*Some APARs may have been fixed first in another release of this product. In such cases, fixes have been ported to this release and APAR descriptions have been copied from the original APARs.

Prerequisites

IBM XL C/C++ for Linux, V12.1 compiler, at the base level (12.1.0.0) or higher.

See the "System Prerequisites" section in Chapter 1 of the Installation Guide for base level compiler prerequisite details.

Installation Instructions

RHEL 5, RHEL 6, SLES 10 and SLES 11
See Chapter 4 "Installing an update" in the Installation Guide (PDF).

RHEL 6

You might need this technote to help you with installing the compiler.

Note
: If the 32-bit libstdc++ package is not installed on a target RHEL6 system, running programs compiled with the XL C/C++ compiler may fail due to the missing shared library libstdc++.so.6. To resolve the issue, install the following 32-bit package from the RHEL6 distribution:

rpm -ivh libstdc++-4.4.4-13.el6.ppc.rpm

Download Package

Note: There is only one download package for both RHEL 5/RHEL 6 and SLES 10/SLES 11.
