pss - Polynomial System Solver
Version 5.1 pre-release 1

This is a PRE-RELEASE. It computes mixed volumes, all other
actions depend on luck.
EASY INSTALLING.
You may download the latest version at
http://sourceforge.net/projects/pss5/
You will need a linux system with some version of MPI installed
(compilers and run-time environment), Lapack and Blas. You also
need some usual programming tools like GNU automake, lex and yacc
to build the executable. All those are provided in most linux
distributions. Fweb and Latex are recommended.
Unpack the source code:
tar -xvf pss5-pre1.tar.gz
This will create a directory pss5. Move to that directory:
cd pss5
The easy way: just type
./autogen.sh
./configure
Look at the output for errors or unmet dependencies. If all worked
smoothly, there will be a Makefile in the current directory. Type
make
This should create the executable pss in the main directory. To install
pss system-wide, you need superuser privileges. If you are in sudoers list,
sudo make install
Anothe possibility is to get into superuser mode (su -), move back
to the directory where you built pss, and type
make install
If you want just to install pss in your account, the procedure is
./configure --prefix=<your home directory>
make
make install
and no superuser privileges are needed.
CHECKING YOUR MAXIMA VERSION
You will need a recent version of maxima, and a lisp version tested with
Maxima that can deal with linux pipes. Those seem to be
lisp(CMUCL),scl(SCL),sbcl(SBCL),lisp(ACL),openmcl(OpenMCL)
Enter wxmaxima.
Type:
system("ls")
You should see files from your current directory.
Now type:
load("graphs");
It will take a while to compile the package. Then,
draw_graph( icosahedron_graph());
You should see an icosahedron.
If any of those steps failed, reinstall Maxima as explained
below. Otherwise, jump to INSTALLING THE MAXIMA INTERFACE.
INSTALLING THE MAXIMA INTERFACE
1) Enter in superuser mode, enter aptitude or synaptic and remove
packages maxima, wxmaxima and related.
2) Still inside the package manager,
install the libalien-wxwidgets-perl package
Install a lisp package. I tested cmucl (available only for 32bits memory
model) from
http://www.cons.org/cmucl/download.html
Another possibility is sbcl (available on debian). Unfortunately it
cannot load the lapack routines to Maxima.
su
cd /usr/local
tar -xvf ~gregorio/Downloads/cmucl-20f-x86-linux.tar.bz2
exit
3) Download maxima from http://maxima.sourceforge.net
4) Download wxmaxima source from http://wxmaxima.sourceforge.net
5) Unpack:
tar -xvf Downloads/maxima-5.35.1.tar.gz
tar -xvf Downloads/wxmaxima-14.12.1.tar.gz
6) Install maxima:
cd maxima-5.35.1/
./configure
(Check the output to verify dependencies are OK)
make
su
make install
exit
7) Install wxmaxima
cd wxmaxima-14.12.1/
./configure
(Check the output to verify dependencies are OK)
make
su
make install
exit
RUNNING PSS
ADVANCED INSTALLING. You may also want to choose between different
compilers or implementations of a library. Some computer facilities
use the "Modules" package to let you choose. For instance, you may
have the choice between gcc/g++ with open MPI and LAPACK or
Intel compiler with mvapich and Intel MKL. For each choice, you
should load the appropriate modules, for instance:
module load mvapich2
In case you want to link with MKL, you may want to uncomment a couple of
lines in configure.ac, and then follow the instructions.
Then you ./configure, make and make install.
MORE ADVANCED INSTALLING. If you need to modify the makefiles,
change the Makefile.am instead of Makefile.in and Makefile.
Before running ./configure, run
./autogen.sh
RUNNING WITH MAXIMA.
Enter wxmaxima (assuming it is installed). Type:
file_search_maxima:append (["/home/gregorio/pss5/src/maxima/$$$.mac"],file_search_maxima);
where you replace the path with the path to your pss5 directory.
Then, load presentation.wxm and press control-enter together to go
from line to line.
THE GUI (under development!)
Install python-wxtools
Install python3-opengl
python-wxgtk3.0-dev
wx-config --libs --gl-libs
TROUBLESHOOTING
Some linux distributions do not have Fweb. You may download
the source, see http://w3.pppl.gov/~krommes/fweb.html
If it fails to compile, there are two things you should check.
In the file ratfor.c, comment out the deprecated definition
#ifdef NEVER
char * strpbrk;
#endif
In the "configure" script, replace
termcap0."$O"
by
termcap0.o
