The packages installed were...

-rw-r--r--    1 root     system       178381 Feb 15 2017  zlib-1.2.11-1.aix6.1.ppc.rpm

 

To uninstall these I use this:

 

rpm -e "libstdc++-8.1.0-2.ppc" gmp-6.1.2-1.ppc ncurses-6.1-2.ppc mpfr-3.1.2-3.ppc libmpc-1.0.3-1.ppc info-6.4-1.ppc
error: Failed dependencies:
        info is needed by (installed) AIX-rpm-7.2.3.15-1.ppc

 

I have no idea why "info" became a dependency of the already installed AIX-rpm-7.2.3.15-1.ppc package. I think it may have already been pre-installed so it just got upgraded with the dependency requirement?

 

If I try to leave the info package out of this, then i run into other dependency mess.

 

root@aix:rpm -e "libstdc++-8.1.0-2.ppc" gmp-6.1.2-1.ppc ncurses-6.1-2.ppc mpfr-3.1.2-3.ppc libmpc-1.0.3-1.ppc
error: Failed dependencies:
        libncurses.a(libncurses.so.6) is needed by (installed) info-6.4-1.ppc

 

Here is some other info..

 

root@aix: lslpp -l | grep "rpm"
  rpm.rte                   4.13.0.3  COMMITTED  RPM Package Manager
  rpm.rte                   4.13.0.3  COMMITTED  RPM Package Manager

Here are all the packages that are installed, the ones in bold are not needed.

root@aix: rpm -qa

expect-5.42.1-3.ppc
sudo-1.8.27-1.ppc

zlib-1.2.11-1.ppc
mpfr-3.1.2-3.ppc

root@aix: rpm --version
RPM version 4.13.0.1

How can I remove the recently installed GCC packages without breaking dependency for RPM as I do want that to remain on the system.

If I try to uninstall a single rpm package, i again end up at AIX-rpm being a dependency.

Commands like info, install-info are needed by rpm . So these are provided by the rpm.rte fileset itself. 

They are also coming from info rpm and going to the same location. If someone removes the rpm, the files will be gone.

So to avoid that, AIX-rpm has dependency on info rpm. From rpm.rte 4.13.0.4 onwards, the dependencies are removed as the files are going to a separate path "/usr/opt/rpm" .

You can install the rpm.rte fileset and downgrade the info rpm to (info-4.6) to come out of the situation.

Don't remove the info rpm as it is needed by other rpm package scripts.

I found ftp://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/INSTALLP/ppc/rpm.rte.4.13.0.6 and installed this using SMITTY installp.

 

If I check the RPM package installed, we can see..

However when I check the RPM version reported via --version I still get 4.13.0.1?

What is the issue here?

By the way I was able to get out of the dependency mess by upgrading the RPM package, had to rpm -e multiple packages together. Back to a clean "rpm -qa" list without all of the gcc dependencies. So your suggestion worked, I guess --version may not be updated?

Okay, it's a doubt that comes to everybody. 

There is a difference between the rpm.rte fileset version and the real rpm version.

The real rpm version ( rpm source code from community) shipped is still 4.13.0.1.

As a rte fileset for AIX, the version field is increased to "4.13.0.6" .

I don't think AIX has five field versioning system that formed the reason behind this confusion.
