fortran on archlinux

fortran? what is this?:

fortune -m FORTRAN wrote:

FORTRAN is a good example of a language which is easier to parse
using ad hoc techniques.
                -- D. Gries

FORTRAN is for pipe stress freaks and crystallography weenies.

FORTRAN is not a flower but a weed -- it is hardy, occasionally blooms,
and grows in every computer.
                -- A.J. Perlis           [What's good about it?  Ed.]

FORTRAN is the language of Powerful Computers.
                -- Steven Feiner

It's multiple choice time...

        What is FORTRAN?

        a: Between thre and fiv tran.
        b: What two computers engage in before they interface.
        c: Ridiculous.

You can measure a programmer's perspective by noting his attitude on
the continuing viability of FORTRAN.
                -- Alan Perlis

FORTRAN?  The syntactically incorrect statement "DO 10 I = 1.10" will parse and
generate code creating a variable, DO10I, as follows: "DO10I = 1.10"  If that
doesn't terrify you, it should.

ok, and now serious:

we need a fortran compiler in archlinux ... at least to be able to compile some scientific apps ... that are often used by students (the people that invented linux wink )

ok: to be a little bit precise:

what is not in archlinux, and should be is:

f2c (a fortran to C translator)
http://www.netlib.org/f2c/

g77 (GNU F77 compiler ...  part of gcc ... no idea how or where to download)
http://gcc.gnu.org/onlinedocs/g77/News.html is the only link i found with gg

and maybe the intel fortran compiler:
http://developer.intel.com/software/pro … noncom.htm
it's free for noncomertial use

and for the future, what about the f compiler?
ftp://ftp.swcp.com/pub/walt/F

i dont have time right now to get into how to install any of them on a linux, to built a package, but it would be great having at least f2c and g77

Re: fortran on archlinux

A quick "fix" to get g77 ?!? - try to modify the gcc-PKGBUILD by adjusting the

--enable-languages=c,c++,objc

part - but I forgot how to enable g77 :-) ...

Otherwise, I may be doing a package/PKGBUILD for one or the other - but am quite busy lately (and I need a break, so I browse the forum ;-) ...). i have installed the Intel compiler on several machines several times.

However, this raises an important question about PKGBUILDS and packages. It is possible to make a PKGBUILD for the Intel compiler, but I doubt the license permits distributuing the binary. I know, it's free for non-commercial use, and the user still has to get a license key from Intel, but Intel may still not like redistribution of their package. (who reads these licenses :-) ? ...)

There is different software similar to this where AL and the package builders can only distribute PKGBUILDS and no complete packages. This is not really a problem yet - the AL developers just have to make sure that such software does not get on any CD or ftp archive.

Re: fortran on archlinux

i believe that the g77 source is available from the same ftp url as the gcc. i believe they do have the code for g77 separate.

Re: fortran on archlinux

I just dug through the gcc site and found the following :

http://gcc.gnu.org/install/download.html

and if one compares to

ftp://ftp.gnu.org/pub/gnu/gcc/gcc-3.3.1/

one does see the big all-in-one package and the individual parts.

It appears that AL requires the full package, so enabling fortran with

--enable-languages=c,c++,objc,f77

(which I found on http://gcc.gnu.org/install/configure.html )

should just get you g77  !

And finally, the latest and greatest details are on
http://gcc.gnu.org/install/

all right, back to work :-) ... and eventually, I will actually DO something about Fortran packages instead of just posting info :-) But while I am at it, I throw more URL's at you ...

http://g95.sourceforge.net/
http://gcc.gnu.org/frontends.html

What's wrong with this perfectly legal declaration of a variable ... :twisted:

Oh, and search this site for the string "Fortran" ...

http://www.rickadams.org/adventure/a_history.html

and then grab this famous piece of software from

Re: fortran on archlinux

andy,

thanx a lot for the links ... i didnt know that "Adventure" was written in fortran originally ... funny ... as soon as i find time i will try to recompile gcc with f77 ... now (its 23:15) it's a little bit too late to play around with gcc (the testing can be complicated) ...

*****************************************
... and when it works fine, maybe we can have gcc with f77 enabled as standard in archlinux?
-> what do you think about this idea?
*****************************************

the g95 is interesting, but actually i think it is too early in developement to be used as default fortran compiler

the other gcc-frontends are also interesting

(thanx for the links, again)

"DO 10 I = 1.10" was an example in a fortune!!! it's not me that said that it is incorrect! --- it's logical if you are allready used with fortran, but compared to more primitive languages it is not perfectly correct

Re: fortran on archlinux

oh yes, g95 is WAYYY too experimental. I look at this page every few month - but at least this project is still active !

And I did realize that that DO-example came from the fortune and not from you :-) ... and I won't write any more about using (or not using) spaces in Fortran-source ... :-) ....

First, an update on the Intel Compiler PKGBUILDs : http://bbs.archlinux.org/viewtopic.php?t=2217
