Free software versus closed software

Dlaczego GNU GPL to warto (pl): http://www.gnu.org/philosophy/free-sw.pl.html

general languages for creating executable programs

fortran

f77 - moderately high level

the g77 compiler is GPL

suggestions on options when compiling

ZWiki:FortranExample

a program that changes galactic coordinates into right ascention and declination

ANSI definition (long and detailed)

http://www.fortran.com/fortran/F77_std/rjcnf0001.html

checking, portability

ftnchk
include statements fairly portable even though not strictly f77: http://www.math.utah.edu/~beebe/software/dcl2inc/dcl2inc.html

f90

higher level than f77, not yet any stable GPL or other free compiler

f95 - high level, but...

g95 is a GPL project to have a free-software fortran-95 compiler (which can also compile f90, f77)

[Perl] combines all the worst aspects of C and Lisp: a billion different sublanguages in one monolithic executable. It combines the power of C with the readability of PostScript. -- Jamie Zawinski

LAPACK/BLAS

http://www.cs.colorado.edu/~lapack/
- V3.0 contains 2793 .f fortran files, including test and installation files written?
- 1434 of these fortran files are in directories /SRC/, i.e. source files of LAPACK or BLAS
- why rewrite these since they're already written?

GNU Scientific Library - GSL

http://www.gnu.org/software/gsl/
np. http://www.gnu.org/software/gsl/manual/gsl-ref_2.html#SEC10
- na adjani
  - (1) gcc -c mojprogram.c
  - (2) gcc mojprogram.o -lgsl -lgslcblas -lm
  - ./a.out
- na galileo etc - moze warto uzywac makefile...
  - (1) gcc -L/scratch/7/boud/lib -I/scratch/7/boud/include mojprogram.c -lgsl -lgslcblas -lm -L/opt/lib/gcc-lib/sparc-sun-solaris2.6/2.7.2.3/ -lgcc
  - (2) setenv LD_LIBRARY_PATH {$LD_LIBRARY_PATH}:/scratch/7/boud/lib
  - ./a.out
- jak przygotować funkcji
- info gsl wtedy C-s Providing the function

plotutils - GPL plotting library

manual - http://gnu.signal42.com/software/plotutils/manual/html_chapter/plotutils_toc.html
przykład program - http://gnu.signal42.com/software/plotutils/manual/html_chapter/plotutils_9.html#SEC46
- kompilacja
  - (np na zwykly linuksa) gcc -lplot -L/usr/X11R6/lib testplot.c -lXaw -lXmu -lXt -lXext -lX11 -lm
  - na galileo itd:
    - (1) gcc -L/scratch/7/boud/lib -I/scratch/7/boud/include plot_example.c -lplot -L/usr/X11R6/lib -lXaw -lXmu -lXt -lXext -lX11 -lm
    - (2) setenv LD_LIBRARY_PATH {$LD_LIBRARY_PATH}:/scratch/7/boud/lib
    - (3) ./a.out lub ./a.out > cos.ps itd
Uwaga: gnuplot nie jest GPL, jest oprogramowanie non-free . (Też nie jest projekt GNU - FSF.)
plotutils jest GPL - daje biblioteki libplot dla C i libplotter dla C++ i commandy jak graph, plot.

Numerical Recipes - http://www.nr.com/ - good for learning, but you may not redistribute the code as part of your program packages - better learn to use GSL, BLAS, LAPACK, etc.. Bardzo znane między astronomami, ale lepiej używać wolne oprogramowanie, jak GSL i LAPACK żeby twoj programy nie są ,,w wiezieniu".
