On our develpoment system I've noticed a strange setup : we have the XL compiler 7 installed and runtime of 10. Is it a problem ?

I would recommend to upgrade the compiler to the 10 version. Is there any problem to be expected if we upgrade to version 10 ? Does anybody have any experience in such upgrade ?
Thanks for your help

Re: Should runtime version match compiler version ?2010-01-15T19:22:10ZThis is the accepted answer. This is the accepted answer.The C++ runtime is fully backward compatible with older versions of the C++ compiler. This is necessary because the runtime is dynamically linked, so a single runtime must support applications compiled with different compiler versions that coexist on your system.
The AIX operating system includes a recent version of the C++ runtime, and that is likely how you got the version you have installed. You can always download the latest version of the XL C++ runtime free from ibm.com (click "Support downloads" at http://www-01.ibm.com/software/awdtools/xlcpp/aix/), or let it be upgraded as you install AIX maintenance levels.
Of course, we always recommend our customers to upgrade to the latest available compiler. A better reason for doing so in your situation is that XLC V7 has gone out of service, so IBM will stop providing fixes for that product (for details see here: http://www-111.ibm.com/software/support/lifecycle/PLCDetail.wss?synkey=O544334T11167U30-B543715M90646C74-O451547B55846E36). If you do decide to upgrade, please let us know of your experience with the upgrade process; we're always looking for feedback on our installation/upgrade processes.

Thanks for your reply. We will install the latest compiler as you suggested. I will keep you informed of our experience.
Besides, I tried since days to reply using my account to this post but it failed (I tried with different browsers on different hardware) . I cannot find any email support to report this login problem.
