install two different compiler version

UNIX AIX
1

Hi all.
I have a simple question.
There's a way to install under AIX system (5.3) two different compiler version, i.e. ibm xlf fortran 11 and 12?
Seems that smitty doesn't allows user to change the default installation path; it only allows you to save the replaced files of the superseded version.
I need two version of ibm compiler on the same environment.
Thanks in advance.

I can't speak to this exact problem, but I have a few comments that may start a discussion.

  1. If this were 6.1 you could install into WPARs

  2. If you virtualize you could have two LPARs that share resources (CPU/VIOS) and use a common NFS mount for source.

  3. The brute force way (when dealing with package based installs) is to install the package on a system, tar it up and then install elsewhere via the tar - this way the package install is "simultaneous" (as it is not done by the package manager) as opposed to an upgrade.
