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

ZWiki:FortranCompilerHints

• 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)
  • http://cvs.sourceforge.net/viewcvs.py/*checkout*/g95/g95/COPYING?content-type=text%2Fplain&rev=1.2
• http://g95.sourceforge.net/

python - high level scripting language

• http://www.python.org

octave - high level scripting language

• OctavePl - some partial translations of the octave manual into po polsku, around 2003
• http://pagesperso-orange.fr/prthomas/intro.html

java - high level scripting language

(Uwaga - czy tylko stare wersji są prawdziwie wolne?? - java2.0)

• http://www.blackdown.org/java-linux/docs.html

• http://java.sun.com/docs/books/tutorial/

• http://www.mindview.net "thinking in java" (highly recommended book)

• http://www.eclipse.org IDE (integrated development environment) for java

• http://math.nist.gov/javanumerics/ numerical computing in java

• search on jni (java native interface) for using non-java libraries

• JavaVirtualMachines - a short guide through available JVMs and Java compilers

C - low level

(pl)

• C (język programowania)
• http://galaxy.uci.agh.edu.pl/~chwastek/lectures/C/spis.html

(en)

• http://en.wikipedia.org/wiki/C_programming_language
• FAQ - Frequently Asked Questions - http://www.eskimo.com/~scs/C-faq/top.html
• http://en.wikibooks.org/wiki/C_Programming
• man name_of_a_C_function gives you info (only useful once you've got past the basics) lub info name_of_a_C_function
• (zamykany? http://www.harpercollege.edu/bus-ss/cis/166/mmckenzi/contents.htm http://www.scit.wlv.ac.uk/~jphb/cbook/html/ slow, many small easy bits często robione błędy w C: http://www.comsc.ucok.edu/~pcarter/faq/common-c-errors.html)
• why C has a maximum size of arrays and what you can do about it

wykłady C

CwPiwnicach - wykłady/czwiczeń C zimo 2004r.

C++ - higher level than C - object-oriented

• http://www.desy.de/gna/html/cc/Tutorial/tutorial.html

perl - mix of low level and high level

• http://web.pertus.com.pl/tech/perldoc/perl5.html
• in English

• http://www.republika.pl/wieluk/strony/operlu.html
• po polsku

• [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

lisp

pascal

• info gpc
• Pascal (język programowania)

libraries for numerical computation

free (GPL sense) packages

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.

non-free packages

• 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".
