problem installing fortran77 on suse11

minaesm · 11-13-2008, 03:25 PM

hi every one
lately i'v installed suse11 on my laptop(dell-inspiron-1525) . for my project i have to compile a program (software doanloaded from internet). but the error is that i do not have f77. i dawnloaded a g77pack from net but i do not knowhow to install it on my suse11.plz help me and give instructions. thnks

So you DOWNLOADED something from the internet, but what? Did you download the RPM file, or did you download the source code? Where did you download it from? Did you look in the package or on that site, for the instructions???

If you downloaded the RPM file, (as root), type in "rpm -i <whatever file name you have>". Source code? Uncompress it, and go into the directory it created. There are probably installation instructions in there, along with auto-configure scripts.

I think that you do not need g77. You have gfortran installed in your system. Just type

Code:

which gfortran

to be sure. It should return something like /usr/bin. If not add the GNU compiler (4.3 or above) from your repositories.

Next, when you compile, probably the first step is to type ./configure. Type

Code:

./configure --help

to get a list of options. If you find something like F77 or FC, you can set either or both in this manner:

Code:

./configure F77=gfortran FC=gfortran

and you should be on your way.

The other option is (though i am not sure if it is the right thing to do) that you create a symbolic link 'g77' to gfortran.

Good luck!

hi and thanks for your help. i've downloaded " g77-3.2.3.tgz " from internet.does it the compatible file for linux???and how can i install it?

Did you read my first response to you? The part where it says "Uncompress it, and go into the directory it created. There are probably installation instructions, along with auto-configure scripts"???? Why don't you try that?

hi actually i did it and again when i try to compile my program again there was a fortran error

How about actually TELLING US WHAT THE ERROR WAS, if you'd like help.

hi . actually as i said before i did exactly what u and others said but again the same problem occurs. let me explain exactly what i want to do: i downloaded this software http://ab-initio.mit.edu/wiki/index.php/MIT_Photonic_Bands and i uncompress it in this path as root: usr/local/mpb . i opened terminal window and the error was this :

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.57. Invocation command line was

i typed " which gfortran " and the answer was /usr/bin/gfortran
then "./configure --help " and it was F77. so i did this :
./configure F77=gfortran
as u said but again the same problem while installing mpb package appeared.
then i downloaded a " g77-3.2.3.tgz" from this site : http://dir.filewatcher.com/d/OpenBSD...z.5386570.html
i put it and uncompress it in the path :
/usr/local/g77/
although i looked at installation instruction but i didn't any thing to help me install it .
thank u all

colucix · 11-17-2008, 04:04 AM

Looking at your config.log (see the relevant part below) it looks like you've not really set the environment variable F77:

Code:

...
$ ./configure 
...
...
ac_cv_env_F77_set=
ac_cv_env_F77_value=
...
...
F77=''
...

So please, do the following

Code:

export F77=gfortran
./configure

You don't need to install another fortran compiler if you already have one available on your system (and if it works for your needs). Also, when you look for some piece of software, it's better to try the yast package manager first to see if a pre-built RPM package is available for your system. Looking at the link you've posted, you've downloaded a g77 package containing binaries for OpenBSD and PowerPC architecture!!

hi and thank U for your help . i opened terminal windows in the directory of the software which i mentioned and i did what u said but an error occured :

colucix · 11-18-2008, 04:30 AM

You did it right, almost! The export command must be issued prior to launch ./configure, that is you create the compilation environment to which the configure script refers, then launch it. So the first thing is simply

Code:

export F77=gfortran

then in the same terminal (otherwise the F77 variable is lost) you will launch ./configure along with the required options (if any). You can find out the useful environment variables by running

Code:

# ./configure --help
<omitted>
Some influential environment variables:
  F77         Fortran 77 compiler command
  FFLAGS      Fortran 77 compiler flags
  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
              nonstandard directory <lib dir>
  CC          C compiler command
  CFLAGS      C compiler flags
  CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
              you have headers in a nonstandard directory <include dir>
  CPP         C preprocessor

Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.

As you can see the configure script looks for these environment variables, by which you can customize your compilation. For example you may chose your preferred fortran compiler, be it gfortran, ifort (the intel compiler) or pgf95 (the portland compiler) and so on.

That said, now you have to match the requirements for your compilation. You have to look at the developer's site for useful information and read the README and/or INSTALL files inside the source directory. Regarding the FFTW libraries, they are the "Fastest Fourier Transform in the West", a collection of routines to compute the discrete Fourier transform. They are not installed by default on OpenSuSE 11, so you have to open the Yast - Software management and install the fftw and fftw-devel packages. The -devel packages are those that provide the libraries and the header files, necessary to compile a software from source.

After installing ffwt relaunch the configure script and see the next requirement. Indeed, you're trying to install a software which has a lot of dependencies. Check them all with a bit of patience and the trick is done!

hi again everybody and thank you for your really useful helps to me and to my work , they really worked.
now i'm working on another program that is some codes written in f77 and the only thing that is written in its manual as " how to install" is putting it in the right directory (usr/local/the name of the program) and to open the terminal window and type this :
f77 -C -o gme.e gme.f ft2d.f sub.f

when i did it again this problem arised:

f77:command not found

i used what was suggested here for another problem with fortran but they did'nt worked .
what can i do now ? i need your help alot . thank you so much

Well... I did not re-read all the posts above, but to summarize someone suggested to look for gfortran and you verified it was available on your system. So, why to try the f77 command, when you already know you have a working fortran compiler called gfortran?!

Furhermore the f77 command is usually a symbolic link to an actual compiler, be it g77 or gfortran. You can create the link and let it point to the gfortran executable, that is as root do:

Code:

cd /usr/bin
ln -s /usr/bin/gfortran f77

then you can issue the f77 command but take in mind you're actually using gfortran.

Moreover, different flavors of fortran compilers (GNU fortran, G95, Intel Fortran, Portland Fortran) may have their own compiler options, but most of them are the same since they are part of a standard. So you can safely run the command

Code:

gfortran -C -o gme.e gme.f ft2d.f sub.f

without any problem. Hopefully!

hi and thanks for your help . actually i'm working on another pc so at first i typed " which gfortran " to be sure whether it has it or not. i'm not sure that i did the right thing but when i typed gfortran instead of f77 i didnt get f77 error and it was good cos i went one step forward . tnx for that .actually i did this :

khd@linux-4av4:~> which gfortran
/usr/bin/gfortran
khd@linux-4av4:~> cd /usr/bin
khd@linux-4av4:/usr/bin> ln -s /usr/bin/gfortran g77
ln: creating symbolic link `g77': Permission denied

khd@linux-4av4:/usr/local/GME> gfortran -C -o gme.e gme.f ft2d.f sub.f
/usr/lib/gcc/i586-suse-linux/4.3/../../../../i586-suse-linux/bin/ld: cannotopen output file gme.e: Permission denied
collect2: ld returned 1 exit status

i'm here waiting for your helps , thank u so much .
