Supplemental Libraries for GrADS version 2.2

There are many supplemental libraries that are required to enable various features in the GrADS executable. Building all these libraries from source is not necessarily easy; this page provides some guidance and suggestions that have led to success on COLA's unix systems (64-bit linux running CentOS, and Mac OSX). COLA's objective in building GrADS is to make our binary releases portable, so we strive to build all the libraries from scratch, disabling features GrADS doesn't need, and then link statically when building GrADS. If you are building GrADS from source but not planning to distribute your build, then you may find that many of these libraries are already installed on your system and you can link with them dynamically. In this case, use the --enable-dyn-supplibs option with the GrADS configure script. Please post questions about building from source to the GrADS Users Forum. If you have the proper privileges, you may install these anywhere on your system instead of $HOME, just be sure to change the commands listed in the table below to accomodate your own installation.

To begin, make a directory top level directory for the supplibs under your $HOME, or some other suitable directory:
mkdir $HOME/grads/supplibs
setenv SUPPLIBS $HOME/grads/supplibs

Make a subdirectory where you will store the tar files containing the library source code:
mkdir -p $SUPPLIBS/tarfiles

Make a subdirectory where you will store the source code when unpacking the tar files:
mkdir -p $SUPPLIBS/src

Get the src from COLA's FTP server:
cd $SUPPLIBS/tarfiles
ftp cola.gmu.edu
<login as anonymous>
cd grads/Supplibs/2.2/src
mget *
quit

These are the directories where the compiled libaries, pkgconfig files, include files, and any executable utilities will be installed. This will be created automatically by the library software, there is no need to create them manually.
$HOME/supplibs/lib
$HOME/supplibs/include
$HOME/supplibs/bin

This seems to be necessary in order to link the libraries dynamically to create the shared object file (libgradspy.so) for the python interface:
setenv CFLAGS -fPIC

When you are done, unpack the GrADS source code tarball under $HOME. Change into the new GrADS directory you just created, and type ./configure. When the configuration is done, it will show a summary of which features have been enabled. Then type 'make install' and look for your executables in the ./bin directory.

Good Luck!!

g2clib 1.6.0

Decodes data in GRIB2 format.
Requires: zlib, png, jasper
home page

cd $SUPPLIBS/src
tar xvfz ../tarfiles/g2clib-1.6.0.tar.gz
cd g2clib-1.6.0

Note1: There is no configure script in this library, so you must edit the makefile manually. Change the "INC" variable as indicated below. Be sure to write out $SUPPLIBS explicitly:
   INC=-I$SUPPLUBS/include -I$UPPLIBS/include/libpng15
You must also edit the "CFLAGS" variable to include the "-fPIC" option. On some unix servers it may also be necessary to remove the "-m64" and/or "-D__64BIT__" options.

Note2: Version 1.6.0 of the grib2 C library introduced a new output file naming convention that includes a version number. When manually installing in it the $SUPLLIBS/lib directory, rename it to the old (static) filename. It is also necessary to manually install the grib2.h file in the $SUPPLIBS/include directory.

make
/bin/cp -f libg2c_v1.6.0.a $SUPPLIBS/lib/libgrib2c.a
/bin/cp -f grib2.h $SUPPLIBS/include
