Product Documentation
Abstract
This document contains a complete listing of releases, refreshes (also known as mod packs), and fix packs (also known as Updates) sorted by version for IBM XL C/C++ for Linux.
Content
Applications compiled with the XL C/C++ for Linux compiler require an equivalent or later VRMF version of the IBM XL C/C++ Runtime installed on the system to run. For systems that do not have the compiler installed, the standalone IBM XL C/C++ Runtime Package can be obtained from techdoc 7038813: Fix list for XL C/C++ Runtime for Linux .

Helpful Hints For Obtaining Technical Assistance:
Before you contact IBM Rational Compiler Support, gather the background information that you need to describe the problem. When you describe a problem to an IBM software support specialist, be as specific as possible and include all relevant background information so that the specialist can help you solve the problem efficiently. To save time, know the answers to these questions:
- Can the issue be reduced to a small test case?
- Review technote 1084174: Test Case Reduction Techniques for details.
- Can the test case be provided to IBM?
- Review technote 1260804: Test case preparation for IBM XL compilers support for details.
- What compiler version and fix pack level were you using when the problem occurred?
- This can be found by compiling with the -qversion=verbose compiler option.
- Do you have logs, traces, or messages that are related to the problem?
- Can you reproduce the problem? If so, what steps and compiler options do you use to reproduce it?
- Is there a workaround for the problem? If so, be prepared to describe the workaround.
If you have helpful information to diagnose or identify the problem on your system, you can provide this data by following the instructions to exchange information with IBM Technical Support .
