* can I easily install GCC 7.2 & 8.1 at the same time?

* I know this is a classic problem. Just do not work with RPMs enough to know the answer.

* Removing libgcc-7.2.0-1.ppc and will need to remove at least the following;

# rpm -e libgcc-7.2.0-1.ppc

Hi !

Right now multiple version installation support is not available for any package in AIX toolbox. So, you can't install GCC 7.2 & 8.1 at the same time.

For your second query, you really don't need to remove rpm (rpm -e) and install newer version freshly.

You can update the package using yum (if yum is configured in your system).

Another way is to download all the required rpm in a directory and run the command: rpm -Uvh *

Thanks,

Morning Nitish,

Thank you.

• I know all that which you speak of.

• How can I install Spectrum Control using the newest libraries without breaking all the other packages, such as ssh & bash, & . . .

Hi,

1. GCC-7.2.0 and GCC-8.1.0 libraries are compatible. GCC-8.1 supports all the APIs which 7.2 provides. Any package which is built with GCC-7.2.0 should work with GCC-8.1, So, there should not be any question of incompatibility.

2. From where are you getting spectrum control, what is the source for it ? Is there any requirement of GCC-8.1 for this spectrum control ?

3. Updating GCC should NOT break any other packages.

Thanks and Regards,

Nitish
