Installation Instructions
-------------------------

This file provides basic instructions for installing the patched file "libtl.so" into your existing Apache OpenOffice installation. You will need to do this replacement using a console (terminal) window and will likely need to use "root" (administrator) access to your system.


0.  Make sure OpenOffice is not being used.

1.  Open a console window and login as root with the following command:

    $ su -

2.  Locate where Apache OpenOffice is installed on your system:
    a) If you already know where Apache OpenOffice is located on your system, navigate
       to that directory. Example:

    $ cd /opt/openoffice4

    b) If you do not know this, you can use your package manager (e.g., RPM) to find
       this, or use the "locate" command. Examples:

    $ rpm -ql openoffice-core04-4.1.2-9782.x86_64 | grep libtl.so
    $ locate openoffice | grep program

    The commands show you the "program" sub-directory where Apache OpenOffice is
    installed.

    For illustration, let's assume "/opt/openoffice4" is the directory location of
    OpenOffice. Navigate to the "program" sub-directory:

3.  Navigate to the "program" sub-directory of your Apache OpenOffice installation:

    $ cd /opt/openoffice4/program

4.  List the files in the Apache OpenOffice program sub-directory:

    $ ls

    You should see a file listed as "libtl.so".

5.  Make a backup of the existing file by renaming it.
    You can leave this where it is if you like:

    $ mv libtl.so libtl.so.org

6.  Copy the new "libtl.so" provided by this hotfix to the "program" sub-directory.
    Use your download folder with the saved and extraced ZIP file to copy it to the
    "program" sub-directory. Use the following command to copy the file:

    $ cp -p /home/jane/Downloads/libtl.so .
    (the last dot "." is an abbreviation for the current directory)

7.  Verify that the "libtl.so" got placed in the "program" sub-directory.

    $ ls -al

    This will allow you to verify permission settings on the new file.

    Important:
    If it is NOT listed as "-r--r--r-- 1 root root", go to Step 8.

8.  Change file ownership and permissions.
    To correct the ownership and permission settings on the new "libtl.so", execute both
    commands still in the console window as root in the "program" sub-directory:

    $ chown root:root libtl.so
    $ chmod 444 libtl.so

9.  Now the patch work is done and you can exit the console window:

    $ exit

10. Start Apache OpenOffice as you normally would as a non-privileged user.
