Hi I'm Linux new user, I install slackware 13.37, recently I install gcc-gfortran-4.5.2-i486-2.txz but i have no idea how to run the program, I know is not like windows because I don't see any icon to run the program.
Can help me whit this problem please how to run from konsole or any other form.

I think your biting off way more than you can handle here.

Short answer

gfortran

Long answer requires more space than this forum allows (just to give you an idea of what your in for)

have a look at
you can find the most comprehensive documentation on its site.

FORTRAN

That brings back memories.

See ponce's link, and also the main wiki: http://gcc.gnu.org/wiki/GFortran and perhaps here: http://en.wikibooks.org/wiki/Fortran/Fortran_examples

I was torn for examples (FORTRAN 77 and WATFIV were the last dialects I used), so, rather, here is a more modern example using Fortran 90:

Trivia quiz: FORTRAN is an acronym for what phrase?

A problem that can't be solved with FORTRAN isn't worth to be solved, at all:
Real Programmers Don't Use Pascal

Quiz: FORTRAN stands for FORmula TRANslation, which indicates that the language was created for natural scientists and Mathematicians, while COBOL was "for business".

BTW, are recent incarnations of Fortran supported by GCC, including the "object-oriented stuff"? A quick web search didn't give me a clear answer... Does anyone happen to know?

Regarding the original post: To my knowledge some integrated development environments (IDE) support running the Fortran compiler from GUI. I am not sure that I remember it correctly, but I think it was possible from Netbeans, and may now be possible from Eclipse (yes, originally both were developed as Java IDEs, but support other languages, as well), but I haven't used any of them for many years, so you'll have to check this out yourself.

I haven't done it, but you should be able to set up the KDE development environment to do fortran (well maybe not 4.x...). Any decent IDE should be able to handle gcc-fortran. http://en.wikipedia.org/wiki/Compari...t_environments

Don't know about "object-oriented stuff" - such newfangled nonsense is for you youngsters. My quick web search resulted in:

IIRC, object-oriented programming is a technique not a language. You can roll your own via C or just use C++ to make you life easier. Making the compiler aware of these tricks aids in efficiency and speed.

Yeah.


Well, at least encapsulation should be supported by the language. This is a minimum requirement for oo programming, I think. If you can hide local variables, you can mimic other oo stuff, such as inheritance, if you need it and know how to deal with it. E. g., it takes no less than three years of professional experience, before a newbie is able to know how to use multiple inheritance and operator overloading in C++. And it would take me five years, probably. That explains the popularity of languages like Java, I guess...

Why this excurse? Because FORTRAN 77 did not support any concept of oo programming. Newer version claim, they did, but I don't know, if anyone really uses/needs it.

Fortran ... you will need more space than is able to post here in a reasonable time


the changes over the years dose make running old and just older lab code "fun"

one friend is an old hand with 77 and posts NEW software in 77
one other uses 90 ( at cern) , the 77 drives him batty .
me i end up in the middle of the two going at it back and forth


gcc changed names " gfortran"

on Mingw and CygWin it is still g77 and g90
some OLD red hat 4 systems might still be using g90 but most modern OS's are using " gfortran"



Google it and do some research

Ah fond memories. I go back a bit further to WATFOR and Ten Statement FORTRAN

LOL, ya old geezer. I couldn't get rid of those punch cards fast enough....
