Detailed building instructions are available at:

  http://ogdi.sourceforge.net/build.html

Unix
----

1) Set TOPDIR to point to the home directory of the OGDI source tree. 

   eg. 
   TOPDIR=/usr/ogdi-3.1.3
   export TOPDIR

2) Run configure.

   eg. 
   ./configure

3) Build with make (GNUmake is required). 

   make

   NOTE: on some platforms you will need to add the shared libraries to
   your LD_LIBRARY_PATH for the link phase to complete.  
 
   eg. 

   LD_LIBRARY_PATH=$TOPDIR/bin/Linux
   export LD_LIBRARY_PATH

4) Install.

   make install

Windows
-------

Windows works similarly, but a preset configuration is used instead of
building one with configure.

Requirements:
  o Cygwin (build shell) from http://www.cygwin.com/ with the GNU Make utility
  o Microsoft Visual C++ (make sure it works at the commandline from bash,
    run VCVARS32.BAT / VCVARSALL.BAT if not). Make sure that the link.exe command
    that comes with Cygwin does not override the link.exe of Visual Studio. You
    may need to alter the PATH to make sure Visual Studio binaries come first, or
    rename the link.exe in Cygwin

1) Set TOPDIR to point to the home directory of the OGDI source tree.
   (Do not use /cygdrive/c/ syntax)

   eg. 
   TOPDIR=c:/ogdi-3.1.3
   export TOPDIR

2) Set the target build configuration

   eg.
   TARGET=win32
   export TARGET

3) Build with make.

   make

Running
=======

Briefly, ensure that $TOPDIR/bin/$TARGET is in the path.  Ensure that
$TOPDIR/bin/$TARGET is in the LD_LIBRARY_PATH on Unix. 

To use in local mode try a command like:

 ogdi_info -u gltp:/vrf//home/even/data/vm2alv2_texash/texashd:/toronto/dted

To use via the server, run gltpd.exe first in the background.  On windows, run 
portmap.exe before running gltpd.exe.  Then use a command like:

 ogdi_info -u gltp://localhost/vrf//home/even/data/vm2alv2_texash/texashd:/toronto/dted
