Hi,
spent another day with Makefile and Gnuplot, shell scripting, larning gnuplot to read a script, to read output from shell script , to read data file and more.

One example I follow now
compiling basic .c code examples from the net is:

gcc helloworld.c -o helloworld

It doesn't work for another example .c code program from the net

[admin@oo helloworld]$ gcc squares.c -o squares
squares.c: In function 'main':
squares.c:8: error: expected expression before '=' token
[admin@oo helloworld]$

---------
squares.c code is
what is wrong ?
--------------
#include <stdio.h>
main() {
double x;
FILE *datafile;

datafile = fopen("squares.dat","w");

for(x = 0.0; x < = 4.0; x += 1.0)
fprintf(datafile, "%4.1f %4.1f\n", x, x * x);

fclose(datafile);
}


This program should create data file to be read by gnuplot.

Here is a C program to create this file.

pptemplate

PPTEMPLATE(1)						User Contributed Perl Documentation					     PPTEMPLATE(1)

NAME

       pptemplate - script to generate Makefile.PL and PP file skeleton

SYNOPSIS

	       # generate Makefile.PL and mymodule.pd in CWD
	       pptemplate PDL::MyModule;

DESCRIPTION

       The pptemplate script is the easiest way to start a new module for PDL that contains PP code (see also PDL::PP). The usage is simply

	 pptemplate modulename;

       As a result pptemplate will generate a perl Makefile for the new module (Makefile.PL) that contains the minimal structure to generate a
       module from PP code and also a skeleton file for your new module.

       The file will be called mymod.pd if you called "pptemplate" as

	 pptemplate PDL::CleverAlgs::Mymod;

       I suppose you can work out the naming rule ";)". If not resort to experimentation or the source code.

       "pptemplate" will refuse to overwrite existing files of the same name to avoid accidents. Move them out of the way if you really want to
       scrap them.

   Options
       Currently there is only the "-i" option which switches "pptemplate" into the so called internal mode.  It should only be used when you are
       starting a new module within the main PDL tree that is supposed to be part of the PDL distribution and the normal PDL build process, e.g.

	  cd PDL/IO;
	  mkdir Mpthree; cd Mpthree;
	  pptemplate -i PDL::IO::Mpthree;

BUGS

       Maybe ";)".  Feedback and bug reports are welcome.
