This directory contains LaGriT source fortran and C files. 
The include file lagrit.h sets OS and date tags for the banner.
The lagrit*.h files are OS versions that are copied to lagrit.h

To build, use Makefile, Makefile.depends 
type 'make help' to see a listing of make options
The make utility will maintain object files
as defined in OBJDIR. There is a seperate directory for each set
of optimized and debug for each OS platform. make will then check the
object files in the appropriate directory for updates. 
The Makefile format requires GNU Make version 3.79.1 or later

To check variables in Makefile:
    make list

In general to update libs and executable on each platform
    make install (update optimized lib and put into LIBDIR) 
    make COPT=-g install (update debug lib and put into LIBDIR)
    buildbin or buildbin opt (build executable into current dir) 

Build scripts for compiler flags and names include:
buildbin.scr - SunOS, Linux, and Darwin (mac)
go.scr - single set of commands to compile for Ubuntu linux
config.sh - using linux modules and enviroment variables

==============================================================
V3.2 includes recent updates for WINDOWS with cygwin
See general instructions in /docs/build* and cmake*
and local README and scripts in this directory.

LIBRARIES: lg_util (included) and ExodusII (external)

Compile lg_util library in directory lg_util/src

Example: linux debug and optimized version 64 bit
  check mm2000.h that BYTES_PER_INT = 8
  if not then Remove and re-make mm2000.h from mm2000_header.F
      rm -f mm2000.h
      gcc -g -E -m64 -Dlinx64 mm2000_header.F -o mm2000.h
      cp -p mm2000.h objects_lin64_g_gfort4.5/
      cp -p mm2000.h objects_lin64_o_gfort4.5/

  make COPT=-g lib
  make lib

ExodusII 6.09
  1) zlib/1.2.5/gcc-4.8.2              
  2) hdf5/1.8.6/gcc-4.8.2-serial       
  3) netcdf/4.3.3.1/gcc-4.8.2-serial
  4) exodusii/6.09/gcc-4.8.2-serial

/n/swdev/packages/Ubuntu-14.04-x86_64/exodusii/6.09/gcc-4.8.2-serial/lib
  libexodus.so  libexoIIv2for.so 
  (static libs should be libexodus.a  libexoIIv2for.a) 
  copy include files to src (or add -I to the link command)
    exodusII.h (for C calls)  
    exodusII.inc (for Fortran calls) 
    exodusII_int.h  exodusII_int.inc

NOTE: exodusII.inc is incomplete (Greg will fix in his version)
Add these lines if it does not exist:
       integer EX_ELEM_SET
       parameter (EX_ELEM_SET  = 10)

==============================================================
If do not have and do not need the ExodusII and netCDF libraries.

LaGriT V3.0 supports ExodusII file format output (which sits on top of netCDF). 
This means that if you want to compile your own code you have to build the ExodusII and netCDF libraries yourself. We do not distribute those packages. A quick and dirty option to compile without these libraries would to just take the code that calls those libraries and replace dumpexodusII.f it with:

     subroutine dumpexodusII(ifile)
     return
     end

or copy dumpexodusII.f.withnoexo to dumpexodusII.f
