AUTO 07 Fortran Compiler Installation

[nabeels]

Hello everybody
I'm currently working on installing AUTO 07 software which is based on continuation method and can be use as a tool to analyze dynamic system in many scientific fields. This version requires installation of Fortran 95 compiler for the ubuntu Linux environment. Can I know how and from where I can install the compiler of Fortran 95?
Do I have to search for it in the interent or it is available ubuntu website?
Below is the result for running the command ./configure

Thank in advance for the help

If you search for "fortran" in Synaptic, you will see the package gfortran with the description "The GNU Fortran 95 compiler". Install it and you should be good to go.

I found it and it status is "installed". I'm not sure why it can't seen by the software?!!!
Any idea?
Thanks for the help

What version of Ubuntu and gfortran do you have? I have downloaded and compiled just fine Auto 07. I am using Ubuntu 9.10 with gfortran 4.4.1. I installed other libraries as well (motiff, and others described in the documentation) and it worked.

Thank you very much for the kind contribution
I'm using the same version as urs, i.e. 9.10 BUT not sure how to get the version of gfortran:confused:. This is the link I used to install Ubuntu 9.10: http://www.ubuntu.com/getubuntu/download-wubi
How did you install the other library? (motiff, and others described in the documentation)
Aren't they installed automatically when you install Ubuntu 9.10?

I used Ubuntu since 6.04 and I only did ugrades on my computer. But it should not matter how you installed Ubuntu. I use Synaptic package manager (from the System menu) to install new software. It is more powerful than "Software Center". You just search for the library/program they suggest to install, mark it for installation and apply. You want to install the development packages as well (for example libmotif-dev) in order to compile the program (most of them have -dev attached to the name). Did you install the "build-essential" package? What version of gfortran do you have installed?

Sorry for the silly questions, BUT how to install a new software from the Synaptic package.?
How can I know if the Fortran compiler is installed or not?:(
Are the development packages available in the Synaptic packages?
Thank you

A good place to start is the Ubuntu help. You can find it also on the internet:
https://help.ubuntu.com/9.10/add-applications/C/installing.html
As I said, I use Synaptic which gives more flexibility. The installed packages are marked with green in Synaptic.

Hi mionescu,

(not 100% sure if my post fits the thread but here it goes)
I'm installing auto-07p (Ubuntu 10.04) and it seems that I didn't set my environment variables correctly, since when I type "auto" I get the "no command 'auto' found" message. Here is a copy of my .profile, could you give a look?

# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.

# the default umask is set in /etc/profile
#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
# include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi

# 1st line introduced by ME: set environment variables to run AUTO
$HOME/auto/07p/cmds/auto.env.sh

Thanks,

[mionescu]

It seems fine to me. Try to add that line into .bash_profile as well.

Thanks for your reply.

I didn't find the file you mentioned still I figured out one solution (I post it for future occasions).

My home directory didn't have a bin subdirectory (I don't know if it's the Lucid's default structure, but it happened on both my laptop and my work desktop - both upgraded from 9.10). Because of that, and since the PATH definition was inside an If statement, it wasn't really defined. One possible solution (don't know if the best) is just to erase the if statement:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
fi

and define the path as follows:
PATH="$HOME/auto/07p/bin/:$PATH"

Probably one better solution would be to create a bin subdirectory in the home directory and add an additional line in the PATH's definition to include auto's binary (but still I have no experience on this stuff so...)
