Troubleshooting
Problem
A compiler warning message is emitted during compilation after migration to AIX 7.1: 1501-285 (W) The current configuration file /etc/vac.cfg.71 was not customized. A configuration file for a lower OS level called /etc/vac.cfg.61 has been modified and may contain user customizations that you want to keep. If you want to use your previous modifications, copy them into the current configuration file.
Symptom
Starting with September 2010 PTF for XL C for AIX, V11.1 and XL C/C++ for AIX, V11.1 (11.1.0.3), AIX 7.1 is supported.
Regardless of whether or not you updated your compiler configuration files, you will see the following warning message after installing the 11.1.0.3 compiler PTFs and completing operating system migration to AIX 7.1. The compilation proceeds as expected.
1501-285 (W) The current configuration file /etc/vac.cfg.71 was not customized. A configuration file for a lower OS level called /etc/vac.cfg.61 has been modified and may contain user customizations that you want to keep. If you want to use your previous modifications, copy them into the current configuration file.
Resolving The Problem
There are two cases.
1. If you made modifications to your old configuration files (such as /etc/vac.cfg.53 or /etc/vac.cfg.61), follow the warning message to update /etc/vac.cfg.71 with these modifications. After the update, the warning message will disappear.
2. If you did not make modifications to your old configuration files (such as /etc/vac.cfg.53 or /etc/vac.cfg.61), you can dismiss the message. To dismiss the message, update the time stamp of file /etc/vac.cfg.71 using this command:
touch /etc/vac.cfg.71
