found in the online product documentation  
(https://www.ibm.com/docs/openxl-c-and-cpp-aix/17.1.0) or

2. Installation information
===========================

Operating system support
------------------------

Open XL C/C++ for AIX 17.1.0 is supported on the
following operating systems:

* IBM AIX 7.2 TL5 SP3

Uninstalling previous versions
------------------------------

Installing this version of the compiler does not remove or change 
previous versions of the compiler, only the C++ runtime library 
and the SMP runtime library are migrated to the new versions. 
This was achieved by differentiating the installation fileset names
from those of the previous versions, including the version, release
and modification level (V.R.M) in the name, and installing to new 
locations that include V.R.M in the installation paths.

Installation instructions
-------------------------

The installation path is:
/opt/IBM/openxlC/17.1.0/

To install the compiler, run the following command:
	
installp -aXYgd ./usr/sys/inst.images -e /tmp/install.log all
	
Language filesets for locales that you do not have on your machine 
will fail to install. If you require those languages, install the 
locale support from the OS installation media and reinstall the compiler.

To add the compiler invocations to your path, run the following 
command:

export PATH=/opt/IBM/openxlC/17.1.0/bin/:$PATH

See the "IBM Open XL C/C++ for AIX 17.1 Installation Guide" for
