Will we ever see full C++11 (or C++14, it is 2018 after all!) support in xlC++ for AIX?

I cannot imagine us shipping a production application (on AIX!!!) to customers using a beta compiler release.

When will xlc compiler for AIX support more of the C++11 standard? Can't use boost either. 

Hard to develop software with outdated compiler.

Hi John,

Better support for C++11 and C++14 is underway and available in the beta. I welcome you to join the XL C/C++ for AIX beta program to get access to that support. Please apply by emailing xl-beta-join@ca.ibm.com. Kindly leave your name, company (if any), and email address.

Thanks,

Nicole

If I compile code with the XL C/C++ for AIX V16.1 compiler, will it run at a customer's site? Is an associated run-time library needed? Do the customer need to have a particular run-time library installed?

Thanks,

I see that the IBM XL C/C++ Runtime for AIX 16.1 has a prerequisite of at least IBM AIX V7.1 TL4.

We have quite a few customers still on V6.

Is there any chance that the rtl will be made available for earlier releases?

Hi John,

If you wish for your clients to run an application developed using the IBM XL C/C++ for AIX, V16.1 compiler, but your clients do not have the corresponding version of compiler or runtime already installed, then they need to install the Runtime Environment package. The standalone XL C++ runtime package for 16.1.0.1 can be obtained from techdoc 7038948: Fix list for XL C/C++ Runtime for AIX. 

You're correct that IBM XL C/C++ Runtime for AIX 16.1 has a prerequisite of at least IBM AIX V7.1 TL4. Our newer compilers do not support AIX 6.1 as this version of the OS has reached its end of service date in 2017.

Downward compatibility to AIX versions lower than the system that the application was built on is not supported. An application built on an AIX 7.1 system with xlC.rte VRMF 16.1.0.1 is supported on an AIX 7.1 system with the xlC.rte VRMF 16.1.0.1 (or later) runtime environment installed, but is not supported on an AIX 6.1 system, and is also not supported on any AIX version if the xlC.rte VRMF is lower than 16.1.0.1. Applications built on an AIX version might run on a lower AIX version; however, note that IBM does not warrant or support applications built on an AIX version that are run on a lower AIX version. See more details on Knowledge Center.

I know this is not the answer you wanted to hear. Please encourage your clients to move up to AIX 7.1. Also, libc++ is not deployed with the OS at this time.  If you are compiling with the xlclang++ invocation, please plan on providing libc++ in your packaging too.

Regards,

Nicole

Please note that the dependency on libc++ is only if your C++ application is compiled with xlclang.  You should be able to deploy C++ applications built with xlC without having to ship a separate runtime.  We're working to simplify your C++ deployments, this is definitely on our radar.  However, we don't have a timeline just yet.
