IV. Installation Instructions
=============================

Complete the following steps to install the IBM XL C/C++ Enterprise Edition V7.0 
for AIX Run-Time Environment component:

1. Prior to installing the Run-Time Environment component, please note the current 
   C++ runtime level, so you can revert back to it if required.

2. Deinstall any XL C++ beta or evaluation run-time packages. 

3. Download the xlc.rte.70.aix.tar.Z archive.

4. Uncompress and untar the downloaded package into a new directory:

	a. To uncompress the file, use: uncompress xlc.rte.70.aix.tar.Z

	b. To untar the resulting file, use: tar -xvf xlc.rte.70.aix.tar 

5. Delete the .toc file in the download directory.  If no .toc file exists,
   proceed to step 6.

6. Use 'smit install_latest' to go to the appropriate installation screen in SMIT. 
   You must have root privileges.

7. Install the filesets:

	a. Specify the download directory location.

	b. Modify the installation options to suit your needs.

	c. The installation process writes a log to $HOME/smit.log.


V. Reverting to the previously installed C++ Runtime Level
==========================================================

To revert to the V6.0 C++ runtime level, use the following steps:

1. Download the base runtime and the fix level (if applicable) of
   the C++ runtime you recorded before installing the Run-Time Environment 
   component. The base runtime and fix levels can be found at:

        http://www.ibm.com/software/awdtools/vacpp/support/

   A compressed archive containing the base level C++ runtime libraries
   filesets can be obtained from:

   ftp://ftp.software.ibm.com/aix/products/ccpp/xlc.600.runtime.aix.tar.Z

2. Force install the base level of the C++ runtime with the
   -F option, using the following command.

   installp -aFXd <location> xlC.rte xlC.aix50.rte xlC.msg.LANG.rte

        where: <location> is the location of the install images

3. Apply the fix level (if required), using the following command:

   installp -aXd <location> <fileset_to_update>

        where: <location> is the location of the install images.
              <fileset> is the fileset to update.

   or commit the fix level, using:

   installp -acXd <location> <fileset>

        where: <location> is the location of the install images.
              <fileset> is the fileset to update.
