Installing Scisoft 7.7 on Fedora Core 11
=======================================

There are three methods to install Scisoft 7.7; these are described
below in order of preference (best first), together with the pros
and cons of each method. 

Method #1 Installing from the online yum repository
---------------------------------------------------

Pros:

        *  your scisoft installation can automatically be kept
           aligned with the latest available bugfixes for this Scisoft
           release
        
        *  you can install all of Scisoft or only the parts you
           want

Cons:

        *  requires Fedora Core 11

Procedure:

        1) If you have a previous installation of Scisoft then back 
           it up and remove it using a method appropriate to it was
           installed (e.g. if you used 'yum' to install it now use
           'yum' to remove it).

        2) As root create /etc/yum.repos.d/scisoft.repo containing:

           [scisoft]
           name=Scisoft
           baseurl=ftp://ftp.eso.org/scisoft/scisoft7.7/linux/fedora11/yum-repo
           gpgcheck=0
           enabled=1

        3) As root run:

           yum clean all
           yum install scisoft-\*

           and when prompted, check the list of packages about to
           be installed looks sensible, and then allow yum to start
           installing the packages by pressing 'y'.

Method #2 Installing from RPMs 
------------------------------

Pros:

        *  you can install all of Scisoft or only the parts you
           want

Cons:

        *  requires Fedora Core 11, or that some dependencies are
           overridden using rpm's '--nodeps' option

Procedure:

        1) Download all RPMs at
           ftp://ftp.eso.org/scisoft/scisoft7.7/linux/fedora11/RPMs/,
           or copy them from the Scisoft DVD
           and save them to a directory, which we will call
           <scisoft-save-dir>.

        2) If you have a previous installation of Scisoft then back 
           it up and remove it using a method appropriate to it was
           installed (e.g. if you used 'yum' to install it now use
           'yum' to remove it).

        3) As root, run:

           rpm -ihv <scisoft-save-dir>/*.rpm

Method #3 Installing from tar.gz 
--------------------------------

Pros:

        *  May mean you can get Scisoft 7.7 running on unsupported
           versions of Linux (which is not supported).

Cons:

        *  you must install all of Scisoft and cannot install only
           the parts you want

        *  prerequisite libraries are not automatically checked at
           install-time
        
Procedure:

		1) Scisoft depends on several external packages which are
		   provided in the tarball. Some of the software will 
           work without these, but you will need to install them 
           if you want all of Scisoft to work. If you are using a 
           RPM compatible distribution you can try to download and
           install the following packages:
  			- SDL_image
			- SDL_ttf
  	        - compat-libf2c-34
		    - libgfortran
			- unixODBC 
           If you are using a non RPM based distribution you will 
           need to find the equivalent packages.

        2) Download the tar.gz file from
           ftp://ftp.eso.org/scisoft/scisoft7.7/linux/fedora11/tar/,
           or copy them from the Scisoft DVD
           and save it to a directory, which we will call
           <scisoft-save-dir>.

        3) If you have a previous installation of Scisoft then back 
           it up and remove it using a method appropriate to it was
           installed (e.g. if you used 'yum' to install it now use
           'yum' to remove it).

        4) As root, run:

           cd /
           tar xzf <scisoft-save-dir>/scisoft-*.tar.gz

Problems with SELinux and FC11
-----------------------------
Some software in Scisoft 7.7 such as inmidas conflict with SELinux 
which is installed by default on Fedora Core 11.
