No. You do not need to remove any previous version of Absoft Pro Fortran to install a later version.

Use the following instructions to install the product.

This document describes the steps required to correctly install Absoft Fortran 95 for Linux systems:

1. Installation.
2. Setting environment variables.
3. Optional packages.
4. Source code availability

STEP 1: To install Absoft Fortran 95, please run the installation script as root, alternatively you can install as a normal user however this configuration is not recommended. The installation script is located in the root directory on the CD-ROM, to run simply type:

./install

NOTE: If you are installing this product from a CD-ROM and the install script fails to run, it is likely that your system has mounted the CD-ROM without execute permission. Execute permission can be added to an already mounted CD-ROM using the mount command. An example:

mount -o remount,exec (mount_point or device)

where (mount_point or device name) is replaced by the actual mount point or device name for your system. See the manual page for mount for further information.

Your Absoft Pro Fortran serial number can be found on the inside front cover of the CD case or in your delivery email.

STEP 2: Before using this package, you need to create the ABSOFT environment variable and add the directory containing the Fortran 95 tools to your PATH environment variable. You should also add the appropriate set of commands to your startup script to avoid having to do this step each time you want to use the compilers.

If you are using bash, ksh, or sh, enter

ABSOFT=/opt/absoft11.0
PATH=$ABSOFT/bin:$PATH
export ABSOFT PATH

and add these commands to .bash_profile or .bashrc file in your home directory.

If using csh or tcsh, enter

setenv ABSOFT /opt/absoft11.0
set path = ( $path $ABSOFT/bin )

and add these commands to .tcshrc or .cshrc file in your home directory.

STEP 3: If you would like to use the -fast_math option (AMD only!) you will need to install an additional package.

libf2c:

f2c is a library that is necessary for linking to the AMD ACML libraries. Most major linux distributions come with this library, however it is generally not installed by default. Please install this package with the package manager provided with your distribution of Linux. Note: a few Linux distributions have renamed libf2c to libg2c. If you are using one of these distributions, you will need to specify the -use_g2c optin when using the -fast_math option.

STEP 4: If you are interested in obtaining the source code for the open source components listed in licenses/Copyrights_and_Licenses.pdf please follow the appropriate step below:

1. If you received a physical distribution of this product the source code is in the source directory on the CD

2. If you received a electronic delivery of this product please email sales@absoft.com to request the source code for the open source components included with this product.
