Problems to add POVRAY and VRML terminal to GNUPLOT 4.0.

Hello guys!!!

Currently, I am using CYGWIN and from there I can run GNUPLOT.
One night I found out from internet a website (content in portugues) how to install POVRAY. According to this website, I followed these steps:

$ wget -c ftp://ftp.dante.de/pub/tex/graphics/...t-4.0.0.tar.gz

$ wget -c http://t-kita.net/gnuplot_povrml/gnu...vrml-0.3.patch

$ tar zxvf gnuplot-4.0.0.tar.gz

$ cp gnuplot_povrml-0.3.patch gnuplot-4.0.0

$ cd gnuplot-4.0.0

$ patch -p1 < gnuplot_povrml-0.3.patch

Due to the CYGWIN has already installed the GNUPLOT 4.2 on the system, I did this:

$ ./configure --prefix=/home/user/selected_folder/

$ make install

After that,

$ cd ~/selected_folder/bin/
$ ./gnuplot

So, I can run GNUPLOT 4.0, but when I want to create this kind of graphs

set terminal povray
set xlabel "x-data"
set ylabel "y-data"
set zlabel "height"
set samples 20
set isosamples 20
set out "povray-demo1.pov"
splot x*y with points, x*10 with points ps 1.5, x-60 with d, -2*x-120 with lines
set out
!povray +FC +A0.5 graficoA.pov

The following message appears:

sh: povray: command not found

What can I do??? What did I do wrong? What did I forget? someone can tell me.

Probably just add the location of the povray runtime binary to $PATH, or instead of the script using '!povray', use the fully qualified filespec of the povray runtime binary.

Dear Rod,

Due to I'm a new user of Gnuplot, I cannot understand your first suggestion, please can you write how can I do that?

Thank you in advance

First, figure out where the povray runtime binaries are installed. Note the name of the directory where you find it. For the sake of argument, if it was found in the directory /usr/local/povray, then at the shell prompt where you start gnuplot:

Code:

PATH=$PATH:/usr/local/povray

Then, run gnuplot.
Gnuplot is trying to launch povray, but doesn't know how to find it. Like the shell, it may use $PATH to find programs. Adding a directory to the list in $PATH will tell it to look there, and it will then find it.
