SIMPLE INSTALLATION AND USAGE EXAMPLE
-------------------------------------

$ tar -xzvf lib3d-mec_ginac-v1.1_and_example.tar.gz
$ cd lib_3d_mec_ginac-1.1.0
$ ./configure --prefix=`pwd`/..
//if problems with libtool use ./autogen.sh --prefix=`pwd`/.. instead (youll have to instal libtool and probably autotools)
$ make
$ make install
$ . ./local_environment.bash
//The previous file contains
#!/bin/bash
export LD_LIBRARY_PATH=`pwd`/../lib
export PKG_CONFIG_PATH=`pwd`/../lib/pkgconfig
$ cd examples/galera/
$ g++ -o main_eccomas2007  main_eccomas2007.cc -I../../../include  -L../../../lib -l_3d_mec_ginac-1.1 -lginac -lcln -lgmp
//or in a more elegant way
$ g++ -o main_eccomas2007  main_eccomas2007.cc `pkg-config --cflags --libs lib_3d_mec_ginac-1.1 ginac cln gsl`

$ cp ../common_code/qr_nm.c .
$ cp ../common_code/qr_nm.h .
$ cp ../common_code/newton_raphson_qr.c .
$ cp ../common_code/newton_raphson_qr.h .
$ cp ../common_code/printing.c .
$ cp ../common_code/printing.h .

$ ./main_eccomas2007 DOWN YES
Alternatively
$ ./main_eccomas2007 UP YES
$ touch atom_def.c
$ touch atom_def.h
$ ./main_eccomas2007 DOWN NO
$ ./main_eccomas2007 UP NO

$ evince *.eps &

$ ./clean.bash

You will need GiNaC (http://www.ginac.de) and GSL(GNU Scientific Library http://www.gnu.org/software/gsl/), to compile the library (maybe libtool).

The example needs and gnuplot (http://www.gnuplot.info/).

(The versions I'm using are
My actual Ubuntu 8.10
libginac1.4-1.4.3-1 libginac1.4-dev-1.4.3-1
libgsl0ldbl-1.11-2, libgsl0-dev-1.11-2
gnuplot-4.2.3-1

My old fedora
$ rpm -q gsl
 gsl-1.8-1.1
$ rpm -q ginac
 ginac-1.3.6-1.fc6
$ rpm -q cln
 cln-1.1.13-2.fc6
$ rpm -q gnuplot
 gnuplot-4.0.0-12
)

The program is the one presented in Eccomas2007 (1), with some additions that allows it to export C code and to perform a simplistic dynamic simulation.
