Install GCC 4.9.2 on AIX as non -privilege user

[Liqin Wang]

Hi all, 

I need to install GCC 4.9.2 up on AIX 7.1 as non-privilege user, or in user space. There are set of RPM files that need to be installed there.
In order to do so, I need to build RPM database first. I have tried with:

Rpm --initdb  --dbpath /a/b

No error was shown. 
But when I run rpm  installation command, I got error of "packages.rpm" does not seem like a rpm file....


I need your helps to get this work done. 
The questions are:

1. Is it possible to install RPM based GCC on AIX in user space or non-privileged user?
2. Is there any instruction as how to do so?


Thanks a lot.

Tina
