Steps to update a basic installation of XL Fortran V10.1

You can use the xlf_install utility to update XL Fortran V10.1 when all the following conditions have been met:

  1. Issue the following command:
     # cd /home/root/update/xlf/mmmYYYY
    where mmmYYYY is the month and year of the PTF shipment date. (For example, jun2005 indicates a shipment date in June of 2005.)
  2. Issue the following command:
     # ./xlf_install -U 
  3. Complete the following steps from the xlf_install utility:
    1. Confirm that you want to proceed with uninstalling the outdated packages.
    2. Accept the licensing agreement and licensing information.
    3. Optional: Create symbolic links for the compiler invocations of XL Fortran V10.1 in the /usr/bin/ directory.
      Note:
      An alternative to this step is to add the path that contains the compiler invocations to the PATH environment variable. See Setting the PATH environment variable to include the path to the XL Fortran V10.1 invocations.
    When the update has been applied successfully, the xlf_install utility should generate the following message:
