CentOS - Aug 2010 - Downgrade libgcc & gcc packages (is there a clean way)

Hello all,

I have been tasked with "fixing" one of our CentOS boxes by somehow
downgrading the libgcc and gcc packages to a specific version (Required by the
Oracle Grid Control client). Normally I'd just remove and reinstall the
packages however removing libgcc is no fun as I found out the hard way it breaks
pretty much every package including rpm & yum. Is there an elegant way to
downgrade the currently installed libgcc & gcc packages?

Thanks,

Dan

Which specific version? Can't you You get away with the compat
packages? The rest should be compatible.

You could build your own gcc and libgcc from source of the right vintage,
putting them where they won't interfere with the CentOS versions. It takes
awhile, but gcc is quite capable of bootstrapping itself. 

How to get Oracle Grid Control working with that might remain a problem. Are
the libgcc libraries it wants to see in a separate namespace from the
current CentOS ones? If so you could just install them alongside and be
happy. If not, you might need to do something like set up a chroot for Grid
Control, with its preferred libraries there.
